Generate random values with fixed sum in C++ [closed]

Answer 1

You can generate n values defined by this : ((Sum - sumOfGeneratedValues) / n - (numberOfGeneatedValue)) -+X (With X maximal deviance)

Example :

SUM = 100 N = 5 +- 10

---

Rand between 100 - 0 / 5 - 0 --> 20 +-10 (So bewteen 10 and 30)

Value1 = 17;

Rand between 100 - 17 / 5 - 1 ---> 21 +-10 (So between 11 and 31)

... etc

Deviance would make your random uniform :)
