Because apparently I don't have one. This code is from Teach Yourself C++ in 21 Days, listing 5.7, which is supposed to be written with the ASCII standard. I get the error message ISO C++ forbids declaration of ' from Dev C++ on line 25 (an opening brace for the function VolumeCube). The code is exactly as it appears in the book, save for "using namespace std". Thanks in advance.

Code:
#include <iostream>
using namespace std;

int VolumeCube(int length, int width = 25, int height = 1);

int main()
{
    int length = 100;
    int width = 50;
    int height = 2;
    int volume;
    
    volume = VolumeCube(length, width, height);
    cout << "First volume equals: " << volume << "\n";
    
    volume = VolumeCube(length, width);
    cout << "Second time volume equals: " << volume << "\n";
    
    volume = VolumeCube(length);
    cout << "Third time volume equals: " << volume << "\n";
    return 0;
}

VolumeCube(int length, int width, int height)
{
    return (length * width * height);
}
