Thread: Printing Current TIME

Hi ,

Its a code in module of my program, where I need to print current time (HH:MM:SS) at regular intervals. I excluded other code for understanding.

Code:

#include<time.h>
#include<stdio.h>
//#include<windows.h>

void delay(unsigned int t){        // loop for some delay.
    int k;
    while(t--)
        for(k=0;k<1275;k++);
}

void main(){

    printf("Time: %s",__TIME__);
    delay(10000);  // Sleep(10000);
    printf("\nTime: %s",__TIME__);

}

But when I am running this code I expect this to print difference in time due to delay.




But it doesn't enter the delay loop, why ?


Regards,
Raady.

__TIME__ is the time that the preprocessor is run (i.e. the time that that bit of code was compiled).

Also, don't use void main(void)... it's not standard C.

The loop

Code:

    while(t--)
        for(k=0;k<1275;k++);

is also likely to be optimised away by the compiler.

then how can I print time from system at regular intervals ?
