utilize the follow function headers:
Main()
WriteScores()
ReadScores()
First, the main function will ask the user, “do you want to record scores or read scores?” Depending on what the user inputs, the answer will determine whether to call WriteScores OR ReadScores. The WriteScores function will then ask the user, “how many scores do you want to add?”. The function will then read each of the players name and score as keyboard input, then save these as records in a file named scores.txt.
Sample output:
Do you want to read scores or write scores?
Type r or w: r

Practice problem we were given in C++ to review for test. Thanks
Write a program that reads data from a data file, the value of which is provided at the end of the problem. Your program is to incorporate the following requirements:
Data to the program is input from a file of an unspecified length; that is, the program does not know in advance how many numbers are in the file.
Save the output of the program in a file.
Write a function called getNumber which reads a number from the input file, outputs the number to the output file and the monitor and sends the input number to the function main. Make sure, both input and out file are being opened in the main program.
Write a function called classifyNumber which counts number of even, odd, and zero (occurrences of zero) available in the input file.
Have the program find the sum and average of the numbers and print only 10 numbers per line.
Write a function called printResult so that it outputs (in output file and monitor) even number of…
I need help in creating a C function that will read a specific line from a text file in C based on the randomly generated number ranging from 1 to 50. The function would have the parameter of the text file and would return the string that the specific line of the text file contains. Note(the text file only contains characters , sentences and no numbers)
Restrictions : Cant use break, exit(), break , continue,global variables. Only allowed to use stdio.h and string.h
For instance if the random number is 4 then the function would return the 4th line of the particular text file.

NOT C++, C#, etc. To create a program that MUST utilize the functions (argc, argv, char strstr, and possibly even Getline) to, 1. Open a file 2. Read the file 3. Read txt file line by line 4. count up the number of times a specified word is read(HOWEVER! IT CANNOT COUNT MORE THAN ONE WORD PER LINE!) ex. if the code comes across a line in a text file that has the word cookie in it 3 times. It can only count the word ONCE since it is counting line by line. Not all the words added up. 5. then display to the user the total number of lines with the specific word. ex. gcc -o <program name> ./<program name> <file name.txt> <"word to be searched"> then execute a total number of times words came up. Again, only count up by one even if there is that specified word multiple times in one line.arrow_forward

Hints: fgets() or scanf(), strncmp(), strlen(). For scanf(), you would have to use format specifiers to specify the width of the string for the output. 2) Your modified program should display an output “wrong password” for each of the following four cases: Case 1: input password = "by". (User input is half that of given password text) Case 2: input password = "bytebyte". (User input is twice that of given password text) Case 3: input password = "1234". (User input is a garbage text of same length) Case 4: input password = "12345678901234567890".

- Hello good afternoon, Write a C++ program that reads data from an input file, takes the data and computes student grades for an assignment by converting the raw score to a percentage given each student's score and the total points. The final score must be rounded up to the nearest whole value using the ceil function in the header file and displayed as a percentage. You must also display the floating-point result up to 5 decimal places. You must use at least 2 functions: one to print the last name of the student and another function to compute and print the percentage as well as "Excellent" if the grade is greater than 90, "Well Done" if the grade is greater than 80, "Good" if the grade is greater than 70, "Need Improvement" if the grade is greater than or equal to 60, and "Fail" if the grade is less than 50. The main function is responsible for reading the input file and passing the appropriate arguments to your functions.arrow_forward2. Write a complete C program that inputs marks of a student in 5 courses using any loop and writes these marks into an output file named myElements.txt. After that, it reads scores from myElements.txt and computes the grades based on the table below using a programmer-defined function char computeGrade(double score), and displays the grades on screen. - please, write the c program code and include comments on your code, contents of the file myElements.txt , and sample output.
