How to use XORShift algorithm to generate 96-bit random numbers. After run the application, each time I press "Start Button" it returns a different 96-bit number.
Code for XORShift algorithm:
unsigned long xor()
{
static unsigned long y=2463534242;
yˆ=(y<<13); y=(y>>17);
return (yˆ=(y<<5));
}
This code is supposed to result in a different value for each run. Since y is static, it's value is initially 2463534242. But due to the static keyword, the value will remain in memory, until the program terminates (this is a bit of a simplified explanation, but it should do for this problem). So after the first run of the program, the value of y is the same as the result of xor(). This y is the initial value of y (the seed), when xor() is called for the next time, thus xor() produces a different value in the next run.
