When we define an integer array, it is by default empty and does not contain any values initially. We will generate random numbers using the C++ library and then we will fill our array with these random numbers. The rand() Function in C++ The rand() function in C++ returns a pseudo-...

it can be utilized to fill arrays or matrices with arbitrary data for different purposes. In this example, the function generates a random integer between 0 andMAXnumber interval. Note that this function should be seeded withstd::srand(preferably passing the current time withstd::time(nullptr...
