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;

To keep the plot moving, that's why.

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.

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

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.

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
