UCO Write a Program Initializing an Array with Ten Integers Project – Description
E5.2 Write a c++ function that computes the balance of a bank account with a given initial balance and interest rate, after a given number of years. Assume interest is compounded yearly.
E5.6 Write a c++ function
String middle(string str)
that returns a string containing the middle character in str if the length of the str is odd, or the two middle characters if the length is even. For example, middle(“middle”) returns “dd”.
E5.11 Write functions
double sphere_volume(double r)
double sphere_surface(double r)
double cylinder_volume(double r, double h)
double cylinder_surface(double r, double h)
double cone_volume(double r, double h)
double cone_surface(double r, double h)
that compute the volume and surface area of a sphere with radius r, a cylinder with a circular base with radius r and height h, and a cone with a circular base with radius r and height h. Then write a program that prompts the user for the values of r and h, calls the six functions, and prints the results.
E5.14 Write a c++ function void sort2(int& a, int& b) that swaps the values of a and b if a is greater than b and otherwise leaves a and b unchanged. For example,
int u = 2;
int v = 3;
int w = 4;
int x =1;
sort2(u, v); // u is still 2, v is still 3
sort2(w, v); // w is now 1, x is now 4
E5.17 Implement the number_to_grade function of Worked Example 5.3, so that you use two sets of branches: one to determine whether the grade should be A,B,C,D, or F, and another to determine where a+ or – should be appended.
E5.18 Write a c++ program that prints instructions to get coffee, asking the user for input whenever a decision needs to be made. Decompose each task into a function, for example:
Void brew_coffee()
{
cout
