Ex.No : Conditional Statements
Date :
Aim :
To Write a program to execute some specific statements based on the test condition
Program :
def main():
# Test condition
x = 10
# Execute specific statements based on the test condition
if x > 5:
# Statements to execute if condition is true
print("x is greater than 5")
print("Executing specific statements...")
else:
# Statements to execute if condition is false
print("x is not greater than 5")
print("Executing alternative specific statements...")
if __name__ == "__main__":
main ()
Output:
The variable x is assigned the value 10.
The if statement checks if x is greater than 5.
If the condition is true, it executes specific statements inside the if block.
If the condition is false, it executes specific statements inside the else block.
Result :
Thus the Conditional Statements are executed and verified successfully.

Ex.No : Nested loop
Date :
Aim :
To Write programs to implement nested loop
Program :
def multiplication_table(n):
# Nested loop to generate multiplication table
for i in range(1, n+1):
for j in range(1, 11):
print(i, "*", j, "=", i*j)
print() # Print an empty line after each row
# Call the function to print multiplication table up to 5
multiplication_table(5)
Output:
This program prints the multiplication table up to a specified number n. It uses a nested loop
with one loop iterating over the numbers from 1 to n (the outer loop), and another loop
iterating over the numbers from 1 to 10 (the inner loop) to generate the multiplication table
for each number.
Result :
Thus the Nested loop are executed and verified successfully.

Ex.No : Array
Date :
Aim :
To Write a program in C to get the largest element of an array using the function
Program :
#include <stdio.h>
// Function to find the largest element in an array
int findLargest(int arr[], int size) {
int max = arr[0]; // Assume the first element as the maximum
// Iterate through the array to find the maximum element
for (int i = 1; i < size; i++) {
if (arr[i] > max) {
max = arr[i];
}
}
return max;
}
int main() {
int arr[] = {5, 10, 3, 8, 15};
int size = sizeof(arr) / sizeof(arr[0]);
// Call the function to find the largest element
int largest = findLargest(arr, size);
// Print the result
printf("The largest element in the array is: %d\n", largest);
return 0;
}
Downloaded by Judith Petrizia (petri.success@gmail.com)
lOMoARcPSD|46270988
Output:
The findLargest function takes an array arr and its size as parameters and returns the largest
element in the array.
Initially, it assumes the first element of the array as the maximum.
Then, it iterates through the array starting from the second element and updates the maximum
if it finds a larger element.
In the main function, an array arr is defined with some elements, and its size is calculated.
The findLargest function is called with the array and its size as arguments, and the result is
printed.
Result :
Thus the Array Function are executed and verified successfully.

Ex.No : Prime Number
Date :
Aim :
To Display all prime numbers between two intervals using functions.
Program :
#include <stdio.h>
#include <stdbool.h>
// Function to check if a number is prime
bool isPrime(int num) {
if (num <= 1) {
return false;
}
for (int i = 2; i * i <= num; i++) {
if (num % i == 0) {
return false;
}
}
return true;
}
// Function to display prime numbers between two intervals
void displayPrimeNumbers(int start, int end) {
printf("Prime numbers between %d and %d are:\n", start, end);
for (int i = start; i <= end; i++) {
if (isPrime(i)) {
printf("%d ", i);
}
}
printf("\n");
}
Downloaded by Judith Petrizia (petri.success@gmail.com)
lOMoARcPSD|46270988
int main() {
int start, end;
// Input two intervals
printf("Enter the start and end of the interval: ");
scanf("%d %d", &start, &end);
// Call the function to display prime numbers between the intervals
displayPrimeNumbers(start, end);
return 0;
}
Explanation:
The isPrime function checks if a number is prime. It returns true if the number is prime, and
false otherwise.
The displayPrimeNumbers function takes two integers start and end as input and prints all
prime numbers between these two intervals.
In the main function, it prompts the user to input the start and end of the interval.
Then, it calls the displayPrimeNumbers function with the provided intervals as arguments.
Inside the displayPrimeNumbers function, it iterates through the numbers from start to end
and checks if each number is prime using the isPrime function. If a number is prime, it prints it.
Result :
Thus the Prime Number programs are executed and verified successfully.

Ex.No : Recursion
Date :
Aim :
To Reverse a sentence using recursion
Program :
#include <stdio.h>
#include <string.h>
// Function to reverse a sentence using recursion
void reverseSentence(char sentence[]) {
// Base case: if the string is empty or contains only one word
if (strlen(sentence) == 0 || strchr(sentence, ' ') == NULL) {
printf("%s ", sentence);
return;
}
// Find the first occurrence of space
char *firstSpace = strchr(sentence, ' ');
if (firstSpace == NULL) { // If there's no space, it's the last word
printf("%s", sentence);
return;
}
// Recursively call reverseSentence with the substring after the space
reverseSentence(firstSpace + 1);
// Replace the space with '\0' to print the word
*firstSpace = '\0';
printf("%s ", sentence);
}
int main() {
Downloaded by Judith Petrizia (petri.success@gmail.com)
lOMoARcPSD|46270988
char sentence[100];
// Input the sentence
printf("Enter a sentence: ");
fgets(sentence, sizeof(sentence), stdin);
// Call the function to reverse the sentence
printf("Reversed sentence: ");
reverseSentence(sentence);
return 0;
}
Explanation:
The reverseSentence function takes a character array sentence as input and reverses
the sentence using recursion.
The base case checks if the string is empty or contains only one word (i.e., no space). If
so, it prints the word and returns.
Otherwise, it finds the first occurrence of a space using strchr function.
It then recursively calls reverseSentence with the substring after the space.
After the recursion, it replaces the space with '\0' to print the word and prints the word.
In the main function, it inputs the sentence using fgets and calls reverseSentence to
reverse the sentence.
Result :
Thus the Reverse a Sentence programs are executed and verified successfully.

Ex.No : Concatenate Two Strings
Date :
Aim :
To Write a C program to concatenate two strings
Program :
#include <stdio.h>
#include <string.h>
int main() {
char str1[100], str2[100];
// Input the first string
printf("Enter the first string: ");
scanf("%s", str1);
// Input the second string
printf("Enter the second string: ");
scanf("%s", str2);
// Concatenate the two strings
strcat(str1, str2);
// Print the concatenated string
printf("Concatenated string: %s\n", str1);
return 0;
}
Downloaded by Judith Petrizia (petri.success@gmail.com)
lOMoARcPSD|46270988
Explanation:
This program first defines two character arrays str1 and str2, each with a size of 100
characters.
It then prompts the user to input two strings, one by one, using scanf.
After that, it uses the strcat function from the <string.h> library to concatenate str2 to the end
of str1.
Finally, it prints the concatenated string str1.
Result :
Thus the Concatenation of Two String programs are executed and verified successfully.

#include <stdio.h>
// Define a structure for storing student information
struct Student {
char name[50];
int age;
float marks;
};
int main() {
// Declare a variable of type struct Student
struct Student student;
// Input student information
printf("Enter student name: ");
scanf("%s", student.name);
printf("Enter student age: ");
scanf("%d", &student.age);
printf("Enter student marks: ");
scanf("%f", &student.marks);
// Display student information
printf("\nStudent Information\n");
printf("Name: %s\n", student.name);
printf("Age: %d\n", student.age);
printf("Marks: %.2f\n", student.marks);

lOMoARcPSD|46270988
return 0;
}
Explanation:
This program defines a structure Student with three members: name, age, and marks. It
then declares a variable student of type struct Student to store the information of one student.
The program prompts the user to input the student's name, age, and marks. After
inputting the information, it displays the student's information on the console.
Result :
Thus the above programs are executed and verified successfully.

Explanation:
This program reads student data from a file named student_data.txt.
It assumes that each line of the file contains the student's name followed by the marks
obtained in three subjects.
It calculates the total marks obtained by each student and stores them in a structure array
students.
After reading all the data, it prints the total marks obtained by each student.
It then determines the topper of the class by finding the student with the highest total
marks and prints their name.
Result :
Thus the above programs are executed and verified successfully.
