- please code in pythonredact_file: This function takes a string filename. It writes a new file that has the same contentsas the argument, except that all of the phone numbers are redacted. Assume that the filename has onlyone period in it. The new filename is the same as the original with '_redacted' added before theperiod. For instance, if the input filename were 'myfile.txt', the output filename would be'myfile_redacted.txt'. Make sure you close your output file.The first hard task in this function is to make the output filename from the input filename that waspassed in. You can break it into two pieces by splitting on the dot or by using the index method andslicing. Then put it back together again using string concatenation.We are also working with files in this one. To open a file with a filename stored in the variable fname,in read mode use the open function as such: fp = open(fname). You will need to open the outputfile in write mode: open(fname, 'w'). Then you can traverse the…File redirection allows you to redirect standard input (keyboard) and instead read from a file specified at the command prompt.

The search starts at the first line currently displayed and stops at the end of the file. If the string is found, the line that contains it is displayed at the top. In case the user enters a string X that does not occur in the file, the program should print the error message: ERROR: string "X" was not found. Attached is the first lines of the .txt file

This DNA test measures the various parts of the sequence and assigns them a letter. While the letters could be anything from A to Z, the only letters that matter for this test are the letters {A,B,C,D} all other letters can be ignored completely.

- Body Mass Index Write a program that reads names, weights, and heights from bmi.dat (provided with starter code; do not change the file name). Use the information to calculate and displays a person’s body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula: BMI = weight × 703 / height2 where weight is measured in pounds and height is measured in inches. The file is in the format name weightInKG heightInCM You will read the name, weight and height for 4 people from the file, and you will need to convert the weights in the file to pounds (note that 1 kilogram = 2.2 pounds) and the heights to inches (2.54 cm = 1 inch). The program should display the person's name along with the calculated BMI and a message indicating whether the person has optimal weight, is underweight, or is overweight. Your output should look like A person’s weight…BinaryFileRead.cpp // BinaryFileRead.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include <iostream> using namespace std; int main() { int *arrayToSort; char fileName[50]; int size,readVal; cout << "Enter a filename to sort => "; cin >> fileName; FILE *inFile; fopen_s(&inFile,fileName, "rb"); fread(&size, sizeof(size), 1, inFile); arrayToSort = new int[size]; for (int i = 0; i < size; i++) { fread(&readVal, sizeof(readVal), 1, inFile); arrayToSort[i] = readVal; } fclose(inFile); return 0; } Timing.cpp // Timing.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include <iostream> #include <time.h> //ctime #include <sys/timeb.h> //_timeb _ftime_s using namespace std; int main() { struct _timeb timebuffer; char timeline[26]; _ftime_s(&timebuffer); ctime_s(timeline,sizeof(timeline), &(timebuffer.time)); printf("The time is %.19s.%hu %s", timeline,…getline(myfile,str); * 2 points writes a line of text str from the file myfile reads a line of text to str from the file myfile writes a character str to the file myfile reads a character str from the file myfile
