continue statement
From cppreference.com
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)
