(Total Sales) Use a two-dimensional array to solve the following problem. A company has four salespeople (1 to 4) who sell five different products (1 to 5). Once a day, each salesperson passes in a slip for each different type of product sold. Each slip contains:
- The salesperson number
- The product number
- The total dollar value of that product sold that day
Thus, each salesperson passes in between 0 and 5 sales slips per day. Assume that the information from all of the slips for last month is available. Write a

- (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(Numerical) Given a one-dimensional array of integer numbers, write and test a function that displays the array elements in reverse order.arrow_forwardi. Creates a matrix using: B=rand (20) a-write a program to find all numbers less than or equal 0.5 and put them in a new matrix with dimension 20x10. you can extend with zeros to fill the matrix. b- Do same as point a for all numbers above 0.5. c- Count all the numbers less or equal 0.3 , the numbers between 0.3 and 0.7 and count the numbers more than or equal 0.7.Put the results in a new vector with dimension 3x1. d- Replace the numbers of between 0.7 and 0.9 with 1. e- Add all the elements column wise.arrow_forward
- Determine whether the following array declarations are valid. If a declaration is valid, write VALID. If it is invalid, you can make assumptions and write a correct declaration.arrow_forwardLanguage: C Pascal’s triangle is a triangular array, useful for calculating the binomial coefficients, n k , that are used in expanding binomials raised to powers, combinatorics and probability theory. 0 0 1 0 1 1 2 0 2 1 2 2 3 0 3 1 3 2 3 3 4 0 4 1 4 2 4 3 4 4 Evaluating the values of the binomial coefficients, you get the following pattern, 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 The number of the entries in each row is increased by one, as we move down. Each number in the triangle, is constructed by adding the number above it and to the left, with the number above it and to the right. The blank entries as treated as 0. Using the recursion, implement the function that computes the Pascal’s triangle. Prarrow_forwardDecide which of the following statements is either true or false and re-correct the false ones. 5. do … while repetition statement gives full control on the code block to be repeated. 6. All binary operators except for the assignment operators are evaluated from Left to Right 7. A ragged 2D array is a 2D array in which each column may contain different number of rows. 8. Each row in a 2D array could be dealt with as 1D array. 9. The following statement creates and initializes the array x: int x[] = {10, 20, 30, 40, 50}; 10. A Java program may contain more than one method with the same signature.arrow_forward
