Study Notes
C++ Code Explanation
- The given C++ code is used to generate random numbers between 1 and 100.
- The line
std::uniform_int_distribution dist(1, 100);indicates that a uniform distribution of integers is defined, which will generate numbers between 1 and 100. - The line
std::mt19937 gen(rd());initializes a Mersenne Twister random number generator, which is a high-quality random number generator, andrd()is used to seed the generator. - The purpose of the
forloop is to repeatedly generate random numbers using the Mersenne Twister generator and the uniform distribution, and print these numbers to the console.
