3.Which of the following will read a string from a file with FILE* fpto char myString[81] properly (safely): fscanf(fp, "%s", myString ); fgets(myString, fp); fgets(fp, 81, myString); correct : fgets(myString, 81,fp) fscanf(fp,"%80s", myString); 4. If you issue the statement fpIn = fopen("myfile.dat", "a");and dat does not exist, the computer will: return NULLto fpIn as the file does not exist create the file in write mode, and position the file pointer at the beginning of the file create the file in write mode, close the file and return a warning open a file that most closely resembles the name 'myfile.dat'

Create a program that asks the user for the name of a file and then rearranges the contents of the file so that its lines are in alphabetical order. Use the STL algorithm sort.
Create a program that asks the user for the name of a file and then rearranges the contents of the file so that its lines are in alphabetical order. The program should modify the file, not just print its contents to the screen. Use the STL algorithm sort. C++
B7 Write a program that reads a file and find out the total uppercase, lowercase, whitespaces and digits occurred in the file.
A file contains only spaces, commas, colons, digits, and newlines in the following frequencies: colon (100), space (605), newline (100), comma (705), 0 (431), 1 (242), 2 (176), 3 (59), 4 (185), 5 (250), 6 (174), 7 (199), 8 (205), 9 (217). Construct Huffman code.
Write a program which reads the first two characters from the file “chars.txt” and writes thesum of their ASCII code values as a number into “codesum.txt”. Use an editor to create theinput file “chars.txt”. Your program is responsible to create the output file “codesum.txt”.You can safely assume that the content of the input file will be valid.(Please write in C programming language).
C++ Add a search command that asks the user for a string and finds the first line that contains that string. 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.

This is the statement it gives - Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20. Assume also the last names and first names do not contain whitespaces. The program performs the following tasks: Read the file name of the tsv file from the user. Open the tsv file and read the student information. Compute the average exam score of each student. Assign a letter grade to each student based on the average exam score in the following scale: A: 90 =< x B: 80 =< x < 90 C: 70 =< x < 80 D: 60 =< x < 70 F: x < 60 Compute the average of each exam. Output the last names, first names, exam scores,…
Assume that a file containing a series of names (as strings) is named names.txt and exists on the computer’s disk. Write a program that displays the number of names that are stored in the file. (Hint: Open the file and read every string stored in it. Use a variable to keep a count of the number of items that are read from the file.
