The purpose of the rand() function in C language is to generate a pseudo-random number. Pseudo-random numbers appear random but are actually generated based on a certain algorithm using an initial seed value. The random function can be used to simulate random events, generate random number sequences, etc. Common applications include:
- Game development: randomly generating enemy positions, dropped items, etc.
- Encrypting data increases the security of passwords by acting as a key generator.
- Simulation experiments are used to generate random input data in order to test the performance and stability of algorithms.
- Lottery/Random selection: used for picking lucky users, randomly selecting candidates, etc.
It is important to note that the numbers generated by random functions are pseudo-random, meaning they are somewhat predictable. If highly secure random numbers are needed, specialized encryption libraries or hardware random number generators should be used.
