float triangleArea(float, float);

Triangle area is given by A = 0.5bh where b is the base and h is the height of the triangle.

2. Write and test the following method that determines whether a given number is even. If it is even, return true, if it is odd, return false.

bool isEven(int);

3. Write and test the following method that accepts two integer parameters, i and j, and then returns the sum of the numbers from i to j.

int sum(int, int);

4. Write and test the following method that determines accepts an integer value n and returns the sum of the first n natural numbers. int sumN(int);

5. Write and test the following method that accepts an integer value n and displays n lines of 5 stars each.

void printNLines(int);
