Currently, the program produces random numbers between 0 and 100. However, the program requirements state that these random numbers must be between 0 and RAND_MAX. Fortunately, rand() generates numbers between 0 and RAND_MAX by default, so you only need to remove the modulo operation in the source.

For example, instead of this:

bufferItem item = rand() % 100;

Do this:

bufferItem item = rand();

Sometimes, when executing the program, two or more producer/consumer threads will try to print output at the same time. This happens more frequently for smaller THREAD_MAX_SLEEP_TIME values; try setting it to 1 to see what I mean.

produce 18
produce 66
consume 18
consume 66
produce 15
produce consume 515

consume 5
produce 75
consume produce 7588

produce 94
consume 88
produce 38
consume 94

This behavior occurs intermittently and is obviously undesired.
