Write a program that: Declare the following integer variables: Leftmotor Rightmotor Declare the following character arrays: lilac of size 50. - lea of size 30. Program 9 Repeat the steps below 10 times and then quit the program. Ask the user for a robot command and store it in a character array of size 50. Store the user input in lilac. The user input consist of up to two words inputted as one string. The motors are assigned values according to the string input and the table below. Also the input string could be one word or two words. If the first word is STOP then no further instruction is needed (no second word in the string). If the first word is move then a second word will follow First word Second word Left motor Right motor STOP 0 0 MOVE FORWARD 127 127 MOVE REVERSE -127 -127 MOVE MOVE LEFT RIGHT 64 127 127 64 The user input could be a mix of upper case and lower case letters so you need to change all the input to upper case before comparing with the instruction words.

In Chapter 4, you created a program that generates a random number, allows a user to guess it, and displays a message indicating whether the guess is too low, too high, or correct. Now, create a modified program called GuessingGame2 in which the user can continue to enter values until the correct guess is made. After the user guesses correctly, display the number of guesses made. Recall that you can generate a random number whose value is at least min and less than max using the following statements: Random ranNumber = new Random(); int randomNumber; randomNumber = ranNumber.Next(min, max);

(Computation) A magic square is a square of numbers with N rows and N columns, in which each integer value from 1 to (N * N) appears exactly once, and the sum of each column, each row, and each diagonal is the same value. 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:

What is the output of the following code segment?intc=6,d=12;if(cd)if(c8)Write(blue);elseWrite(Red);elseWrite(Green); Blue Red Green nothing

If the following code segment compiles correctly, what do you know about the variable x? if(x) WriteLine(OK); a. x is an integer variable. b. x is a Boolean variable. c. x is greater than 0. d. none of these

What is the output of the following code segment?inte=5,f=10;if(eff0) Write(Red); else Write(Orange);Â a. Red b. Orange c. RedOrange d. nothing

The program in the Programming Example: Fibonacci Number does not check whether the first number entered by the user is less than or equal to the second number and whether both the numbers are non-negative. Also, the program does not check whether the user entered a valid value for the position of the desired number in the Fibonacci sequence. Rewrite that program so that it checks for these things.

4. 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; }

(Modify) a. Modify the program you wrote for Exercise 7 to provide the mass of a person as an output, given his or her weight as an input to the program. Use your program to determine the mass of a person who weighs 140 lbf on Earth. b. Modify the program written for Exercise 7a to also output the person’s weight on Mars and the moon. The pull of gravity on Mars is 12.54ft/sec2=3.728m/s2,andonthemoonis5.33ft/sec2=1.625m/s2.

Write a program named GuessingGame that generates a random number between 1 and 10. (In other words, in the example above, min is 1 and max is 11.) Ask a user to guess the random number, then display the random number and a message indicating whether the users guess was too high, too low, or correct.
