WEEK-1
i).Program to Print a Message:
#include <stdio.h>
int main()
{
printf("Hello, World!");
return 0;
}
Output:
Hello, World!
ii).Read and Print an Integer
#include <stdio.h>
int main()
{
int num;
printf("Enter an integer: ");
scanf("%d", &num);
printf("You entered: %d\n", num);
return 0;
}
Output:
Enter an integer: 5
You entered: 5
iii).Read Two Integers and Add Them
#include <stdio.h>
int main()
{
int a, b, sum;
printf("Enter two numbers: ");
scanf("%d %d", &a, &b);
sum = a + b;
printf("Sum = %d\n", sum);
return 0;
}
Output:
Enter two numbers: 4 5
Sum = 9
iv).Read and Print a Float
#include <stdio.h>
int main()
{
float a;
printf("Enter a float value: ");
scanf("%f", &a);
printf("You entered: %.2f\n", a);
return 0;
}
Output:
Enter a float value: 4.5
You entered: 4.50
v).Read and Print a Character
#include <stdio.h>
int main()
{
char ch;
printf("Enter a character: ");
scanf("%c", &ch);
printf("You entered: %c\n", ch);
return 0;
}
Output:
Enter a character: s
You entered: s
WEEK-2
i). Sum and average of 3 numbers:
#include <stdio.h>
int main()
float num1, num2, num3, sum, average;
// Input three numbers
printf("Enter three numbers: ");
scanf("%f %f %f", &num1, &num2, &num3);
// Calculate sum and average
sum = num1 + num2 + num3;
average = sum / 3;
// Output results
printf("Sum = %.2f\n", sum);
printf("Average = %.2f\n", average);
return 0;
Output:
Enter three numbers: 3 5 6
Sum = 14.00
Average = 4.67
ii).Conversion of Fahrenheit to Celsius and vice versa
----------Conversion of Fahrenheit to Celsius-------
#include <stdio.h>
int main() {
float fahrenheit, celsius;
printf("Enter temperature in Fahrenheit: ");
scanf("%f", &fahrenheit);
// Conversion formula
celsius = (fahrenheit - 32) * 5.0 / 9.0;
// Output result
printf("Temperature in Celsius: %.2f\n", celsius);
return 0;
}
Output:
Enter temperature in Fahrenheit: 35
Temperature in Celsius: 1.67
-----------Conversion of Celsius to Fahrenheit-----------
#include <stdio.h>
int main() {
float celsius, fahrenheit;
printf("Enter temperature in Celsius: ");
scanf("%f", &celsius);
// Conversion formula
fahrenheit = (celsius * 9.0 / 5.0) + 32;
printf("Temperature in Fahrenheit: %.2f\n", fahrenheit);
return 0;
}
Output:
Enter temperature in Celsius: 3
Temperature in Fahrenheit: 37.40
iii).Simple interest calculation
#include <stdio.h>
int main()
float principal, rate, time, interest;
printf("Enter Principal amount (P): ");
scanf("%f", &principal);
printf("Enter Rate of interest (R): ");
scanf("%f", &rate);
printf("Enter Time (T in years): ");
scanf("%f", &time);
// Calculate Simple Interest
interest = (principal * rate * time) / 100;
printf("Simple Interest = %.2f\n", interest);
return 0;
Output:
Enter Principal amount (P): 10000
Enter Rate of interest (R): 5
Enter Time (T in years): 2
Simple Interest = 1000.00
