Dev C++ 4.9.9.2 error code

[dan3260]

I have got a couple error codes and i am new to this so i do not know what they mean. Any help would be appreciated. I am using Dev C++ v4.9.9.2

1) [Warning] comparison is always true due to limited range of data type
[Linker error] undefined reference to `Save(int, char*)'

2) ld returned 1 exit status

The comparison-always-true warning message should include a line number pointing to the problem. I generally see this error for something like the following:

unsigned int a;
...
if (a >= 0)
...

The comparison is always true because an unsigned type can never be negative. Take a look at the indicated line and look for something like that.

The linker error indicates that function Save isn't present. Is this a function you wrote (if so, link in that object file) or is it a library function (if so, bring in the necessary library).
