3. Write a C++ program that can accept two inputs from user. First input being of character type (symbol to be displayed), and second input of integer type (length of one side of square). Then, the program prints a square pattern of the given character symbol as a square box with given length.

Write a C++ program that prompts the user to enter five test scores (decimal) then:• Prints the average of the scores.• Converts the average to an integer value. (Use a constant to store the number of scores).

Write a program (C++) to read the date and average from the temps.txt file. Use a string data type for the date and a doub e average. The program should then convert the average (Fahrenheit) to Celsius. The conversion formula is subtract 32 from the average (Fahrenheit) and then multiply by five and divide by nine, e. 32) * 5/9. Output the date, the average temperature (Fahrenheit) and the Celsius temperature to a file named celsi Use the manipulators you have learned about in this chapter to format the output as shown in the sample be low and print each number value to one decimal space. 1. Identify the following parameters to complete the specification above. Input parameters? Output parameters? Constant parameters? 2. Attach the input and output of a successful execution of your program below (Hint: Use the snipping tool to take screenshots):3. Run the program

Write a C++ program to read input a string containing uppercase alphabets and encode the string using the rules given below: • Replace 'B' with 5. Replace 'M' with 0. • Replace 'Y' with 4. Print the encoded string in the output.
