Include rand c++
WebNow, assuming you obtained integers in the range from 0 to RAND_MAX - 1 (inclusively) by using std::rand () % RAND_MAX, the chance of getting a 0 would now be doubled, since it will be the result when std::rand () returns either 0 or RAND_MAX. Any other number will only be obtained when directly returned by std::rand (). WebApr 27, 2024 · C/C++ #include directive with Examples - GeeksforGeeks A Computer Science portal for geeks.
