1: The concept of argument parameter is clear

Note the difference between invocation, declaration, and definition.

The invocation of the past is an argument, and the declaration and definition are all parameters used.

Example:

Funcoperate (int a); This is a function declaration, and the parameters are all formal arguments;

int main ()

{

int b=0;

Fucopera (b); The main function calls the external function, and sends past arguments;

}

Funcopera (int a)//This is a function definition;

{

Alert ("a");

}
