Q1. a) The Little Man Computer (LMC) is an instructional model of a computer used to teach students all of the basic features of a modern computer in a simplified way. The following Little Man program is supposed to add two input numbers and output the result, i.e.,
OUT = IN1 + IN2

i) Change the program above to add the numbers 157 and 13. (Hint: these numbers are constants and therefore can pre-exist into memory before the execution of the program). No need to write both mnemonics and numeric codes (opcodes), either one is fine. Please refer to the instruction set provided for all the LMC instruction mnemonics and opcodes.
Exercise 4: Selection and loop statements
A certain professor gives 5-point quizzes that are graded on the scale 5-A, 4-B, 3-C, 2-D, 1-
F, 0-F. Write a program that accepts a quiz score as an input and prints out the corresponding
grade.
The input data must be a float numbers and between 0 and 5
Example
Input :
Quiz score: 3
Output:
The grade is C.
Exercise 4
Write an improved version of the future value program from Chapter 2. Your program will
prompt the user for the amount of the investment, the annualized interest rate, and the number
of years of the investment. The program will then output a nicely formatted table that tracks
the value of the investment year by year. Your output might look something like this:

For example, Figure 7.21 shows a magic square in which N=3, and the sum of the rows, columns, and diagonals is 15. Write a program that constructs and displays a magic square for a given odd number N. This is the algorithm:arrow_forward4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }arrow_forward
