Answer 1

Hello! I don’t understand what your code code is supposed to do but I can guess why you are getting random numbers. Normally when you get random big numbers is when you use a variable that wasn’t assigned a value. Like this...

int var;
cout << var; // will print out a random integer

Also I would recommend to make the variable names more descriptive than just x, a, b at the start of main

Answer 2

this code must sort the array, even numbers must go to the beginning, then odd numbers.
