- 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,
- c - How does srand relate to rand function? - Stack Overflow
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

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
- 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
- How do I generate a random number for each row in a T-SQL select?
I need a different random number for each row in my table The following seemingly obvious code uses the same random value for each row SELECT table_name, RAND() magic_number FROM information_s
- clarification for RAND_MAX and rand () in c stdlib. h
RAND_MAX is an integral constant, but you are printing it using the %f specifier (used for double), which is undefined behavior (and in your case happens to print 0)
