Hi, my teacher wants me to have a function that will handle the generation of the required random values. The code works but I don't know exactly what he is talking about. Somewhere along the lines of randNum=rand()%(high-low)+low. Any help is much appreciated.

consider the <random> header (examples in ref section here) and <ctime> and <cstdlib> you are mixing C headers in.



hit=1+rand()%100;//Trying to get number 1 through 100
^^ success. this is a random number from 0-99 +1, which is 1-100.

If there is a problem, it isn't here.

however your srand (first statement in main) is rand not srand which is likely giving you the same numbers every time you run the code...

Thank you jonnin for helping. I did change the headers, but I had to keep the srand and had to change the generator parameters to balance the decimals in the calculations.
