Pseudo Random Number Generator

This simple C/C++ header file generates random numbers using the linear congruential method. It also includes a function to set the initial seed based on the number of CPU cycles.

Usage

Include the header file in your project and call the rand() or rand_range(min, max) functions to use random numbers.

#include "pseudo_random.h"
#include <stdio.h>

int main() {
    // Set the seed to generate random numbers
    srand(123); // Example seed

    // Example: Generate a random number between 1 and 10
    int random_number = rand_range(1, 10);
    printf("Random number: %d\n", random_number);

    return 0;
}

Functions

• void srand(unsigned int c_seed): Used to set the seed of the random number generator.
• int rand(): Returns a random integer.
• int rand_range(int min, int max): Returns a random integer within a specific range (including min and max).
• void random_seed_by_cpu_cycle(): Sets a random seed based on the number of CPU cycles.

Note

This random number generator is suitable for simple applications but is not appropriate for security or cryptographic applications. More secure random number generators should be preferred.
