it can be utilized to fill arrays or matrices with arbitrary data for different purposes. In this example, the function generates a random integer between 0 andMAXnumber interval. Note that this function should be seeded withstd::srand(preferably passing the current time withstd::time(nullptr...
In this code, we generate five random floating-point numbers within the specified range of 10 to 100 using the traditionalrandfunction. To ensure varied sequences, we seed the random number generator with the current time. Inside the loop, we calculate each random float value by combining the...
Edit & run on cpp.sh 9 is the random number 1 is the random number And another run: 9 is the random number 9 is the random number Generating numbers using lowest + std::rand() % highest gives a "proper" random number from the start. The bias in distribution is not being accounted...
