CProgrammingServer Side Programming rand() The function rand() is used to generate the pseudo random number. It returns an integer value and its range is from 0 to rand_max i.e 32767. Here is the syntax of rand() in C language, int rand(void); Here is an example of rand() in C...

X = rand returns a random scalar drawn from the uniform distribution in the interval (0,1). X = rand(n) returns an n-by-n matrix of uniformly distributed random numbers. example X = rand(sz1,...,szN) returns an sz1-by-...-by-szN array of random numbers where sz1,...,szN ...
