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,

clarification for RAND_MAX and rand () in c stdlib. h 10 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) Use %d and you'll see the actual value of RAND_MAX By the way, pretty much any decent compiler will warn you about that invalid printf if you crank the warnings high enough
c++ - How does modulus and rand () work? - Stack Overflow 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 random number between 1 and 10 in c - Stack Overflow randomnumber = rand() % 10; printf("%d\n", randomnumber); return 0; } This is a simple program where randomnumber is an uninitialized int variable that is meant to be printed as a random number between 1 and 10 However, it always prints the same number whenever I run over and over again Can somebody please help and tell me why this is happening?
