C++ While Loop
In C++, Thewhile
loop loops through a block of code as long the specified condition is met and equal to true
:C++ While Loop Syntax
while (condition) {
// code block to be executed while condition is met
}
Example of C++ While loop
#include <iostream>
using namespace std;
int main() {
int i = 0;
while (i < 3) {
cout << i << "\n";
i++;
}
return 0;
}
Output
0
1
2
1
2
In this example you can see that the loop will keep executing while
i
is less than value 3.Another example of C++ While loop
#include <iostream>
using namespace std;
int main() {
int i = 0;
while (i < 3) {
cout << "My index is: " << i << "\n";
i++;
}
return 0;
}
Output
My index is: 0
My index is: 1
My index is: 2
My index is: 1
My index is: 2
