Can anyone help me about this program

[Robertzzz]

Hello, everyone, I am new in learning C++. My professor assigns me to this. But I really have no ideas, please help. Thank you the one who help me.




Modify main() to generate ten values of d randomly in a for loop. d should be between 0 and 49.
