WebbThe rand ( ) function generates only random integers but you can get float random numbers by converting them to float. (float) (element) is an inbuilt method from C++ … WebbThe Solution is. Don't use srand inside the loop, use it only once, e.g. at the start of main (). And srand () is exactly how you reset this.
