c++ random number

#include <iostream>
#include <cstdlib>
#include <ctime>

int main() {
    // Seed the random number generator
    srand(static_cast<unsigned int>(time(nullptr)));

    // Generate a random number between 1 and 10
    int randomNumber = rand() % 10 + 1;

    // Output the random number
    std::cout << "Random number: " << randomNumber << std::endl;

    return 0;
}

1. #include <iostream>: Includes the input/output stream library.
2. #include <cstdlib>: Includes the C standard library for functions like rand() and srand().

3. #include <ctime>: Includes the C time library to use functions related to time.

4. int main() { ... }: The main function, the entry point of the program.

5. srand(static_cast<unsigned int>(time(nullptr)));: Seeds the random number generator by converting the current time (in seconds since Jan 1, 1970) to an unsigned integer and using it as the seed value for srand(). This step ensures a different seed each time the program runs.

6. int randomNumber = rand() % 10 + 1;: Generates a random number between 0 and 9 using rand() and % 10, then adds 1 to make the range 1 to 10.

7. std::cout << "Random number: " << randomNumber << std::endl;: Outputs the generated random number to the console.

8. return 0;: Indicates successful execution and termination of the program.
