Generate random numbers following a normal distribution in C C++ C++11 C++11 offers std::normal_distribution, which is the way I would go today C or older C++ Here are some solutions in order of ascending complexity: Add 12 uniform random numbers from 0 to 1 and subtract 6 This will match mean and standard deviation of a normal variable An obvious drawback is that the range is limited to ±6 – unlike a true normal distribution The Box-Muller transform
