Std::cout Example
Example 1: std cout c++
#include <iostream> using std::cout; int main() { cout<<"Hello world"; return 0; }
Example 2: std::cout and cout
//c++ cout and std::cout both are same, but the only difference is that if we use cout, namespace std must be used in the program or if you are not using std namespace then you should use std::cout.
