Write a C Program that takes an input (2 text.txt) files, and counts the number of times the elements of File 1, appear in File 2, and print the result as shown. Please read the example below:
Example:
File A:
BarcelonaDublinLas VegasLisbonLondonMadridNew YorkRioSan FransiscoShanghaiToronto
File B:
BarcalonaMadridMadridMadridMadridSan FransiscoTorontoVancouver

Write a function-based C++ program that reads a c-string from a file (input.txt) and an integer key from the console. Your program should encrypt the string by adding the key value to all its alphabets. Make sure that if adding the key value makes the alphabet go past the letter ‘Z’ or ‘z’, you must rollover and start over from ‘A’ or ‘a’ respectively. All other non-alphabetic characters should remain the same. Write the encrypted string into an output file (output.txt).
Example 1:
Input File
Aliens on Earth! Enter a key: 1
Output File
Bmjfot po Fbsui!
Example 2:
Input File
Welcome to Xiwan restaurant XYZ. Enter a key: 5
Output File

The prefix appears to the left of the @ symbol. The domain appears to the right of the @ symbol. For example, eng221t@mail.com, "eng2217" is the email prefix, and "mail.com" is the email domain Write a C++ program, which reads the email addresses from the file (input.txt) and find out whether it is a valid email address or not based on the following rules. 1. The email address must start with a letter (a-z or A-Z) (no numbers or symbols). 2. There must be an @ somewhere in the string that is located before the dot. 3. There must be text after the @ symbol but before the dot. 4. There must be a dot and text after the dot e.g.( ali@gmail.com). For each valid email address, the program should find its Prefix and Domain.

Exercise from Problem Solving…arrow_forwardCreate a complete C++ program that will read from a file, "studentInfo.txt", the user ID for a student (a number, but use a string to hold it). Next it will need to read three integer values that will represent the 3 exam scores the student got for the semester. Once the values are read and stored in descriptive variables it will then need to calculate a weighted course average for that student. Below is an example of what the calculation would be for the program. score1 * .3 + score2 * .3 + score3 * .4 The program will then determine the letter grade for that student and write the user ID and the letter grade to a file "studentGrade.txt" The standard grading scale will be used: A --> 90 – 100B --> 80 - 89.99C --> 70 - 79.99D --> 60 - 69.99F --> below 60 To keep from the user being confused as if anything happened or not, give them a ending statement i.e. Something like the following: Program has completed and the output can be found in 'studentGrade.txt' Files…arrow_forward
