I haven't done much with passing array's around in C++ in a while and things were going fine until just recently when I started getting the following error:
1>Sort_Comparison.obj : error LNK2001: unresolved external symbol "int * x" (?x@@3PAHA)
1>Sort_Comparison.obj : error LNK2001: unresolved external symbol "int * temp" (?temp@@3PAHA)
Any help at all would be much appreciated in resolving the problem
pointers ("arrays" in your case, i guess) are built into the language, so you shouldnt have a problem just because your using pointers. if im correct, it looks like your programming with some library but you arent linking to it. do you know what compile and link arguments your passing to the compiler? a little more detail as to what files you have, which library your using, etc., might help too.
I don't think it'll be a missing library. You get a linker error like that if you provide some extern definitions for a variable but don't actually declare that variable anywhere. Usually the header file has the extern definition and the cpp file has the actual declaration.
Post the code that you think is the declaration of the above two variables.
I declare them with:
int x[100000];
int temp[100000];
and later change the size of the arrays in a series of if statements
If you declare them like that, you can't "later change the size" of those arrays.
