Random c++

Question

hello, i got 2 questions

1. is there a "random" function in c++

2. how i get a random value from 3 numbers(1,4,2)

Answer 1

Cat Sauce to get random value from 1,2 and 4; you can declare this in an array... generate random number for rand()%3 which would give you number as 0,1 or 2 randomly... use this as index of array to get number which would give you random number from array

Answer 2

Yes,
v1 = rand() % 100; // v1 in the range 0 to 99
v2 = rand() % 100 + 1; // v2 in the range 1 to 100
v3 = rand() % 30 + 1985; // v3 in the range 1985-2014

You can see more details from this link,

Answer 3

Cat Sauce,
The standard formula should be like this,
rand() % (max + 1 - min) + min

Good Luck~

Answer 4

Uchiha Itachi i found this way

min = minumum number
max = maximum number

(rand() % (max - min)) + (min + 1)

if min = 20 and max = 50

then the range is 20-50
