C++

Just getting into C++ I'm experimenting with random number generator  

How is it that I would sometimes get the same number?

srand(time(0)); 

I have int as 

int randNumb1 = 0;

int randNumb2 =0;

so it do this

randNumb1 = (rand() % 20) +1;

cout << "First Random number is  " <<  randNumb1 << endl;;

    randNumb2 = (rand() % 20) +1;
    while (randNumb1 = randNumb2) {
    
            randNumb2 = (rand() %20) +1;
        cout << "Second number  is     " << randNumb2 << endl;;
        // terminate the loop
        break;
    }

I'm not sure if you intended to use the assignment operator on this line:

while (randNumb1 = randNumb2) {

You probably want the == comparison operator.

You shouldn't need to break that loop, either. The cout statement should be outside the loop after the loop has finished.

when I place the == comparison operator and comment out the break instead of = it only displays 1 number

does not show second number

That is because you have the cout statement inside the while loop. Take it out of the loop and put it further down in the code.
