strcpy problem
I have the following code, and am trying to copy an array of charactes from one variable to another:
"name" is declared somewhere else in the program, as char[15]..Code:char name[15]; int age; cout << "Name:"; cin.getline(n, 15); cout << "Age:"; cin >> a; age = a; strcpy(name, n);
The error i'm getting is that "strcpy" is an undeclared identifier.
Have you put #include <cstring> at the top of your program?
"Owners of dogs will have noticed that, if you provide them with food and water and shelter and affection, they will think you are god. Whereas owners of cats are compelled to realize that, if you provide them with food and water and shelter and affection, they draw the conclusion that they are gods."

Or just write one for fun.
Code:char * strcpy(char * target, char * source){ char * index = target; while(*source != 0) { *(index++) = *(source++); } *index = 0; return target; }
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
