C++ :: Output Information For Three Students - Calculating Averages

Write a C++ program to output information for three students. The information stored in your program contains student’s first name, middle name, last name, and test score. The following shows the information for the three students, where test score is in the int type.

John Jacob Smith 78
Mary Jane Weems 82
Dave Joe Dale 61

Your program should declare three named string constants for the three students. Each constant contains the student’s first name, middle name, and last name. You may use three int variables to hold values for the three test scores. The first name, middle name, and last name of a student are then extracted using the substr() function shown in class. Your program should also compute the average (in floating-point number format) for the three test scores. The average score computed should be printed to the screen with 2 digits displayed after the decimal point.

The following shows the output from the program. Note that all the output is left-justified with 15 character positions reserved for each.
