Challenge 4: Custom Random Number Generator in C++

This is a solution for Challenge 4 in the Global Hack Week Beginner series, where I created a custom random number generator (RNG) using a Linear Congruential Generator (LCG) method in C++.

About the Challenge

The task was to create a random number generator using our own method in C++. I used the Linear Congruential Generator (LCG) to generate pseudo-random numbers. The random number generator was seeded with the current time (time(0)) to ensure randomness across different runs of the program.

Approach

The random number generation was implemented using the following formula:

[ X_{n+1} = (a \times X_n + c) \mod m ]

Where:

• a = 1103515245
• c = 12345
• m = 2^{31} - 1 (Maximum value for a 32-bit signed integer)

Steps Taken:

1. Implemented the LCG formula to generate random numbers.
2. Used time(0) to seed the random number generator.
3. Scaled the generated numbers to a user-defined range.
4. Displayed 10 random numbers as examples.
