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,
Random number c++ in some range - Stack Overflow Possible Duplicate: Generate Random numbers uniformly over entire range I want to generate the random number in c++ with in some range let say i want to have number between 25 and 63 How can I hav
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++ - 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
c - Rand Implementation - Stack Overflow rand and srand are usually implemented as a simple LCG, you can easily write your own (it's few lines of code) without looking for the sources of rand and srand Notice that, if you need random numbers for "serious" purposes (e g cryptography), there are much better RNGs than LCG By the way, the C standard itself includes a sample implementation of rand and srand:
