What is while loops?


while ( condition ) { Code to execute while the condition is true } The true represents a boolean expression which could be x == 1 or while ( x != 7 ) (x does not equal 7). It can be any combination of boolean statements that are legal. Even, (while x ==5 || v == 7) which says execute the code while x equals five or while v equals 7. Notice that a while loop is the same as a for loop without the initialization and update sections. However, an empty condition is not legal for a while loop as it is with a for loop.


using namespace std; // So we can see cout and endl

int main()
int x = 0; // Don't forget to declare variables

while ( x < 10 ) { // While x is less than 10
cout<< x < x++; // Update x so the condition can be met eventually
