clang does not recognize std::cout
Step 1: Ensure you have included the necessary header file for input and output operations.
#include <iostream>
Step 2: Use the standard namespace to access the cout object without the 'std::' prefix.
using namespace std;
Step 3: Write your C++ code using the 'cout' object.
int main() {
cout << "Hello, World!" << endl;
return 0;
}
