- The python function file_first_chars takes one parameter, fname, the name of a text file, and returns a string made up of the first character from each line in the file. You may assume there are no blank lines in the file. Hint: Use a for loop to iterate over the lines of the file and accumulate the string of first characters.Find the error: #include<stdio.h> #include<stdlib.h> int main() { unsigned char; FILE *fp; fp=fopen("trial", "r"); if(!fp) { printf("Unable to open file"); exit(1); } fclose(fp); return 0; }The function print_last_line in python takes one parameter, fname, the name of a text file. The function should open the file for reading, read the lines of the file until it reaches the end, print out the last line in the file, report the number of lines contained in the file, and close the file. Hint: Use a for loop to iterate over the lines and accumulate the count. For example: Test Result print_last_line("wordlist1.txt") maudlin The file has 5 lines.
- This is for r Regarding a for loop, which of the following is not true? The for keyword must be followed by parentheses. Following the for statement, the code to be executed is recognized by it being indented. The number of times the loop will be performed is determined by the length of the vector passed to the for keyword. The for loop can contain other for loops.In C++ Stuck and could use help with coding a loop to find the array location of each source node inside the file input loop in main(). Use get_value() to compare a node’s value to source_name and If the node does not exist, add it to the array using the set_value() function and incrementing n. Save index. Comment out the output lines in the file input loop in main().

The C code is given (see Table3) Table3 if ((fp = fopen(filename, r )) == NULL) { printf("Error. Cannot read from file %s. Exit\n", filename); exit( 1 ); } while (fgets(line, sizeof line, fp) != NULL) { printf("Successfully copied"); } fclose(fp); Based on the above program, answer the following: a) Write down how many systems call this program invokes? b) Explain what type of system call it is.

- Consider the following code segment: done = False while not done : try : filename = input("Enter the file name: ") inFile = open (filename, "r") except IOError : print ("Error: File not found.") It is supposed to keep on prompting the user for file names until the user provides the name of a file that can be opened successfully. What line of code should be placed in the blank to achieve this goal? Select one: done = inFile done = True done = not inFile done = FalseThe 2 pictures are the beginning of the lab. The below is for part 2. read_file(0, clear_file); // Read in a file with of unknown length, getting the length from the file read. clear_file is a string containing the path to the clear text file. This function returns a char array created with memory allocation. read_file(len, clear_file); // Where len > zero, reads len chars from a file. clear_file is a string containing the path to the clear text file. This function returns a char array created with memory allocation. write_file(0, key, key_file); // Writes a string to file until the \0 char is reached. key is the string of random chars and key_file is a string containing the path of the text file. write_file(len, cipher, cipher_file); // Where len > zero, writes len chars to a file. cipher is the cipher string of chars and cipher_file is a string containing the path of the text file. The menu in main() should look like: Encrypt a file: 1Decrypt a file: 2Exit:…Task 2: Reading lines from a FileWrite C code which will read a line of characters (terminated by a \n) from input_file into a character array called buffer. NULL terminate the buffer upon reading a \n.NOTE:Your source code must display any of the given sample output below.It means your source code should be flexible enough to meet any of the given sample output.Your source code output must be identical to any of the given sample output.It means you have to strictly follow what are the displayed text, labels, casing of characters in the sample output.Strictly follow the naming of file.
