Hello, C++

Read first Task 1

cout prints text and numbers. endl ends the line.

Definition and example

Hello, C++ is the focus of this lesson. cout prints text and numbers. endl ends the line. The task asks you to apply that idea in a small example: Which line prints text to the screen. Before you run the code, predict what should happen. Then Inspect the program output and the compiler message if it fails and compare it with your prediction. If the result differs, change one relevant line and run it again. Testing one change at a time makes the cause of a result easier to understand.

C++ 1 automatic check Section 1 · First programs

Code editor Ctrl + Enter runs

// TASK hello-c-01: Which line prints text to the screen?
// STEPS: Read the explanation. Change one relevant line at a time, then run the code and compare the result with the check on the right.
#include <iostream>
using namespace std;

int main() {
    cout << "TODO" << endl;
    return 0;
}
