continue statement - cppreference.com (original) (raw)

Causes the remaining portion of the enclosing for, while or do-while loop body to be skipped.

Used when it is otherwise awkward to ignore the remaining portion of the loop using conditional statements.

attr-spec-seq	-	(C23)optional list of attributes, applied to the continue statement

[edit] Explanation

The continue statement causes a jump, as if by goto, to the end of the loop body (it may only appear within the loop body of for, while, and do-while loops).

For while loop, it acts as

while (/* ... */) { // ... continue; // acts as goto contin; // ... contin:; }

For do-while loop, it acts as:

do { // ... continue; // acts as goto contin; // ... contin:; } while (/* ... */);

For for loop, it acts as:

for (/* ... */) { // ... continue; // acts as goto contin; // ... contin:; }

[edit] Example

#include <stdio.h> int main(void) { for (int i = 0; i < 10; i++) { if (i != 5) continue; printf("%d ", i); // this statement is skipped each time i != 5 } printf("\n"); for (int j = 0; j < 2; j++) { for (int k = 0; k < 5; k++) { // only this loop is affected by continue if (k == 3) continue; printf("%d%d ", j, k); // this statement is skipped each time k == 3 } } }

Output:

5 00 01 02 04 10 11 12 14
