I am trying to compile the simple program below. But, it's not compiling & gives error:
error C2065: 'cout' : undeclared identifier
I want to ask you that why this program doesn't work though I've included iostream
header file in it?
#include <iostream>
void function(int) { cout << “function(int) called” << endl; }
void function(unsigned int) { cout << “function(unsigned int) called” << endl; }
int main()
{
function(-2);
function(4);
return 0;
}
Thanks in advance.
The cout stream is defined in the std namespace. So to name it you write:
std::cout
If you want to shorten this to cout then you can write
using namespace std;
or
using std::cout;
before writing cout.
Any good documentation source will tell you which namespace contains an object. For instance: http://en.cppreference.com/w/cpp/io/cout
You have to write std::cout
or add using std;
