The terms "parameter" and "argument" are very often used interchangeably, but they actually mean different things.

Parameters appear on a function signature when you are defining a function. Example:

int add(int a, int b) {
return a + b;
}
// parameters are: a, b

Arguments are objects you pass to functions during function call. Example:

int main() {
add(3, 5);
}
// arguments are: 3, 5
