Displaying symbols in C++

[Shimergloom]

Just need to know how to display symbols in a C++ console application. In particular I need to display °. Tried pasting one in but it shows up as a shaded space in the console.
I know it's a simple thing, but I'm still learning. Help is much appreciated.

The console only supports certain characters.

So that's a "you can't"?

Depending on the OS you're writing your program for, your terminal has to use the correct encoding for any non-ASCII characters and the font should contain the symbol you're trying to render.

In any case, special characters are best written using their hex-code, i.e. 0xA7.

How would I go about finding the hex-code for °? (the degree symbol)

I think you need to set the output to hexadecimal, although I'm neither sure how to do this or if you need to.

The same way you'd do it in plain C:

#include <stdio.h>

int main(int argc, char** argv)
{
        printf("Here we've got a char...: %c\n", 0xBA);
        printf("Here we've got a char...: \xBA\n");

        return 0;
}

{
        printf("Here we've got a char...: %c\n", 0xBA);
        printf("Here we've got a char...: \xBA\n");

        return 0;
}

Don't know how to do it in plain C and that makes very little sense to me. ^^;

I'm guessing you are using iostream. Try learning to use printf. What he did is he took the characters hexadecimal value and used a "variable"(%c). The %c is replaced with the 2nd argument.
