- Write a short program to modify the contents of a 1000 bytes file “/dir/file” (expressed in [0-999]) to “[0-459]abc[463-999]xyz[h]end” (NOTE: “[m-n]” means the file’s original contents from offset m to n; “[h]” means a 300-bytes file hole).Using Programming C++..... a) Write a program that reads a text file in which each line in the file consists of a first name, a last name, following by 4 grades (double types) like Tim Hanes 78.3 98.0 80.5 72.3 The program must read every line of the text file, find the average of the 4 grades then print the names followed by the averages (one name per line) in a second file as well as on the monitor. b) Create the text file with at least 5 entries with the format given in part (a). Give the absolute path of the file in your computer. Test your program in part 2(a) on this file.Write a program to sort a list of numbers of unknown length. Your program must• read in a list (of unknown size) of numbers (think about types) from an input file namedinput.txt,• use a function, written by you, to sort the list in ascending order and• write the sorted list to an output file named output.txt.
- (This is for DevC++. I use version 5.11) Edit the following code to read the input for 10 students from a file testData1.txt and output the average of scores for 10 students using a loop. #include <fstream>using namespace std;#include <iomanip>int main(){string name1,name2,name3;double score1,score2,score3;char c1,c2,c3;double avg;ifstream inputFile;ofstream outputFile;inputFile.open("testData1.txt");outputFile.open("Results.txt");inputFile.clear();inputFile>>name1>>score1>>c1;inputFile.clear();inputFile.ignore(200,'\n');inputFile>>name2>>score2>>c2;inputFile.clear();inputFile.ignore(200,'\n');inputFile>>name3>>score3>>c3;avg =(score1 + score2 +score3)/3.0;outputFile << endl<<setw(20)<<left<<"Name" <<setw(20)<<"Score"<<setw(20)<<left<<"School Year";outputFile << endl<<setw(20)<<left<<"----"…Write a program to count occurrences of a character in a file Character to be input from the keyboard. Result to be displayed on the monitor. Program only works if no more than 9 occurrences are found. Here is the data I used for the screen print attached .ORIG x4000 .FILL x57 ;W.FILL x69 ;i.FILL x6c ;l.FILL x6c ;l.FILL x69 ;i.FILL x61 ;a.FILL x6d ;m.FILL x20 ; space.FILL x54 ;T.FILL x2e ;..FILL x20 ; space.FILL x4d ;M.FILL x69 ;i.FILL x6e ;n.FILL x6b ;k.FILL x04 ;EOTTRAP x25.END3. Write a function which reads an already existing file “File1.txt” and write digits (0-9) in to a new text file “mynumber.txt” and non digits into a file “Text.txt”.in c++
- Write a Python program to combine each line from the first file with the corresponding line in the second file and then save it in a 3rd file. Consider, both the files have same number of lines. Assume, each line has a newline(\n) at the end. ========================================================= Example:Input from file 1:HelloHiNice Input from file 2:BadWorseWorst Output in 3rd FIle:Hello BadHi WorseNice Worst ========================================================= Hint(1):Use the write() function what will be the answer of this in python programming languageA record from a binary file named SDQCC.BIN has, in this order, 3 integers, a character and then two doubles. All integers are either positive or zero. The doubles are negative or positive. The file has 2000 records but we are only interested in the first 200 records. Write a block of code using the starter program below to find the (1) Largest among the third integers from all records and the (2) Average of all negative first doubles from the file. At the end print both values with the message from the starter program. ** Use the partial code below. You can create other variables, but not change the names of the ones below. Must use the file handler for credit. ** #include <iostream>#include <fstream>using namespace std;// ---------------------------------------int main(){ // No credit if declaring another File handler fstream Bf; int Largest; // Cannot change name double AVG; // Cannot change name // ---- code ------ // ----- Print: Cannot…1. Write a function num_double to read file (f1.txt), double all the numbers, keep the string (no change), and write to another file (f2.txt), for example: >>># f1.txt-“I have 5 books and 3 pens...” >>> f2 = num_double(f1) >>> # f2.txt – “I have 10 books and 6 pens ...”
- Suppose the disk file foobar.txt consists of the six ASCII characters foobar Then what is the output of the following program?1 #include "csapp.h"23 int main() 4 {5 int fd1, fd2;6 char c;78 fd1 = Open("foobar.txt", O_RDONLY, 0);9 fd2 = Open("foobar.txt", O_RDONLY, 0);10 Read(fd1, &c, 1);11 Read(fd2, &c, 1);12 printf("c = %c\n", c);13 exit(0);14 }Count how often each bit is set in all the bytes of the given binary file. Open the file with the given name as a binary file. Count how often each bit is set in all the bytes of the file. A byte value returned by infile.get outside the range from 0 to 255 indicates the end of the file. Once you have a byte, you can get the bits like this: for (int i = 0; i < 8; i++) { if (byte % 2 == 1) { // The i-th bit is set } byte = byte / 2; } CODE SHOWN BELOW: #include <iostream>#include <fstream>#include <string> using namespace std; int main(){int bit_counts[8];for (int i = 0; i < 8; i++) { bit_counts[i] = 0; }fstream infile;string filename;cin >> filename; /* Your code goes here */ int largest = 0;for (int i = 0; i < 8; i++){cout << i << ": " << bit_counts[i] << endl;}return 0;}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.
