    15. What is the output of the following statements? Suppose a and b are int variables, c is a double variable, and a = 13, b = 5, and c = 17.5.

    a. cout <<a + b - c << endl; = 0.5
    b. cout << 15 / 2 + c << endl; = 25
    c. cout << a / static_cast<double>(b) + 2 * c << endl; = 37
    d. cout << 14 % 3 + 6.3 + b / a << endl; = 8.6846153
    e. cout << static_cast<int>(c) % 5 + a - b << endl; = 11
    f. cout << 13.5 / 2 + 4.0 * 3.5 + 18 << endl; = 33.75

    Would you please check my work to see if I did this correct. Thanks a lot!

    #include <iostream.h>
    int main(){
    int a,b;
    double c;
    a=13;
    b=5;
    c=17.5;
    cout << a<< endl;// != 0.5
    // a = 13, if you didn't miss something

    cout << 15 / 2 + c << endl;// != 25
    //15/2 = 7 (integer division) + 17.5 = 24.5

    /*
    lets look at an example using static_cast<>()

    #include <iostream>
    using namespace std;

    int main() {
    int j = 41;
    int v = 4;
    float m = j/v;
    float d = ...
