Question

I need simple program in C++ that will open text file and going line by line find second argument by knowing first in list.

Content of text file:

1, red
2, blue
3, green
4, orange

So I need a program that will go line by line and each line turn into array ( of two elements ) and then compare first element with user interactively inserted number.

So if user insert 2, it goes line by line, comparing first element of array-ed line and if it matches, it prints second element in array ( blue ), and if user type 3, it prints green…

I have always working in PHP, and it’s much easier than this, so I am stuck a little bit with this now… :/
