Below is a simple C program that searches for an element in an array and prints the index if the element is found or a message indicating that the element is not present .
Program :
#include <stdio.h>
#include <conio.h>
int main()
{
int i,n,key;
printf(“Enter size of the array : “);
scanf(“%d”, &n);
int arr[n];
printf(“Enter elements in array : “);
for(i=0; i<n; i++)
{
scanf(“%d”,&arr[i]);
}
printf(“Enter the key : “);
scanf(“%d”, &key);
for(i=0; i<n; i++)
{
if(arr[i]==key)
{
printf(“element found “);
return 0;
}
}
printf(“element not found”);
}
Output :
