Hi,

Could you copy and paste the exact error massage that your compiler is telling you.

Try renaming your file from untitled2.c to untitled2.cpp instead. does it run ?

Your variable i is just in the scope of the first for loop on line 66:

for(int i = 0; i < 100; i++)

Try declaring i for the other loops. Instead of:

for (i = 0; i < nbS; i++)

try declaring int i for the other loop on line 71 and 80 also.

It does now compile thanks, however it doesn't do exactly what I expected... I was hoping it you could press a key for each role of the dice, instead it just runs the through all the moves

[tarmizi_adam2005]

Well then, maybe you would want to look back at your program logic.
