Default arguments in C


Is it possible to provide default values to function arguments in C? For example:

void display(int a, int b = 10) {
    // do something
}
    
main() {
    display(1);
    display(1,2); // override default value
}

Visual Studio 2008, complains that there is a syntax error in void display(int a, int b = 10). If this is not legal in C, what is the alternative?


Solution

  • Default parameters is a C++ feature.

    C has no default parameters.
