Write a C program for binary search in sorted array.

Solution: #include <stdio.h> int main() {    int c, first, last, middle, n, search, array[100];    printf("Enter number of elements\n");    scanf("%d",&n);    printf("Enter %d integers\n", n);    for (c = 0; c < n; c++)    {       scanf("%d",&array[c]);    }    printf("Enter value to find\n");    scanf("%d", &search);    first = 0;    last = n - 1;    middle = (first+last)/2;    while (first <= last)    {       if (array[middle] < search)       { first = middle + 1;       }       else if (array[middle] == search)       { printf("%d found at location %d.\n", search, middle); break;       }       else last = middle - 1; //       printf("%d\n",middle);       middle = (first + last)/2;   //     printf("%d\n",middle);    }    if (first > last)       printf("Not found! %d is not present in the list.\n", search);
