C Exercises: Calculate the total number of hours and minutes

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);

	return(0);
}

Sample Output:

Input minutes: 546                                                                                            
9 Hours, 6 Minutes.

C Programming: Tips of the Day

Static variable inside of a function in C

The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().

The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.

The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
