This exercise is taken from Chapter 2 of the book,  "Beginning C", 5th edition . This is my solution to the problem. https://github.com/pereiradaniel/beginning_c/blob/master/ch2/exercises/2_1/exercise2_1.c // Exercise 2-1 // Write a program that prompts the user to enter a distance in inches and // then outputs that distance in yards, feet, and inches. // There are 12 inches in a foot and 3 feet in a yard. #include <stdio.h> int main(int argc, char* argv[]) { // Constants for conversion process: const int inches_per_foot = 12; const int feet_per_yard = 3; // Variables for user input and calculations: int input = 0, inches = 0, yards = 0, feet = 0; // Prompt user for input in inches: printf("Enter number of inches for conversion to yards, feet, inches: "); scanf(" %d", &input); inches = input; // Convert inches into yards, feet, inches: feet = inches / inches_per_foot; yards = feet /...
