- How to generate a random int in C? - Stack Overflow
Many implementations of rand() cycle through a short list of numbers, and the low bits have shorter cycles The way that some programs call rand() is awful, and calculating a good seed to pass to srand() is hard The best way to generate random numbers in C is to use a third-party library like OpenSSL For example,

printf("%d\n", rand() % 50); Where is the connection between rand and srand? What I mean or expect is I assume rand () will get some parameter from srand () so it knows to generate different numbers each time I assume it would look something like rand (srand (time (null)); It's like initializing a variable without using it to me srand is being initialized, but I don't see it being used Does
- Generate a value between 0. 0 and 1. 0 using rand () - Stack Overflow
The OP's reasoning for trying it was wrong, but had this been necessary, the UB could've been avoided by adding 1 0 instead of 1, which would coerce RAND_MAX to double type and so avoid the integer overflow

C++11 gives you a lot of new options with random The canonical paper on this topic would be N3551, Random Number Generation in C++11 To see why using rand() can be problematic see the rand () Considered Harmful presentation material by Stephan T Lavavej given during the GoingNative 2013 event The slides are in the comments but here is a direct link I also cover boost as well as using rand

A second lesson is that this shows another way in which <random> is easier to use than rand() and manually computing your own distributions The built-in uniform_int_distribution allows you to directly state the desired, inclusive range
