BINARY SEARCH USING C PROGRAM

---

---

1. Write a simple code for binary search in c programming language

2. Wap a c program to search an element in an array using binary search

#include<stdio.h>

int main(){

    int a[10],i,n,m,c=0,l,u,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 number to be search: ");

    scanf("%d",&m);

    l=0,u=n-1;

    while(l<=u){

         mid=(l+u)/2;

         if(m==a[mid]){

             c=1;

             break;

         }

         else if(m<a[mid]){

             u=mid-1;

         }

         else

             l=mid+1;

    }

    if(c==0)

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

    else

         printf("The number is found.");

    return 0;

}

Sample output:

Enter the size of an array: 5

Enter the elements in ascending order: 4 7 8 11 21

Enter the number to be search: 11

The number is found.
