I. Generating random numbers without a specified rangeWith the function rand (), the function prototype is int RAnd (), no parameters. A whole number between 0~rand_max is generated at this time. The size of the Rand_max can be viewed in the Include

Topic:1, a function fun () evenly returns 0 and 1, the probability of each is 50%, the use of this function to implement a function, so that the probability of return 1 is 3/4,0 probability of 1/4.2, if there is a function rand5 can equal the

Questions about random numbers in C Language It is important to use the rand function, srand function, and macro RAND_MAX (32767) to generate random numbers using C language. They are all declared in stdlib. h. Int rand (void); // generates a random
