[c-prog] Is this a good practise to call fuction ???

[shamir shakir]

Hi
Today I found a new (or probably) bad thing. I use to call fuction for
anything I need. But It takes valuable time taking value and returning
something.
 :(

// This code describe how bad , calling fuction is...

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

unsigned long int fuction(long long i)
{
    // Do something ...

    return i ;
}

int main()
{
    unsigned long long i;
    time_t end, start;


    start  = clock() ;
        for(int i=0; i<1000; i++)
            for(int j=0; j<1000; j++)
                for(int k=0; k<1000; k++) ;
    end = clock() ;

    printf("IN MAIN FUNCTION  ... \n ") ;
    printf("\t Total clock : %u \n", end-start) ;


    start = clock() ;
        for(int i=0; i<1000; i++)
            for(int j=0; j<1000; j++)
                for(int k=0; k<1000; k++)
                    fuction(i) ;
    end = clock() ;

    printf("IN SUB FUNCTION .... \n") ;
    printf("\t Total clock : %u \n ", end-start ) ;
    printf("\nFunctions take a lot of time :( " ) ;

    return 0 ;
}


Now , I just want to know is this a good practice to work and utilize
function calling? Or I'm just gonna work with main?
