bookBreak/Continue Statements

You are already familiar with the break statement. We used it to go out of the switch statement. You can use the break to go out of the loop (break it). The following code goes out of the loop when x is equal to 3:


              
123456

            
for (int x = 1; x < 5; x++) {
    cout << x << endl;
    if (x == 3) {
        break;
    }
}
copy

The program stopped the execution of the code block in the loop, since we add the break statement with the condition of the stop.

There is another way to skip some code. The statement continue breaks one iteration in the loop, if there is a special condition, and continues with the next iteration. For example:


              
123456

            
for (int x = 1; x < 5; x++) {
    if (x == 3) {
        continue;
    }
    cout << x << endl;
}
copy

We skip here the iteration when x is equal to 3.

Be careful with Break/Continue statements since they can skip the important part of code ruining your program.

The vending machine that dispensed drinks ran out of cola, which was number 7 on a list of 10 drinks. The code prints the list of drinks’ numbers in descending order, skipping cola. Fill gaps.

#include
using namespace std;

int main() {
    for (int x = ; x > 0; ) {
        if (x == 7) {
            ;
        }
        cout << x << endl;
    }
    return 0;
}
