Continue Statement with Nested Loops
Using continue, you skip the current iteration of the inner loop when using nested loops.
Example:
C++
// C++ program to explain the use // of continue statement with nested loops #include <iostream> using namespace std; int main() { for (int i = 1; i <= 2; i++) { for (int j = 0; j <= 4; j++) { if (j == 2) { continue; } cout << j << " "; } cout << endl; } return 0; } |
0 1 3 4 0 1 3 4
Continue skips the current iteration of the inner loop when it executes in the above program. As a result, the program is controlled by the inner loop update expression. In this way, 2 is never displayed in the output.
continue Statement in C++
C++ continue statement is a loop control statement that forces the program control to execute the next iteration of the loop. As a result, the code inside the loop following the continue statement will be skipped and the next iteration of the loop will begin.
Syntax:
continue;
Flowchart of continue Statement in C++
Example: Consider the situation when you need to write a program that prints numbers from 1 to 10 but not 4. It is specified that you have to do this using loop and only one loop is allowed to use. Here comes the usage of the continue statement. What we can do here is we can run a loop from 1 to 10 and every time we have to compare the value of the iterator with 4. If it is equal to 4 we will use the continue statement to continue to the next iteration without printing anything otherwise we will print the value.
