1. (6pts) Assume the following variables are defined:

int age;

double pay;

char section;

Write a single cin statement that will read input into each of these variables.

2. (8pts) Write C++ program expressions for the following algebraic expression:

a = 10x

z = 3x + 8y + 17k

y = ³

g = +16 / 8

c = ⁴ / ²³

3. (6pts) Rewrite the following variable definition so that the variable is a named constantint

int PayRate;

4. (6pts) Write a multiple assignment statement that can be used instead of the following group of assignment statement:

front = 1;

back = 1;

left = 1;

right = 1;

5. (8pts) In C++, list three type casting methods to convert a character to an integer.

6. (6pts) Which one of following statement is equivalent to num /= a + 5 ?

a. num = num / a + 5;

b. num = num / (a + 5);

c. num = / a + 5;

7. (8pts) List two methods to store a single character being read from the user input, assume variable name is ch.

8. (8pts) What is difference between overflow and underflow? List two potential results when floating-point variables overflow or underflow.

Find the error and modify
