what is meant that "do...while" loop is guaranteed to execute at least one time, in C++? Please someone should help me.

It will execute the statements written in the do { } clause no matter the condition is true or false. Then it will check the condition in the while( ) and repeat the loop if it is true. For example:
int x = 3;
do {
// some statements
}
while(x > 5);
This will execute the statements once, even considering that x is not greater than 5.

It means the code inside the while loop will always execute once before the condition to keep looping is checked.

it's do and while so it first does execute(do) and then the condition is used so it is guaranteed that it is executed whatever the case is
