C-Program For Binary Search

#include<stdio.h>

int main(){

    int a[10],i,n,e,var=0,low,high,mid;

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

    scanf("%d",&n);

    printf("Enter the elements in ascending order: ");

    for(i=0;i<n;i++){

         scanf("%d",&a[i]);

    }

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

    scanf("%d",&e);

    low=0,high=n-1;

    while(low<=high){

         mid=(low+high)/2;

         if(e==a[mid]){

             var=1;

             break;

         }

         else if(e<a[mid]){

             high=mid-1;

         }

         else

             low=mid+1;

    }

    if(var==0)

         printf("The Element is not found.");

    else

         printf("The Element is found.");

    return 0;

}

output:

Enter the size of an array: 6

Enter the elements in ascending order: 1 3 6 8 9 13

Enter the Element to be searched: 9

The Element is found.
