error: ISO C++ forbids assignment of arrays

The problem is when I'm trying to compare two strings. a1 and " ". The string a1 is set to [3].

If the comparison is true then it makes a1 = ".."

Here is the source code. I made most of it when I only read half of my C book, so PLEASE, bear with me. I know there is a lot of security flaws, and tricks to make this much more compact and clean. I'll do that latter.

Right now, functionality is numero uno :)

Important Source Code:

Code:

---

    int maxC;
    int max1;
    int max2;
    int max3;
    int max4;

  char a1[3] = "  ";
  char a2[3] = "  ";
  char a3[3] = "  ";

                for (; max1>0; )
                {
            compare = strcmp(a1,"  ");
                        if (compare==0)
                        {
                  a1 = "..";
                  max1= max1 - 2;
                  continue;
                        }
                       
            compare = strcmp(a2,"  ");
                        if (compare==0)
                        {
                  a2 = "..";
                  max1= max1 - 2;
                  continue;
                        }
                       
            compare = strcmp(a3,"  ");
                        if (compare==0)
                        {
                  a3 = "..";
                  max1= max1 - 2;
                  continue;
                        }
              }

The error says what it says: you are not allowed to assign to an array. What you can do is use strcpy, memcpy and the like to copy the content.

Also, the error message mentions C++, which probably means that you are using a C++ compiler to compile your C program. While this is not necessarily wrong, it is probably not what you want to do.

Very interesting, I'm on page 321 of 358, and what do you know, strings are the last section.

Just learned a string is just an array of characters, which explains the error code and my confusion. Used strcpy and works perfect. I am aware of the C++ compiler problem. Will fix it when I have the patience. Thanks a bunch! :)

What compiler are you using? There usually is a simple solution for this.

Bloodshed Dev-C++. I tried uninstalling it and putting in mingw but it just gave me a bunch of problems.

DevC++ has been abandoned for at least 6 years. The compiler supplied with it is at least 7 years out of date...

Why are you playing with Abandonware when there are several free and up-to-date compilers readily available on the net...

I usually recommend Pelles C for C-99 ... no C++ crap to get in the way, 32 and 64 bit compilers and the best help file you could ask for.
