[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
Run this code
#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
