C Input Output statement and Expressions: Exercise-6 with Solution

Write a program in C that takes minutes as input, and display the total number of hours and minutes.

Pictorial Presentation:

C Input Output: Calculate the total number of hours and  minutes

Sample Solution:

C Code:

#include <stdio.h>
int tot_mins;  /* given number of minutes */
int hrs;          /* number of hours (to be computed) */
int mins;        /* number of minutes (to be computed) */

const int MINaHOUR = 60;      /* number of minutes in an hour */

char line_text[50];      /* line of input from keyboard */

int main() {
	printf("Input minutes: ");
	fgets(line_text, sizeof(line_text), stdin);
	sscanf(line_text, "%d", &tot_mins);

	hrs = (tot_mins / MINaHOUR);
	mins = (tot_mins % MINaHOUR);

	printf("%d Hours, %d Minutes.\n", hrs, mins);


Sample Output:

Input minutes: 546                                                                                            
9 Hours, 6 Minutes.

C Programming: Tips of the Day

How to increment a pointer address and pointer's value?

First, the ++ operator takes precedence over the * operator, and the () operators take precedence over everything else.

Second, the ++number operator is the same as the number++ operator if you're not assigning them to anything. The difference is number++ returns number and then increments number, and ++number increments first and then returns it.

Third, by increasing the value of a pointer, you're incrementing it by the sizeof its contents, that is you're incrementing it as if you were iterating in an array.
