The code is as follows:#include The library cstdlib contains a random number generation function. The first statement within the loop of a program Srand (Time (NULL)) is to set the seed of a random number, the generation of random numbers requires a seed, and different seeds can generate a sequence of different 1 random numbers. If the user does not set a seed for a random number, the system specifies one. The system is the same for each program, each execution of the specified random number of
