Truly random number - If srand won't generate duplicate number, what happen if the range of random number finish generated?

If 1+rand()%6 gives 1-6, does it mean after it generates 6 times the program will halt or reset the pool and generate again?

No. The output of rand and the modulo are two separate things. rand will only start to give the same numbers after 2^32 times.

I know but is there a way to achieve truly random number without using mt19937 and array+rand?
