C Programming: Convert a given integer to hours, minutes and seconds

C Code:

#include <stdio.h>
int main() {
	int sec, h, m, s;
	printf("Input seconds: ");
	scanf("%d", &sec);
	
	h = (sec/3600); 
	
	m = (sec -(3600*h))/60;
	
	s = (sec -(3600*h)-(m*60));
	
	printf("H:M:S - %d:%d:%d\n",h,m,s);
	
	return 0;
}

Sample Output:

Input seconds: 25300                                                   
H:M:S - 7:1:40

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().
