A valid email address consists of an email prefix and an email domain, both in acceptable formats. The prefix appears to the left of the @ symbol. The domain appears to the right of the @symbol. For example, eng221k@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. You must have to use only one user defined function that has the following prototype. bool checkValid(string email); In this function definition you have to check whether the email address is valid or not and for the valid email address find its prefix and domain. The program should write the output to the file (output.txt). Sample input and output files are given below.

Question

A valid email address consists of an email prefix and an email domain, both in acceptable formats. 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.
You must have to use only one user defined function that has the following prototype.
bool checkValid(string email);
In this function definition you have to check whether the email address is valid or not and for the valid email address find its prefix and domain.
The program should write the output to the file (output.txt). Sample input and output files are given below.
Output.txt
ahmed@squ.edu.om : valid
Prefix : ahmed
salim234@gmail.com : valid
Prefix : salim234

49. Write a C program that will find the sum of all prime numbers in a given range. The range will be specified as command line parameters. The first command line parameter, N1 which is a positive integer, will contain the lower bound of the range. The second command line parameter N2, which is also a positive integer will contain the upper bound of the range. The program should consider all the prime numbers within the range, excluding the upper bound and lower bound. Print the output in integer format to stdout. Other than the integer number, no other extra information should be printed to stdout. Example Given inputs “7” and “24” here N1= 7 and N2=24, expected output as 83.
Help write a C++ Program to do the following: This is to create a prototype for a Web browser. You’ll do this by transforming the file viewer created (SHOWN BELOW) into a browser for a web of files that are all located on a single computer. (This is in contrast to the real World Wide Web whose pages are located all over the world.) Details The files in this web of files are plain text files that may contain anchors that provide links to other files. More precisely, an anchor is a string of the form 1 where filename is the name of another file and text is a piece of text. For example, here’s a line of text that contains an anchor: More is available. To keep things simple, assume that every anchor is separated from adjacent text by white space and that the strings filename and text cannot contain white space. Your browser should work exactly like the file viewer, except for the following: 1. When an anchor is displayed, it should appear as [n] where n is a number that is unique to…
Create 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…
