C/C++ program to add N distances given in inch-feet system using Structures

// C program for the above approach

#include "stdio.h"

// Struct defined for the inch-feet system
struct InchFeet {

    // Variable to store the inch-feet
    int feet;

// set of Inch Feet distances

        // feet and inch
        feet_sum += arr[i].feet;

    }

    // If inch sum is greater than 11
    // convert it into feet
    // as 1 feet = 12 inch
