C++ Do/While Loop
C++ Do/While Loop
The do/while
loop is a variant of the while
loop. This loop will execute the code block once, before checking if the condition is true, then it will repeat the loop as long as the condition is true.
Syntax
do {
// code block to be executed
}
while (condition);
// code block to be executed
}
while (condition);
The example below uses a do/while
loop. The loop will always be executed at least once, even if the condition is false because the code block is executed before the condition is tested.
Example
#include <iostream>
using namespace std;int main() {
int i = 0;
do {
cout << i << "\n";
i++;
}
while (i < 5);
return 0;
}
Output:
