C++ Error...IDK what is wrong!
I am a beginner at C++...
I made this but I don't knowwhat it means
when the error says " error C2106: '=' : left operand must be l-value "
can someone help me???
~this is the code~
// assignment operator
#include <iostream>
using namespace std;
int main ()
{
int a,b,c,d,e;
2 = a;
a = b;
b = c;
c = d;
d = e;
cout << "If A=2, E=D, D=C, C=B, and B=A then ";
cout << "E=";
cout << e;
return 0;
}
Re: C++ Error...IDK what is wrong!
this
should be:
also this:
Code:
cout << "If A=2, E=D, D=C, C=B, and B=A then ";
cout << "E=";
cout << e;
could be:
Code:
cout << "If A=2, E=D, D=C, C=B, and B=A then E=" << e << endl;
Re: C++ Error...IDK what is wrong!
it still says
1>.\demo.cpp(9) : error C2106: '=' : left operand must be l-value

OK, so do you want to click the save button or should I?:rolleyes:
rebuild all too. In other words.... save this short program, compile it, link it and run it.
Sometimes CG is like an old Scrubs episode.
Re: C++ Error...IDK what is wrong!
the first error went away but now it says my variables are unitialized and that e = 0 when it e should =2

Boy, more than half those vars aren't even initialized. ... I'm surprised the computer hasn't blown up :lol:

hahaha, you posted just before I posted.
Yep, you have to intilize the vars.
try something like:
b=2;
c=3;
d=4;
e=5;
.... then see what happens. :thumb:
Re: C++ Error...IDK what is wrong!
I have a cool Idea, go and get a good book!

And don't get mad, you have to learn how to initialize
your variables.
int a = 0; //Now we just declared and initialized your varable all in one step
I'm sorry but my carpal tunnel keeps me from typing too much more.
Re: C++ Error...IDK what is wrong!
i understand now... you cant set a variable like 'a' to equal 'b' and 'b' to equal 'c'...i wanted to make a chain ~ where they all equaled 2...but i guess u can't

Hey don't let it get to you, we all had to start somewhere. When I first started with "C" I was so happy to print something on the screen, put the exe on a diskette, load the program on a different computer and show my friends.
Once you get the program to print what you want then you can get rocking.
Don't give up so fast. :D, I'll see if I can find a good C++ tutorial where you can copy and paste code and make it work.
Just remember with C/C++/VC++/MFC, getting off the ground is the hardest part. People are here to help, you might have to develop a hard shell, but it's worth it.
Keep plugging at it. :D:thumb:
