They don't need to match (either in C or in C++). The function declarations
are more for verifying whether you are passing the "right type of
arguments". The compilers do not check the names. In fact, you can even
omit the variable names altogether in the function declarations. For
example, the following code is completely valid.
#include <iostream>
using std::cout; using std::cin;
using std::endl;
double sum(const double& , const double&);
int main() {
double a, b, c;
cout << "Enter two numbers" << endl;
cin >> a >> b;
c = sum(a, b);
cout << a << " + " << b << " = " << c << endl;
return 0;
}
double sum(const double& p, const double& q) {
return(p+q);
}
