- (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.arrow_forward(Numerical) Using the srand() and rand() C++ library functions, fill an array of 1000 floating-point numbers with random numbers that have been scaled to the range 1 to 100. Then determine and display the number of random numbers having values between 1 and 50 and the number having values greater than 50. What do you expect the output counts to be?arrow_forward(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?arrow_forward
- 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?arrow_forwardin c++ Given the following, use a range-based for loop to load the array with user input (include a prompt cout followed by cin):const int SIZE = 5;int numbers[SIZE];arrow_forwardFile names: color_square.py, chessboard.py, test_squares.py Positions on a chess board are identified by a letter and a number. The letter identifies the column; the number identifies the row. See the image below. You will provide the functions that allow us to determine: if a chessboard square is either black or white, given its coordinates. If the row/column is valid or not for the standard chessboard For example, if we pass in “d” for the column and 4 for the row, your function that determines color should return the string: “BLACK”. If we pass in "k" for the column to your function that validates columns, that function should return the boolean False. Requirements: Your function for validating the column should be able to accept upper or lowercase strings as parameters. Your functions for validating the row should be able to accept integers or strings as parameters. Your function that determines black-or-white may assume that the input has been validated prior to us calling…arrow_forward
- Machine Problem. Using arrays, write a C ++ program that will let user input the array size (how many elements). After inputting the array size, it should ask the user for the elements of the array. After inputting the elements of the array, it will prompt the user to choose the following options: 1. Get the sum of all the array elements. 2. Sort the numbers from largest to smallest. 3. Sort the numbers from smallest to largest. 4. Get the average of the array elements. The output must be similar to the sample below. Use cin, cout, and iostream only. Thank you!arrow_forwardWrite C++ statement(s) to do the following: 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 twenty-fifth component of the array alpha to 62. Set the value of the tenth component of alpha to three times the value of the fiftieth 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. Use a for loop to increment every other element (the even indexed elements). Use a for loop to create a new array, diffAlpha, whose elements are the differences between consecutive elements in alpha.arrow_forwardNEED CODING IN PYTHON OR JAVASCRIPT BUT NOT C++ consider an input string TAM of letters ‘A’, ‘M’, and ‘T’. This string, which is given by the user, ends with ‘#’. It should be stored in a table (or array), called TAMUK. The number of each of these letters is unknown. We have a function, called SWAP(TAM,i,j), which places the ith letter in the jth entry of string TAM and the jth letter in the ith entry of TAM. Note that SWAP(TAM,i,j) is defined for all integers i and j between 0 and length(TAM)–1, where length(TAM) is the number of letters of TAM. 1. Using our algorithmic language, write an algorithm, called Sort_TAM, which sorts the letters in the array TAMUK in a way that all T’s appear first, followed by all A’s, and followed by all M’s. The algorithm Sort_TAM should have one parameter: The array TAMUK. Also, your solution is correct only if the following four constraints are satisfied: - Constraint 1: Each letter (‘A’, ‘M’, or ‘T’) is evaluated only once. - Constraint 2: The…arrow_forward
