Flags (or compiler options) are nothing but ordinary command line arguments passed to the compiler executable. Assuming you are invoking g++ from the command line (terminal): $ g++ -std=c++11 your_file.cpp -o your_program or $ g++ -std=c++0x your_file.cpp -o your_program if the above doesn’t work.
The C++ FAQ has a list of possibilities: Is it possible to convert C++ to C?. In short, it says that you can’t expect this to give you particularly readable code. Think of the complexities involved; multiple inheritance, virtual-function resolution, templates, operator overloading, etc., etc. There’s no clean succinct way of expressing these concepts in pure C. If … Read more
You are using growthRate both as a variable name and a function name. The variable hides the function, and then you are trying to use the variable as if it was the function – that is not valid. Rename the local variable.
Pointer to an integer value Pointer to a pointer to an integer value (Ie, in the second case you will require two dereferrences to access the integer’s value)
At worst, your lecturer is wrong. At best, he was simplifying terminology, and confusing you in the process. This is reasonably commonplace in software education, unfortunately. The truth is, many books get this wrong as well; the array is not “passed” at all, either “by pointer” or “by reference”. In fact, because arrays cannot be passed by … Read more
This is almost certainly due to a missing dependency. Use a tool like Dependency Walker to find the required dependencies of the DLL. Or, if the DLL is supplied by a third party, read their documentation which should specify the required dependencies. Note that Microsoft.VC90.ATL indicates version 9 of MSVC which is VS2008. So you would need to install … Read more
Ok my edit solved the problem: placing a dash – in front of include hides the error messages coming from the dependency generation. Note for later: don’t try to outsmart Make.
This seems to be answered – #include <fstream>. The message means :- incomplete type – the class has not been defined with a full class. The compiler has seen statements such as class ifstream; which allow it to understand that a class exists, but does not know how much memory the class takes up. The forward declaration allows the … Read more
I think you want this: To look like this: It looks like you lost track of your scope immediately following the else.
If you have the values in a vector or an array, just use std::accumulate from <numeric>:
