Do While Loop

It is a bottom tested loop. This loop first goes inside the loop and then checks the expression so if the expression is not true then the loop will executes at least once.
  Statement 1;
  Statement 2;
  Statement n;
while (test expression);


void main()
  char a;
    cout<<"Want to continue?\n";
    cout<<"Press Y\n";

Explanation of the program
The control comes inside the loop and prints the message then takes the input with the input function. Then the loop checks the expression. Suppose we entered Y, then the loop will check its expression and found that it is true so the loop will again be execute and will give message to the user for input and the loop will break when the user will enter any other value.
