Question

I have a print-function:

myprintf("%d ..... other_things_to_print");  

• I call this myprintf() function from many different functions.

• Suppose function func() calls myprintf() but it has nothing to pass for the “%d” (shown as bold in the myprintf() above).

• I don’t wanna print zero in place of this “%d”

How can I avoid printing anything in place of “%d” here?

I have tried: ‘\b’, ‘ ‘ — but myprintf() is printing the equivalent integer values for these chars.

Please provide me some hint on this issue.

Thanks.

Best Regards,

If you don’t want to print the %d when no argument was supplied for it, then use an if()-else structure inside your myprintf() function to not output that position. Here is an example:

if( d_variable ) {
    printf("%d ..... other_things_to_print");
} else {
    printf("..... other_things_to_print");
}

This is what if-else is meant to allow you to do.
