Below C program will search given number in an array and will display the location of the number being searched if it is present.

 

#include <stdio.h>

int main()

{

   int arr[250], search, n, i;

   printf("Please enter how many elements should be available in an array\n");

   scanf("%d",&n);

 

   printf("\nPlease enter %d numbers or integers one by one", n);

 

   for (i = 0; i < n; i++)

      scanf("%d", &arr[i]);

 

   printf("\nPlease enter the number you want to search");

   scanf("%d", &search);

 

   for (i = 0; i < n; i++)

   {

      if (arr[i] == search)  

      {

         printf("\n%d is present at location %d\n", search, i+1);

         break;

      }

   }

   if (i == n)

      printf("%d is not available in the array.\n", search);

   return 0;

}

 

Output:

Please enter how many elements should be available in an array

3

Please enter 3 numbers or integers

10

20

30

Please enter the number you want to search

20

20 is present at location 2
