C++ home work ________________________________ 1a) int addition (int a, int b) { int r; r=a+b; } 

What is wrong with this function?

The parameter list is wrong

The variable definition is wrong

The calculation is wrong

Something is missing

_______________________________

2b)You wish to determine whether the contents of var1 and var2 are not equal. What is missing?

if(var1 _____ var2)

4)

Which would you use to get an unknown number of values entered by a user?

loop

else statement

case statement

if statement

Which type of variable is total and what is it used for?

void countUp() { int total = 0; for (int i = 0; i < 100; i++) { std::cout << i<< std::endl; total = total + i; }

5c)

Which type of variable is total and what is it used for?

void countUp() { int total = 0; for (int i = 0; i < 100; i++) { std::cout << i<< std::endl; total = total + i; }

a)	A counter variable. It is used to determine the number of times the loop will repeat.

b) An accumulator variable. It is used to store the sum of all i values

6)

Consider the following code. Why would you get identifier not found errors?

int main()

{ int num1 = 1; int num2 = 2; int total = 0; std::cout << "total = " << total << std::endl; total = addition(num1, num2); std::cout << "After addition(num1, num2), total = " << total << std::endl; }

int addition (int a, int b) { int r; r = a + b; return r; }

a)	Because variable a is not defined in the body of the even and odd functions.

b)	Because the function call does not match the function definition.

c)	Because the function is not declared prior to the function call. Their prototype is needed above main.

d)	Because the variable i is not initialized to a valid integer value before it is used.
