7. Comparing Charactersby CodeChum Admin
Most, if not all things have numeric values. That goes for characters too. In order to find out which character has a higher value, we have to compare them with each other and display the value of the higher character.
Instructions:
In the code editor, you are provided with a main() function that asks the user for 2 characters, passes these characters to a function call of the getHigherValue() function, and then prints out the ASCII value of the higher character.Your task is to implement the getHigherValue function which has the following details:Return type - intName - getHigherValueParameters - 2 characters to be comparedDescription - the ASCII value of the higher character.Hint: Comparing characters in C is just like comparing integers.DO NOT EDIT ANYTHING IN THE MAINInput
1. First character
2. Second character
Output
Enter first character: aEnter second character: hResult value = 104
(C++ Programming language)
There are following two major issues associated with cpp programs:• When a program is terminated, the entire data is lost. • If you have to enter a large number of data, it will take a lot of time to enter them all in the different programs.Suggest a solution and elaborate the same with the help of suitable examples.
(25 min) The following table shows the foreign exchange rates for a few currencies.
Foreign Currency
RM
USD (D)
1 Dollar
4.16
GBP (P)
1 Pound
5.68
KRW (W)
1000 Won
3.51
JPY (Y)
100 Yen
3.69
Develop a complete C++ program that will prompt the user to enter the currency preferred and the amount required. The
program should include a function with the following prototype:
double CurrencyBuy(char, double):
The first parameter in the function prototype is for the type of currency where the characters D, P, W and Y represent
Dollar, Pound, Won and Yen respectively. The second parameter is the amount to be bought. This function CurrencyBuy
should return, to the calling function, the payment to be paid in RM.
A sample of the output is given as follows.
Foreign Exchange Currency
Country Code
USD (D)
GВР (Р)
KRW (W)
JPY (Y)
Enter the country code: D
Enter the amount to be bought: 300
Payment due is RM 1248.

You are asked to write a program that computes each employee’s weekly pay and the average salary of all employees. The program then outputs the weekly pay of each employee, the average weekly pay, and the names of all the employees whose pay is greater than or equal to the average pay. If the number of hours worked in a week is more than 40, then the pay rate for the hours over 40 is 1.5 times the regular hourly rate. Use two parallel arrays: a one-dimensional array to store the names of all the employees (Name) a two-dimensional array of 10 rows and 3 columns to store the number of hours an employee worked in a week (Hrs Worked), the hourly pay rate (Pay Rate), and the weekly pay (Salary).

- 2. (Guess the Number) Write a C program that plays the game of "guess the number" as fol- lows: Your program chooses the number to be guessed by selecting an integer at random in the range 1 to 1000. The program then types: 5.32 I have a number between 1 and 1000. Can you guess my number? Please type your first guess. The player then types a first guess. The program responds with one of the following: 1. Excellent! You guessed the number! Would you like to play again (y or n)? 2. Too low. Try again. 3. Too high. Try again. If the player's guess is incorrect, your program should loop until the player finally gets the number right. Your program should keep telling the player Too high or Too low to help the player “zero in" on the correct answer. [Note: The searching technique employed in this problem is called binary search.

In the game, there are different brief cases, each labeled with a number. Inside each brief case is an amount in Pesos and the goal is to guess which briefcase contains the smallest amount. In this program, instead of just finding the smallest amount, your task is to ask the user for an integer input and print the values in the array smaller than the inputted integer. Instructions: In the code editor, you are provided with an array with 100 elements.Your task is to ask the user for an integer input and then print all the elements in the array whose value is lesser than the inputted integer.Input 1.
