- To be done using C programming:Two identical files are given with different names to them. But some characters in the content of the second file are corrupted. Find the line number and their position where those corrupted letter exists as well as Total number of corrupted (error) letters. Examples: Input: File1.txt contains It is fun to code with C File1.txt contains It is fun to code with C# Output: Line Number : 2 Error Position:2 Total Errors:1 Steps Open two file using File pointer in read only mode. Fetch data of file in two char variable one by one until end of file. If variable encounter new line then increment line number and reset position to zero. If variables are not equal then increment number of error and print error line as well as error index.Hello, I was wondering if an expert could help me out with a coding error. I am trying to write a code that reads from a text file but I keep getting an error. I will attach the code and error as seperate files for you to take a look at.Write a program, led_pb.c, compiled with GCC on the RPi 3b/3b+, that performs the following steps using the provided sysfs_gpio files:a. Include the sysfs_gpio.h fileb. Initializes the LED pin to be an output by calling gpioOutput()c. Initializes the switch pin to be an input by calling gpioInput()d. Turns on the LED using gpioWrite()e. Enters a while loop that calls gpioRead() and waits for the switch to read 1f. Turns off the LED using gpioWrite()

- Using a UNIX environment, write a program in C++ that will: Open a directory "/home/timapple/" and step through each individual directory. Determine file type and display it along with the name of the file. Just provide the relevant code segment in a POSIX compliant system.You lost me here: stdafx.h should I be creating a seperate file from here down? I don't know how to separate the coding from that down, I am confused.2. Write a program that opens a file in read-only mode and maps the entire file into the virtual-memory address space using mmap. The program should search through the bytes in the mapped region, testing whether any of them is equal to the character X. As soon as an X is found, the program should print a success message and exit. If the entire file is searched without finding an X, the program should report failure. Time your program on files of varying size, some of which have an X at the beginning, while others have an X only at the end or not at all. Please write the program in C
