Professor: How come the first and second call price are different? I used 100,000,000 paths. If it's because the random number generator, how come the first and second call price stay the same across runs? Thank you.

your compiler probably sets the seed to always be the same at the start of each run of the program.

Try using srand to set the seed before each call .
