C++ Error...IDK what is wrong!

[Frederick Lenz]

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;
}

[ahoodin]

this

2 = a;

should be:

a=2;

also this:

cout << "If A=2, E=D, D=C, C=B, and B=A then ";
cout << "E=";
cout << e;

could be:

cout << "If A=2, E=D, D=C, C=B, and B=A then E=" << e << endl;

[Frederick Lenz]

it still says

1>.\demo.cpp(9) : error C2106: '=' : left operand must be l-value

Post your code

[Frederick Lenz]

// assignment operator

#include <iostream>
using namespace std;

int main ()
{
int a,b,c,d,e;
a=2;
a = b;
b = c;
c = d;
d = e;

cout << "If A=2, E=D, D=C, C=B, and B=A then E=" << e << endl;

return 0;
}

OK, so do you want to click the save button or should I?

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.

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

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.

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.

[Frederick Lenz]

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

No, I can, but you can't cuz you haven't got that far yet. Get readin!

hahaha...ok
i dont KNOW
but i understand that they can't all equal themselves and stuff
but one day i will overcome you
and i will be all
*boom chicka boom chicka boom*
and you will be all
*boop oop eep doop!*
......yeah.....thats exactly how it will be........

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. , 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.
