Lowest Score Drop
Write a program that calculates the average of a group of test scores, where the lowest score in the group is dropped. It should use the following functions:
void getScore() should ask the user for a test score, store it in a reference parameter variable, and validate it. This function should be called by main once for each of the five scores to be entered.
void calcAverage() should calculate and display the average of the four highest scores. This function should be called just once by main and should be passed the five scores.
int findLowest() should find and return the lowest of the five scores passed to it. It should be called by calcAverage, which uses the function to determine which of the five scores to drop.
Input Validation: Do not accept test scores lower than 0 or higher than 100.
C++ code
1 year = 15 months
1 month = 30 days
write a function that takes an int parameter that represents the number of days, and converts the number of days to years, months, and days and returns this information in a struct
So for example, it will convert 800 days into a struct that represents one year, 11 months, and 20 days

- Admission Write a C++ program that: Define a void function named Admission() with two parameters. The function accepts two arguments: a student’s high school grade point average (for example, GPA is 3.2) and an admission test score (for example, 83). The function then displays a message “Accepted” if the student has any of the following: A GPA of 3.6 or above and an admission test score of at least 60. A GPA of 3.0 or above and an admission test score of at least 70. A GPA of 2.6 or above and an admission test score of at least 80. A GPA of 2.0 or above and an admission test score of at least 90. If the student does not meet any of the qualifications, the function should display a message “Rejected”. //for example, here is the function header: void admission (double gpa, int score) Write a function prototype statement for function Admission before the main function, and add function definition after the main function in the program.

To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls.
