WebAug 24, 2024 · Output contains 5 random numbers in given range. C does not have an inbuilt function for generating a number in the range, but it does have rand function which generates a random number from 0 to RAND_MAX.

WebMar 23, 2024 · srand () function is an inbuilt function in C++ STL, which is defined in header file. srand () is used to initialize random number generators. The srand () function sets the starting point for producing a series of pseudo-random integers. If srand () is not called, the rand () seed is set as if srand (1) were called at the program start. WebDec 18, 2024 · The illustration above shows the problem. In the example, we intend to generate a random integer value in the range -1 to 1.
