Describe in your own words how to pass a variable and a string to a procedure and also how to store that into an array.

(Electrical eng.) a. An engineer has constructed a two-dimensional array of real numbers with three rows and five columns. This array currently contains test voltages of an amplifier. Write a C++ program that interactively inputs 15 array values, and then determines the total number of voltages in these ranges: less than 60, greater than or equal to 60 and less than 70, greater than or equal to 70 and less than 80, greater than or equal to 80 and less than 90, and greater than or equal to 90. b. Entering 15 voltages each time the program written for Exercise 7a runs is cumbersome. What method could be used for initializing the array during the testing phase? c. How might the program you wrote for Exercise 7a be modified to include the case of no voltage being present? That is, what voltage could be used to indicate an invalid voltage, and how would your program have to be modified to exclude counting such a voltage?

A structure that allows repeated execution of a block of statements is a(n) _____________. sequence selection array loop

(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.

(Practice) Write a program to input eight integer numbers in an array named temp. As each number is input, add the numbers to a total. After all numbers are input, display the numbers and their average.

(Modify) Modify the program written for Exercise 9 by adding an eighth column to the array. The grade in the eighth column should be calculated by computing the average of the top three grades only.

(Practice) Write array declarations for the following: a. A list of 100 double-precision voltages b. A list of 50 double-precision temperatures c. A list of 30 characters, each representing a code d. A list of 100 integer years e. A list of 32 double-precision velocities f. A list of 1000 double-precision distances g. A list of 6 integer code numbers

(File creation) Write a C++ program that creates an array containing the integer numbers 60, 40, 80, 90, 120, 150, 130, 160, 170, and 200. Your program should then write the data in the array to a text file. (Alternatively, you can create the file with a text editor.)

(Electrical eng.) Write a program that declares three one-dimensional arrays named volts, current, and resistance. Each array should be declared in main() and be capable of holding 10 double-precision numbers. The numbers to store in current are 10.62, 14.89, 13.21, 16.55, 18.62, 9.47, 6.58, 18.32, 12.15, and 3.98. The numbers to store in resistance are 4, 8.5, 6, 7.35, 9, 15.3, 3, 5.4, 2.9, and 4.8. Your program should pass these three arrays to a function named calc_volts(), which should calculate elements in the volts array as the product of the corresponding elements in the current and resistance arrays (for example ,volts[1]=current[1]resistance[1]). After calc_volts() has passed values to the volts array, the values in the array should be displayed from inside main().

(Numerical) a. Define an array with a maximum of 20 integer values, and fill the array with numbers input from the keyboard or assigned by the program. Then write a function named split() that reads the array and places all zeros or positive numbers in an array named positive and all negative numbers in an array named negative. Finally, have your program call a function that displays the values in both the positive and negative arrays. b. Extend the program written for Exercise 6a to sort the positive and negative arrays into ascending order before they’re displayed.
