How does the code playground compile and execute code ? All in a single second or segmented

The main reason l am putting this question out here is that my code that lam working on is using the srand , rand and time functions to generate random numbers for variables in my code and i have been getting very weird results back. For example i have two arrays that the code fills with numbers between 1 and 4 in the first and 1 and 10 in the second. In every situation i was getting the same result, in this case 4/2. I am wondering if this because of my code or its just how the compiler has to work.

Probably not the compiler, or indirectly, but as execution of the compiled code is done in a special way ( as for input/output is some buffering stuff ), it may occurs others particularities... Unfortunatly, I'm afraid that we may do ourselves tests to discover where and how are limitations ^^

fair enough , i was findinh the input and output using c++ in the code playground weird. was also having some problems when declaring a class and it used rand functionality , so i think the rand function can only really used to make a single random number per statement in the code in c++.
