The srand() function in C++ seeds the pseudo-random number generator used by the rand() function. It is defined in the cstdlib header file. Example #include<iostream> #include<cstdlib> using namespace std; int main() { // set seed to 10 srand(10); // generate random number int ...
The srand function sets the starting point for generating a series of pseudorandom integers in the current thread. To reinitialize the generator to create the same sequence of results, call the srand function and use the same seed argument again. Any other value for seed sets the generator to...

Therand() function returns a pseudo-random integer in the range 0 toRAND_MAXinclusive (i.e., the mathematical range [0,RAND_MAX]). Thesrand() function sets its argument as the seed for a new sequence of pseudo-random integers to be returned byrand(). These sequences are repeatable by...
The srand function sets the starting point for generating a series of pseudorandom integers in the current thread. To reinitialize the generator to create the same sequence of results, call the srand function and use the same seed argument again. Any other value for seed sets the generator to...
Sets the starting seed value for the pseudorandom number generator used by therandfunction. Syntax C voidsrand(unsignedintseed ); Parameters seed Seed for pseudorandom number generation Remarks Thesrandfunction sets the starting point for generating a series of pseudorandom integers in the current th...
In order to get reproducible behavior in a threaded application, this state must be made explicit; this can be done using the reentrant function rand_r(). Like rand(), rand_r() returns a pseudo-random integer in the range [0, RAND_MAX]. The seedp argument is a pointer to an ...
Edit & run on cpp.sh Apr 30, 2012 at 3:27pm Fewmets(6) I would use the random header but the header I have for it requires requires the new C++ standard to be enforced and I don't really want to do that. You're right in the fact that it's no more random than it is befor...
