I just need some help with these questions. C++, thanks in advanced!

1. Assume that ip has been declared to be a pointer to int and that enrollment has been declared to be an array of 20 elements.

Write a statement that makes ip point to the first element in the array.

2. Declare a char array named line suitable for storing C-strings as large as 50 characters, and write a statement that reads in the next line of standard input into this array. (Assume no line of input is 50 or more characters.)

3. Assume that name is a variable of type string that has been assigned a value. Write an expression whose value is the last character of the value of name. So if the value of name were "Blair" the expression's value would be 'r'.
