Write nested for loops to produce the following output: It is V shape pattern.                         1              1                                               2          2                                                    3      3                                                      4  4                                                           5   (There should be 4 spaces between the 1’s, 3 spaces between the 2’s, 2 spaces between the 3’s, and 1 space between the 4’s)

Write C+ + statement(s) to do the following: (1, 2) Declare an array alpha of 50 components of type int. Initialize each component of alpha to -1. Output the value of the first component of the array alpha. Set the value of the 25th component of the array alpha to 62. Set the value of the 10th component of alpha to three times the value of the 50th component of alpha plus 10. Use a for loop to output the value of a component of alpha if its index is a multiple of 2 or 3. Output the value of the last component of alpha. Output the value of the alpha so that 15 components per line are printed. i. Use a for loop to increment every other element (the even indexed elements). j. Create a new array, diffAlpha, whose elements are the differences between consecutive elements in alpha. What is the size of dif fAlpha?

(Civil eng.) Write a C++ program to calculate and display the maximum bending moment, M, of a beam that’s supported on both ends (see Figure 3.8). The formula is M=XW(LX)/L, where X is the distance from the end of the beam that a weight, W, is placed, and L is the beam’s length. You program should produce this display: The maximum bending moment is xxxx.xxxx The xxxx.xxxx denotes placing the calculated value in a field wide enough for four places to the right and left of the decimal point. For your program, assign the values1.2,1.3,and11.2toX,W,andL.

(Civil eng.) Write an assignment statement to determine the maximum bending moment, M, of a beam, given this formula: M=XW(LX)L X is the distance from the end of the beam that a weight, W, is placed. L is the length of the beam.

(Simulation) Write a program to simulate the roll of two dice. If the total of the two dice is 7 or 11, you win; otherwise, you lose. Embellish this program as much as you like, with betting, different odds, different combinations for win or lose, stopping play when you have no money left or reach the house limit, displaying the dice, and so forth. (Hint: Calculate the dots showing on each die with the expression dots=(int)(6.0randomnumber+1), where the random number is between 0 and 1.)

(Mathematical functions) Write a program that calculates and displays values for y when y=xz/(xz) Your program should calculate y for values of x ranging between 1 and 5 and values of z ranging between 2 and 6. The x variable should control the outer loop and be incremented in steps of 1, and z should be incremented in steps of 1. Your program should also display the message Function Undefined when the x and z values are equal.

(Practice) a. Write output statements using cout that can be used to display values from the first, third, and seventh elements of each array declared in Exercise 2. b. Write a for loop that can be used to display values for the complete array declared in Exercise 2.

(Misc. application) a. Write a program that continuously requests a grade to be entered. If the grade is less than 0 or greater than 100, your program should print an appropriate message informing the user that an invalid grade has been entered; else, the grade should be added to a total. When a grade of 999 is entered, the program should exit the repetition loop and compute and display the average of the valid grades entered. b. Run the program written in Exercise 2a and verify the program by using appropriate test data.

(Electrical eng.) a. An electrical manufacturer tests five generators by measuring their output voltages at three different times. Write a C++ program that uses a nested loop to enter each generator’s test results, and then computes and displays the average voltage for each generator. Assume the following generator test results: 1stgenerator:122.5122.7123.02ndgenerator:120.2127.0125.13rdgenerator:121.7124.9126.04thgenerator:122.9123.8126.75thgenerator:121.5124.7122.6 b. Modify the program written for Exercise 3a to calculate and display the average voltage for all the generators. (Hint: Use a second variable to store the total of all the generator’s voltages.)

The body of a while loop can consist of ____________. a. a single statement b. a block of statements within curly braces c. either a or b d. neither a nor b
