Part of the Fundamentals section of Coddy's C++ journey — lesson 46 of 74.

The continue statement stops the current iteration and continues to the next iteration. For example:

for (int i = 3; i < 9; i++) {
	if (i == 5) {
		continue;
	}
	std::cout << i << std::endl;
}

The loop will iterate through all of the numbers. When it reaches ⁣i=5 it will skip that iteration and continue to the next one. The output is:

Notice, number 5 is not in the output.

Challenge

Beginner

You are given a code that prints the numbers from 1 to 20 (including).

Your task is to add if and continue statements so that only the even numbers will be printed (2, 4, 6, ...).

Cheat sheet

The continue statement stops the current iteration and continues to the next iteration:

for (int i = 3; i < 9; i++) {
	if (i == 5) {
		continue;
	}
	std::cout << i << std::endl;
}

This will skip the iteration when i=5 and output:

Try it yourself

#include <iostream>

int main() {
    for (int i = 1; i <= 20; i++) {
        std::cout << i << std::endl;
    }
    return 0;
}
