C++ continue statement

The continue statement is a control structure in C++ that allows you to skip the current iteration of a loop and move directly to the next iteration. The continue statement can be used in conjunction with for, while, and do...while loops to skip a specific iteration when a specific condition is met. The basic syntax of the continue statement is as follows:

1continue;

The continue statement must be placed inside the loop and can be used to skip the current iteration of the loop when a specific condition is met.

Let's take a look at two examples of the continue statement in C++ and their output:

Example 1: Simple continue Statement

1#include <iostream>
2using namespace std;
3
4int main()
5{
6   for (int i = 1; i <= 5; i++)
7   {
8      if (i == 2)
9      {
10         continue;
11      }
12      cout << "Value of i: " << i << endl;
13   }
14
15   return 0;
16}

In the above example, the continue statement is used inside the for loop to skip the current iteration of the loop when the value of i is equal to 2. The for loop initializes the value of i to 1 and continues to execute as long as i is less than or equal to 5. The continue statement is executed when the value of i is equal to 2, which skips the current iteration of the loop and continues with the next iteration. The output will be:

1Value of i: 1
2Value of i: 3
3Value of i: 4
4Value of i: 5

Example 2: Nested continue Statement

1#include <iostream>
2using namespace std;
3
4int main()
5{
6   for (int i = 1; i <= 3; i++)
7   {
8      for (int j = 1; j <= 2; j++)
9      {
10         if (i == 2 && j == 1)
11         {
12            continue;
13         }
14         cout << "Value of i: " << i << " and j: " << j << endl;
15      }
16   }
17
18   return 0;
19}

In the above example, the continue statement is used inside a nested for loop to skip the current iteration of the inner loop when the value of i is equal to 2 and the value of j is equal to 1. The outer for loop initializes the value of i to 1 and continues to execute as long as i is less than or equal to 3. The inner for loop initializes the value of j to 1 and continues to execute as long as j is less than or equal to 2. The continue statement is executed when the value of i is equal to 2 and the value of j is equal to 1, which skips the current iteration of the inner loop and continues with the next iteration of the inner loop. The output will be:

1Value of i: 1 and j: 1
2Value of i: 1 and j: 2
3Value of i: 2 and j: 2
4Value of i: 3 and j: 1
5Value of i: 3 and j: 2
