- how to output the contents of a file to the screen? also how to count the following items using c++ codearrow_forwardInstructions Consider the following incomplete C++ program: #include <iostream> int main(){ ...} Write statements that include the header files fstream, string, and iomanip in this program. Write statements that declare inFile to be an ifstream variable and outFile to be an ofstream variable. The program will read data from the file inData.txt and write output to the file outData.txt. Write statements to: Open both of these files Associate inFile with inData.txt Associate outFile with outData.txt Suppose that the file inData.txt, data set 1, contains the following data: Giselle Robinson Accounting 5600 5 30 450 9 75 1.5 The first line contains a person’s first name, last name, and the department the person works in. In the second line, the first number represents the monthly gross salary, the bonus (as a percent), and the taxes (as a percent). The third line contains the distance traveled and the traveling time. The fourth line contains the number of coffee cups sold…arrow_forwardPlease help with C++, CANNOT use array or vector CAN ONLY USE BELOW #include<iostream> #include<fstream> #include<string> #include<iomanip> This program numbers the lines found in a text file. (text file name is story.txt) Write a program that reads text from a file and outputs each line to the screen and to another file preceded (preceding file name outputfile.txt) by a line number. Print the line number at the start of the line and right-adjusted in a field of three spaces. Follow the line number with a colon, then one space, then the text of the line. You should get a character at a time and write code to ignore leading blanks on each line. You may assume that the lines are short enough to fit within a line on the screen. Otherwise, allow default printer or screen output behavior if the line is too long (that is, wrap or truncate). A somewhat harder version determines the number of spaces needed in the field for the line numbers by counting lines before…arrow_forward
