WebbC rand() The rand() function is defined in the stdlib.h header file. This function is used for Pseudo Random Number Generator(PRNG) within the range 0 to RAND_MAX. The RAND_MAX is a symbolic constant, depending on the C libraries its value greater but not less than 32767. Webbrand () in C. The method rand () in the C library returns a pseudo-random number in the range – 0 to RAND MAX (by default). RAND MAX is an implementation-dependent constant whose default value is guaranteed to be at least 32767. The rand () function accepts no parameters.

Webbrand () function This function basically generates random numbers every time it is called inside a program. In general, the range of the generated number is 0 to RAND_MAX.

WebbThe rand () function generates a pseudo-random integer in the range 0 to RAND_MAX (macro defined in ). Use the srand () function before calling rand () to set a starting point for the random number generator. If you do not call the srand () function first, the default seed is 1.

WebbDescription. The rand function returns a random number in the range 0 to +32767. The random number generator is reinitialized each time a non-zero value is passed in the seed argument. You may use the rand function to delay for a random number of clock cycles or to generate random data to feed into a particular algorithm or input routine. WebbWell, successive calls rand() just produce numbers that "look random". Now, rand() doesn't take a seed; that means that everytime the program runs, calls to rand() will generate the exact same sequence of numbers. This is a deliberate design decision; that means that the program behavior is reproducible (which can be important if you're debugging).
