Hi, I have to write a C++ program using txt file, and I really need some help.

score.txt is givien, with each line containing 3 test scores of each students.
Bob 66 55 60.5
Robby 46 32 98
Anne 83 45.5 50

Student names should be stored in an array of strings, and their marks should be in a 2D array.

I can select two options, 1 or 2, and each option should perform different tasks.

 

Option 1:

I should write a program to sort the records in ascending order of the column number I input, and output the results as a table. 0 is student name, 1, 2, 3, 4 each represent test 1, 2, 3, and 4.

 

For example, if I type 0, it should print a table like this:

Anne      83      45.5    50

Bob        66      55       60.5

Robby    46     32        98

if I type 2, then it should be like:

Robby    46     32        98

Anne      83      45.5    50

Bob        66      55       60.5

 

Option 2:

I should be able to update the score, and write the updated score table sorted by student name to file new.txt.

I should input student name, test number, and change the score.

 

For example, if I type like this:

Name: Anne

Test: 3

New mark: 100

 

then new.txt should be:

Anne      83      45.5    100

Bob        66      55       60.5

Robby    46     32        98

I just started to learn C++, so I really need help.

Thanks.
