QRandomGenerator Bounded - C++

QRandomGenerator Bounded is a class provided by the Qt Framework that generates random numbers within a specified range. It is part of the QtCore module and can be used in any C++ project with Qt integration.

Usage

To use QRandomGenerator Bounded, first create an instance of the class by calling the constructor. Then call the bounded method with the lower and upper bounds of the desired range as parameters.

#include <QRandomGenerator>

QRandomGenerator rand_gen;  // create instance

int random_number = rand_gen.bounded(1, 10);  // generate number between 1 and 10

The bounded function returns a random number within the range specified, including both the lower and upper bounds.

Seed

By default, QRandomGenerator Bounded uses a system-generated seed value for generating random numbers. However, you can also use a custom seed and generate predictable sequences of random numbers.

#include <QRandomGenerator>

QRandomGenerator rand_gen(42);  // create instance with custom seed

int random_number = rand_gen.bounded(1, 10);  // generates the same random number every time

Conclusion

QRandomGenerator Bounded is a simple and efficient way to generate random numbers within a specified range for any C++ project with Qt integration. It is versatile enough to generate predictable sequences of random numbers or generate random numbers with a system-generated seed value.
