Random Number Qt MacOs

[Daniela]

Hello!


I'm doing a random number in MacOs, but it returns always the same number. i use this:


#include <ctime> // To seed random generator

// Randomize
qsrand( time(0) );

//to get a random number i use this funtion:

int myClasse::randInt( int a, int b )
{
qsrand( time(0) );
return a + rand() % ( b - a + 1 );
}

but it always return the same number. Why this happens?


Thanks for read this post...

Now i "reset" the qsrand, and for any time i start my application, the random number is not the last one. Thats ok.

But in the same time the application is running, if i want to get a new Random number several times, it returns always the same number.

How can i random the random number process to return always different numbers?
Is it possible?

Hi,

You have to call "srand" only the first time that your application starts. Then every call to "rand" will get you different random values.
