C Program to Search a Given Number Using Linear Search

PROGRAM:

#include<stdio.h>

main()

{

   int nums[40];

   int key,i,n,location=0;

   clrscr();

   printf("Enter the size of an array:\n");

   scanf("%d",&n);

   printf("Enter the array element:\n");

   for(i=0;i<n;i++)

   scanf("%d",&nums[i]);

   printf("Enter the key element:");

   scanf("%d",&key);

   for(i=0;i<n;i++)

   if(nums[i]==key)

     {

        location=i+1;

        break;

     }

   if(location==0)

     {

        printf("The given key element doesn't exist and is not found");

     }

   else

   printf("The given key element %d exists and is found %d position",key,location);

   getch();

}
