In this article, I will take you through a C++ program to generate random numbers.
C++ Program to Generate Random Numbers
Random Numbers 55 Three random numbers :218 9057 20727
Understanding The Above Code:
You can also write functions that perform a certain action but do not return a value to the function that called them. The void type is available for functions of this type, also called procedures in other programming languages. For example, void srand( unsigned int seed );
The standard srand() function initializes an algorithm that generates random numbers. As the function does not return any value, then it is of type void. An unsigned value is passed to the function as an argument to prime the random number generator which is used to create a series of random numbers.
If a function does not expect an argument, the function prototype must be declared empty or the braces following the function name must be left empty. For example, int rand( void ); // or int rand();
The standard rand() function is called without any arguments and returns a random number between 0 and 32767 which returns a series of random numbers by repeating the function call.
Function prototypes for srand() and rand() are in the cstdlib and stdlib.h header files. Calling the rand () function without having previously called srand() creates the same sequence of numbers as if the following statement had been executed: srand(1);
If you want to avoid generating the same sequence of random numbers each time the program is run, you must call srand() with a different value for the argument each time the program is run.
At last, it is very common to use the current time to initialize and generate a random number. I hope you liked this article on how to create a C++ program to generate random numbers. Feel free to ask your valuable questions in the comments section below.
