C-Program For Linear Search

#include<stdio.h>

int main(){

    int a[20],i,n,s,var=0;

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

    scanf("%d",&n);

    printf("Enter the elements of the array: ");

    for(i=0;i<=n-1;i++){

         scanf("%d",&a[i]);

    }

    printf("Enter the Element to be searched: ");

    scanf("%d",&s);

    for(i=0;i<=n-1;i++){

         if(a[i]==s){

             var=1;

             break;

         }

    }

    if(var==0)

         printf("The number is not in the list");

    else

         printf("The element is found");

    return 0;

}

output:

Enter the size of an array: 6

Enter the elements of the array: 5 8 9 1 3 4

Enter the Element to be searched: 9

The Element is found
