Statements
Causes the remaining portion of the enclosing for, range-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.

[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, range-for, while, and do-while loops).
More precisely,
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 and range-for loop, it acts as:
for (/* ... */) { // ... continue; // acts as goto contin; // ... contin:; }

[edit] Example
Run this code
#include <iostream> int main() { for (int i = 0; i < 10; ++i) { if (i != 5) continue; std::cout << i << ' '; // this statement is skipped each time i != 5 } std::cout << '\n'; for (int j = 0; 2 != j; ++j) for (int k = 0; k < 5; ++k) // only this loop is affected by continue { if (k == 3) continue; // this statement is skipped each time k == 3: std::cout << '(' << j << ',' << k << ") "; } std::cout << '\n'; }
Output:
5 (0,0) (0,1) (0,2) (0,4) (1,0) (1,1) (1,2) (1,4)
