HELP PLEASE

Briefly describe the output of each small C++ program below. The output must be exact be especially careful regarding the type of data returned. (is in an integer? Is it a floating point number?)

Note: pay close attention to (d) and (f).

(a)	int x = 3; int y = 4; int x = 4; cout << x;	(b)	int x = 4; while (x < 5) x = x + 1; cout << x << endl;
(c)	int x = 3; double y = 3.0; if (x <= y) x = x + 2; cout << x << endl;	(d)	int tc = 0; int tf = 0; tf = (9/5) * tc + 32; cout << tf << endl;
(e)	int x = 0; while (x < 6) { if ((x % 2) == 0) cout << "even: " << x << endl; else { cout << "odd: " << x << endl; } x = x + 1; }
(f)	int x = 1; int i = 0; while (x <= 4) { x = x * i; i = i + 1; cout << x << endl; }
(g)	double multiply1(int num1, int num2 = 1, int num3 = 0); int main () { int number1 = 10; int number2 = 10; cout << multiply1(number1, number2) << endl; return 0; } double multiply1(int num1, int num2, int num3) { return num1*num2*num3; }
