DATE:
REG:URK22cs3007
1) Write a C program to perform the sum of all elements stored in
an array.
AIM:
Find the sum of all stored array
ALGORITHM:
STEP 1: Start the program.
STEP 2: Initialize arr[]
STEP 3: Get the array from the user.
STEP 4: sum
STEP 5: Stop the program
PROGRAM:
#include <stdio.h>
void main()
{
int arr[]={1,2,3,4,5,6,};
int sum=0;
int length=sizeof(arr)/sizeof(arr[0]);
for(int i=0;i<length;i++)
{
sum=sum+arr[i];
}
printf("Sum of all elements of an array is : %d\n\n", sum);
}
OUTPUT:
RESULT:
The program is successfully executed.
2) Write a C program to get 10 numbers from the user and find the largest
and smallest number of the array along with the index value.
AIM:
Get number from user and find largest and smallest number.
ALGORITHM:
STEP 1: Start the program.
STEP 2: Initialization of array.
STEP 3: Get values from the user .
STEP 4: Stop the program.
PROGRAM:
#include<stdio.h>
int main()
{
int a[10], Size, i, Minimum, Min_Position, Maximum, Max_Position;
printf("\nPlease Enter the size of an array : ");
scanf("%d",&Size);
printf("\nPlease Enter %d elements of an array: \n", Size);
for(i=0; i<Size; i++)
{
scanf("%d",&a[i]);
}
Minimum = a[0];
Maximum = a[0];
for(i=1; i<Size; i++)
{
if(Minimum > a[i])
{
Minimum = a[i];
Min_Position = i;
}
if(Maximum < a[i])
{
Maximum=a[i];
Max_Position = i;
}
}
printf("\n Smallest element in an Array = %d", Minimum);
printf("\n Index position of the Smallest element = %d", Min_Position);
printf("\n Largest element in an Array = %d", Maximum);
printf("\n Index position of the Largest element = %d", Max_Position);
return 0;
}
OUTPUT:
RESULT:
The program is successfully executed and hence find the
largest and smallest number of an array
3) Write a C program to implement linear search.
AIM:
Write a C program to implement linear search.
ALGORITHM:
STEP 1: Start the program.
Step 2: Get the input value from user.
Step 3: Size and element of an array.
Step 4: Stop the program.
PROGRAM:
#include<stdio.h>
int main()
{
int a[20],i,x,n;
printf(“How many elements?”);
scanf(“%d”,&n);
printf(“Enter array element:\n”);
for(i=0;i<n;++i)
scanf(“%d”,&a[i]);
printf(“\nEnter element to search:”);
scanf(“%d”,&x);
for(i=0;i<n;++i)
if(a[i]==x)
break;
if(i<n)
printf(“Element found at index%d”,i);
else
printf(“Element not found”);
return 0;
}
OUTPUT:
RESULT:
The program is executed successfully and the size of array of the given
element is founded.
4. Write a program in C to read n number of values in an array
and display it in reverse order.
AIM:
Write a C program to read a n number of values in array and
display it in reverse order.
ALGORITHM:
STEP 1: Start the program.
STEP 2: write a program
STEP 3: get the n number of values from user
STEP 4: Stop the program
PROGRAM:
#include <stdio.h>
int main()
{
int arr[] = {1, 2, 3, 4, 5};
int length = sizeof(arr)/sizeof(arr[0]);
printf("Original array: \n");
for (int i = 0; i < length; i++) {
printf("%d ", arr[i]);
}
printf("\n");
printf("Array in reverse order: \n");
for (int i = length-1; i >= 0; i--) {
printf("%d ", arr[i]);
}
return 0;
}
OUTPUT:
RESULT:
The program is successfully executed and the values of arrays are arranged
in a reverse order.
