sub routines and clearing the screen

How do I make sub routines, and how do i clear the screen? thanks

state your compiler for clearing screen...sub routines are simple...

first off: they're not suroutines, they're functions. they're really simple to do:

Code:

#include <stdio.h>
void /*no return value*/ myfunc(void/*no input*/)
{
    printf("Tada!\n");
}

int main(void)
{
    myfunc();
    return 0;
}

that code calls the function myfunc() to display "Tada!" on the screen.

passing a value to a function is simple, too:

Code:

#include <stdio.h>
void myfunc(int numtimes)
{
    int x;
    for(x=0;x<numtimes;x++)
        printf("Tada!\n");
}

int main(void)
{
    myfunc(5);
    return 0;
}

and that should display Tada! 5 times.where I wrote int numtimes in the function declaration, it tells the compiler that it needs to be passed an integer value to wrok properly.

Oh yeah, I'm in th C++ board...just change all the printf's to cout's
