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.
[edit] Syntax attr-spec-seq(optional)continue ; 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:
