Getting 2 inputs from user in Code playground.

Question

I was testing the code in C++ course that encountered a problem. The program takes 2 input and then print them to cout. When I submit only one integer, the second one will be '8'. And when I submit no input the first one will be '0' and second one again '8'. Is their any default value rule or they are just garbage?

Answer 1

Initialize the variables, otherwise you risk having garbage value.

int a {0}, b {0};

I can't explain the reason behind the value for variable <b> which always be 8 while being uninitialized, but in the following discussion you can find good explanation of how variables value are initialized:
