hi all,
i need to know how to generate a number..influenced by percentages..
how do u write code ...so for example, there is a 95% chance that a variable = 1 and the other 5% of the time it equals 0...
right now i got
#include <cstdio>
int random = rand () % 2;
but this is randomly giving me 1 or 0...
thanks.
Well for a percentage, you need rand() % 100
So to get to where you want to be
int random = rand() % 100 > 95 ? 1 : 0;
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Why do more people use rand than.Code:random(int);
Because rand() is a standard function, and random() isn't

Hi, just a follow up question to this thread. So how would you write the code if you have 3 numbers, for example, 60% probability of generating 0, 35% generating 1 and 5% generating 2. Thanks a lot
Code:int random = rand()%100; int result; if(random < 60) result = 0; else if(random >= 60 && < 95) result = 1; else result = 2;
