C++ Programming Structure - Simple Explanation
Definition
In C++, a do while loop, sometimes just called a do loop, is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition.
Syntax
do {
Code to execute while the condition is true
} while ( condition );Example Program

using namespace std;
int main() {
// Variable Declaration
int a;
// Get Input Value
cout << "Enter the Number :";
cin>>a;
int counter = 1;
//Do while Loop Block
do {
cout << "Execute Do While " << counter << " time" << endl;
counter++;
} while (counter <= a);
// Wait For Output Screen
getch();
return 0;
