Srand

Question

is it possible to get random numbers of certain intervals. say I want a random number between 0-100 of 10s?

Answer 1

Number greater than 25, less than (or equals to?) 100 and multiple of 10.

int rand_num = 30 + ((rand() % 8) * 10);

Answer 2

srand(time(0));

int rand_num = (rand() % 11) * 10;

// This would give you 0 to 100 with intervals of 10. It is easy if you understand the math behind it.

Answer 3

yep that makes sense. thanks

Answer 4

actually yeah. so that works for multiples of 10 such as 100 or 50 but what if I actually want a number greater than 25 less than 100 and multiple of 10. I thought 100-((rand()%2.5)*10) but that could only give you 90 or 80.

Answer 5

what about this. what if I want a random number between 0 and 50 in multiples of 10

Answer 6

nvmd I see it now
