Answer to Question #188878 in C++ for Asad

Question

Input a string from user in the following format:  Name_RollNo_GPA.

Now perform string tokenization operation on this string to separate the Roll no and GPA. Now based on those values perform the following operations:

If the Roll no is greater than 120 or less than 1 then print: Record does not exist.

Otherwise:

If the GPA is greater than or equal to 3.75 then print Faculty Honors

If GPA is less than 3.75 and greater than 3.5 then print: Excellent.

If GPA is less than 3.5 and greater than 3 then print: Good.

If GPA is greater than 2.7 and less than 3 then print: Satisfactory.

If GPA is less than 2.7 then print: You should work hard.

 

Note: You can call built in function
