Amiga C++ vs PC version

[JJ__]

Hi All,

After typing in a relatively simple C++ program I found on the web and compiling it in Storm C version 3, I noticed that there are multiple compilation errors being flagged. The first line I was able to fix by looking at another program written in C++ on Storm C, but is there anywhere which has a list of Amiga specific versions of commands etc that map to more modern C++ usage?

The PC version program is shown here ... https://www.programiz.com/cpp-progra...raphical-order

The first line I was able to amend to "#include <iostream.h>" and it passed the compile test, but the second line "using namespace std;" Storm C didn't like and I've no idea how to fix it ... and then there are around 23 errors in total evidently for this program.

Cheers in advance for any help on this!

All of the native C++ compilers for the Amiga are pretty old.
If you want something more modern you will need to cross-compile.

I tried the first example on that page and it compiles and runs with Bebbo's GCC port.
https://github.com/bebbo/amiga-gcc

m68k-amigaos-g++ -noixemul -O2 test.cpp -s -o test

It's an 800Kb executable!

Thanks for the tip for the cross-compiler, but I wanted to actually program on my A1200 really instead of using a cross-compiler. I know it's old fashioned, but from the looks of it I'm going to struggle to develop for the Amiga natively sadly.

#include <iostream>
//using namespace std;

int main()
{
    std::string str[10], temp;

    std::cout << "Enter 10 words: " << std::endl;
    for(int i = 0; i < 10; ++i)
    {
      getline(std::cin, str[i]);
    }

    // Use Bubble Sort to arrange words
    for (int i = 0; i < 9; ++i) {
        for (int j = 0; j < 9 - i; ++j) {
            if (str[j] > str[j + 1]) {
                temp = str[j];
                str[j] = str[j + 1];
                str[j + 1] = temp;
            }
        }
    }

    std::cout << "In lexicographical order: " << std::endl;

    for(int i = 0; i < 10; ++i)
    {
       std::cout << str[i] << std::endl;
    }
    return 0;
}

"using namespace std;" is just a convenient way to not to write the class name each time it is used in the source.
I'm not sure that getline is available in storm C.

The 800k are taken by the c++ standard library.

you can save some bytes by specifying
