Variable names in C, generically called identifiers, use the underscore character to mash together words to make useful names. This is called snake case. For example,
double city_sales_tax = 0.08;
int days_in_year_2018 = 365;
char superman_letter = ‘s’;
char *mothers_maden_name = “Smith”;
Another way to do this is to omit the underscore but to capitalize the first letter of each word in the identifier, except for the first word. This is called camel case. For example,
double citySalesTax = 0.08;
int daysInYear2018 = 365;
char supermanLetter = ‘s’;
char *mothers_maden_name = “Smith”;
These are called naming conventions.
In general, you can use either in your programs, BUT you need to constantly use one or the other in your code, and avoid mixing the 2 in the same program.
Which one makes the most sense to you, and why?
Topic: Function with default argument value covered in Chapter 6
Write a C++
Do not use any topic not covered in lecture. There is no need for use of loop, and needs the use of only an "if/else" statement.
Write exactly these 3 functions: power(x,y), print(text, number) function and the main() function. The power(x,y) function returns an integer result that is calculated by raising a number x (integer) to a power y (integer). The second argument y (exponent) of the function can not exceed 100.If the second argument exceeds 100, the function should return -1.
Your power(x,y) function must be able to take either 1 or 2 integer arguments using the concept of default argument in chapter 6. Look at the main() code to deduct what the default value should be.
You should call C++ pow(x,y) function in the "cmath" library in the body of your power(x,y) function to avoid doing the power calculation yourself.
The print(text, number) function is the only one that does output to the console using…
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.

- Number guessing Game Write a C program that implements the “guess my number” game. The computer chooses a random number using the following random generator function srand(time(NULL)); int r = rand() % 100 + 1; that creates a random number between 1 and 100 and puts it in the variable r. (Note that you have to include <time.h>) Then it asks the user to make a guess. Each time the user makes a guess, the program tells the user if the entered number is larger or smaller than its number. The user then keeps guessing till he/she finds the number. If the user doesn’t find the number after 10 guesses, a proper game over message will be shown and the actual guess is revealed. If the user makes a correct guess in its allowed 10 guesses, then a proper message will be shown and the number of guesses the user made to get the correct answer is also printed. After each correct guess or game over, the user decides to play again or quit and based on the user choice, the computer will make…arrow_forwardint fun(int k){ return ( ); void main(){ int n; cin >> n; n = n * fun(n); <-- 1 Fill in the appropriate statement and expression in fun, so that when it is called in main, and after the execution of the statement marked 1, the value of n would always be n3.arrow_forwardstruct date{ int day; int month; int year; }; Write a function named void increaseDay(struct date *d) that increases the value of a variable of struct date type with integer year, month, and day members by one day.

A value returning function executes its statements and then returns a value. true or false Explain with details also explain wrong optionarrow_forwardC++ Programming Problem: To make telephone numbers easier to remember, some companies use letters to show their telephone number. For example, using letters, the telephone number 438-5626 can be shown as GET LOAN. In some cases, to make a telephone number meaningful, companies might use more than seven letters. For example, 255-5466 can be displayed as CALL HOME, which uses eight letters. Write a program that prompts the user to enter a telephone number expressed in letters and outputs the corresponding telephone number in digits. If the user enters more than seven letters, then process only the first seven letters. Also output the hyphen after the third digit. Allow the user to use both uppercase and lowercase letters as well as spaces between words. Moreover, your program should process as many telephone numbers as the user wants.arrow_forwardC++ 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 daysarrow_forward
