C++: Break and Continue Statement

Break statement is used to stop the process or execution of code. It works as an exit statement. Continue statement is also known as the jump statement. It is used to skip a segment of code.

Examples of Break and Continue in C++

Syntax of Break Statement

break;

Syntax of Continue Statement

continue;

Implementation of Break Statement in C++

Problem 1: Breaking out of a loop

Write a program to to exit a while loop early when the user enters the letter ‘q’.

Run 
 
#include <iostream>
using namespace std;

int main() {
    char c;

    cout << "Enter a character ('q' to quit): ";
    cin >> c;

    while (c != 'q') {
        cout << "You entered: " << c << endl;
        cout << "Enter a character ('q' to quit): ";
        cin >> c;
    }

    cout << "Quitting program." << endl;

    return 0;
}

Output

Enter a character ('q' to quit): q
Quitting program.

Problem 2: Breaking out of a switch statement

Write a program to exit a switch statement early based on the value of a variable.

Run 
 
#include <iostream>
using namespace std;

int main() {
    int x;

    cout << "Enter a number: ";
    cin >> x;

    switch (x) {
        case 1:
            cout << "You entered 1." << endl;
            break;
        case 2:
            cout << "You entered 2." << endl;
            break;
        case 3:
            cout << "You entered 3." << endl;
            break;
        default:
            cout << "You entered something else." << endl;
            break;
    }

    return 0;
}

Output

Enter a number: 5
You entered something else.

Problem 3: Breaking out of a nested loop

Write a program to exit a nested for loop early based on the value of a variable.

Run 
 
#include <iostream>
using namespace std;

int main() {
    int x;

    cout << "Enter a number: "; 
    cin >> x;

    for (int i = 1; i <= 10; ++i) {
        for (int j = 1; j <= 10; ++j) {
            if (i * j == x) {
                cout << "Found it!" << endl;
                break;
            }
        }
    }

    return 0;
}

Output:

Enter a number: 7
Found it!
Found it!

Implementation of Continue Statement in C++

Problem 1:

Write a program to print the series: 1,2,3,5,6,8,9,10
Run 
 
#include <iostream>
using namespace std;

int main()
{
    int i;
    for(i=1; i<=10; i++){
        if(i==4 || i==7) {
            continue;
        }
        else{
            printf("%d\n",i);
        }
    }
    return 0;
}

Output:

1
2
3
5
6
8
9
10

Problem 2:

Write a program to skip a segment of code if the number is even.
Run 
 
#include <iostream>
using namespace std;

int main ()
{
  int i = 0;
  while (i < 10)
    {
      if (i % 2 == 0)
	{
	  i++;
	  continue;
	}
      cout << i << endl;
      i++;
    }

  return 0;
}

Output:

1
3
5
7
9
