matching one string to another

[Andym]

I know that I can use istringstream to match the text from one text file to another but I just cant wrap my head around how that would look in code. I need help with this because my project is due tomorrow night and I need to spen the day with my mom. its her 85th birthday and its her first birthday since my dad passed. can someone please help me?

66 post and you haven't mastered code tags ?

your missing
using namespace std;

I'm having trouble wrapping my head around your code. Maybe you should start smaller and get it working a little at a time.

Do you have to use istringstream, or is that just something you would use if it would work ?

[Andym]

Well for some reason it would not allow me to "format" my code.
I am just looking for the easiest way to match strings.

[SamuelAdams]

Tell me quickly what your trying to match.

I saw your comment

//======================================================
			///======this is where I think the math search should go
			//====================================================== 

but i'm not clear on what your searching.
Last name & first
or
StudentId
or maybe both

I am just looking for the easiest way to match strings.

if(str1 == str2) {
it's a match!
} 

[Andym]

I need to search for a match of course numbers and then get the credit hours of one and calculate the GPA based on other info. I'm gonna try the == operator.
