Solved in 2 steps
- 1. Consider the following incomplete C++ program: #include int main() { … } a. Write a statement that includes the header files fstream, string, and iomanip in this program. b. Write statements that declare inFile to be an ifstream variable and outFile to be an ofstream variable. c. 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, and associate outFile with outData.txt. d. Suppose that the file inData.txt 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 and the cost of each coffee cup. Write statements so that after the program executes, the contents of the file outData.txt are as shown below. If necessary, declare additional variables. Your statements should be general enough so that if the content of the input file changes and the program is run again (without editing and recompiling), it outputs the appropriate results. Name: Giselle Robinson, Department: Accounting Monthly Gross Salary: $5600.00, Monthly Bonus: 5.00, Taxes: 30.000 Paycheck: $4116.00 Distance Traveled 450.00 miles, Traveling Time: 9.00 hours Average Speed: 50.00 miles per hour Number of coffee Cups Sold: 75, Cost: $1.50 per cup Sales Amount = $112.50 e. Write statements that close the input and output files. f. Write a C++ program that tests the statements in parts a through e.Write a C program that, given a text file, constructs Huffman code based on the character frequencies of the file and then encodes the file accordingly. The executable must accept the following command line options:• -i filename for the input file • -o filename for the output fileWrite a C program named toupper.c that reads the contents of a file, and writes to another file after changing all lowercase letters in the input file to uppercase. The name of the input file and the output file are to be passed as command line arguments. Assume there are only ASCII characters in the input file. The length of the input file is not known beforehand. So make sure your program keeps reading bytes until EOF is reached. Use the library function toupper to concert letters into uppercase. Example: The program is run from the command line as follows; C:\>toupper.exe infile.txt outfile.txt Suppose the contents of the input file infile.txt is: AbcdefG The contents of the output file outfile.txt should be: ABCDEFG
- Write a C++ program that counts the number of non white-space characters in an input text file. Program takes as command argument(s) the name of the input file (and the output file with option -f). Based on the option flags, it displays the output on the standard output, or writes the output to an output file. The command format is as follows:command -f inputfile outputfile or, command -s inputfile -f indicates writing to an output file;-s indicates displaying the output on the screen. Also notice the errors caused by incomplete arguments. Including: (1) The name of the author of the program (your name) and the date it was written, (2) a concise description of what the program does, (3) a clear description of its limitations if it does not meet all specifications, and (4) explanation for critical code and data declarations. The same should also be done for each function written in the program.Write a C program, called reverse, using standard I/O functions, to take a file as inputthen copies it to another file in reverse order. That is, the last byte becomes the first,the byte just before the last one becomes the second, etc.The program call should look like:reverse fileIn fileOutWrite a C++ program that asks the user for a file name and a word for which to search. The program should search the file for every occurrence of the word. When the word is found, the line it contains should be displayed. After all of the occurrences have been found, the program should display the number of times the word was found in the file.
- Write a C program to print the given X number pattern series .• Your program should ask for a single input – the number, which will be a digit from 1-9 (if the number is not within the range, the program will terminate) o e.g., if the user enters 10, or -1, the program will terminate • Then output the number and in the line below, the corresponding X pattern onto a file. The output filename is ‘CP3out.txt’. Please leave 2 lines in between successive outputs for clarity. Note: • The appearance of the X: your output must match the examples below. • Also note that your code must not hard code the output corresponding to each individual number (1-9) but rather, be generalWrite a C program which will write user’s name and age to a sequential access filecalled ‘sequential_file.txt’. Each time the program is executed, the data already in thefile must not be overwritten. Ensure that each time text is written to the file, it is place on a new line inaddition the program should be able to read, display and count the data stored in the sequential access file called 'sequential_file.txt'. read, display and count the data stored in a sequential access file called ‘sequential_file.txt’.Write a C++ program to create a file “STORY.txt” which contains following lines:“The rose is red.A girl is playing there.There is a playground.An aeroplane is in the sky.Numbers are not allowed in the password.”Then write a function in C++ to count and display the number of lines not starting with alphabet 'A'present in a text file.
- You must solve the problem in C++. (Process scores in a text file) Suppose that a text file Exercise13_3.txt contains an unspecified number of scores. Write a program that reads the scores from the file and displays their total and average. Scores are separated by blanks.Write C++ Program that does the following: •Instead of reading data from the user, create a txt file that will be imported into the code •The format of the file is: –First line: number of records –Subsequent lines: Last name on a line by itself First name and three homework grades •Read function: parameters are –An instream, passed by reference, from which to read the data –Fields for firstname, lastname, grade1, grade2, grade 3 •The read function should read in the data from the instream. It is a void function •What types are the parameters? How will you pass them? •Write function: parameters are –Firstname, lastname, grade1, grade2, grade3, average grade, letter grade –What types are those parameters? Do you need to pass them by reference? •The write function will write the data to the screen formatted neatly –Which formatting instructions will you need to use? Overall program flow: •Open the file in the main program. •Read in the number of records •For each record,…Write a C program which performs the following tasks:a. Create a Number.txt fileb. Write a program that prints x, x2(square) and x3(cube) in a file for x=1 to 10c. Close the file.d. Read Number.txt file and if any number is greater than 40 and odd, it should be ignored.e. Display the file contents on console
