Why only a little of array elements in the first, the code must be in writing cin> N? Dynamic memory distribution is not n is according to the running of the program?

CodePudding user response:

N value is uncertain, it is the memory unit of the existence of the original value, need to clear the assignment,

n value is uncertain, there is memory unit of the original value, need clear assignment,

Is must first determine the value of n, if you don't enter n value is to use sizeof function

CodePudding user response:

Write programs to use code control, of course, or n is any value,

CodePudding user response:

Under what circumstance are the function return value can be used as a left?

CodePudding user response:

What is the left value it? Even though?
