WebTo get a different series of random numbers each time the program is run, the time that the program is run can be passed as the seed value for the random number generator. This is done as follows: srand (time (0)); If the time function is used, make sure to include the ctime library as well. Websrand allows you to start with different starting points, allowing the random number generator to seem more random. srand must only be used once or the random number generator may not be random. In order to assure a different sequence of random numbers we use seed srand with time (0) found in ctime. #include #include WebNote: The asctime() and ctime() functions, and other time functions can use a common, statically allocated buffer to hold the return string.

WebFeb 20, 2024 · time () function in C. The time () function is defined in time.h (ctime in C++) header file. This function returns the time since 00:00:00 UTC, January 1, 1970 (Unix timestamp) in seconds. If second is not a null pointer, the returned value is also stored in the object pointed to by second. Websrand () is used to seed the random number generator (and only needs to be called once, best to do this at the start of main ()). The seed value could be obtained from user input, but usually the best way is to use the time value obtained from the computer's clock, since that will change frequently (like between runs of the program)
