    portable functions

    does anyone know the metroworks codewarrior equivalent for getch(); and clrscr();
    I'm doing an school assignment and the prob is that it has to compile using the school's out of date software. AND on a mac.

    Google turned this up, might be helpful.
    No No's:
    fflush (stdin); gets (); void main ();


    Goodies:
    Example of fgets (); The FAQ, C/C++ Reference


    My Gear:
    OS - Windows XP
    IDE - MS Visual C++ 2008 Express Edition


    ASCII stupid question, get a stupid ANSI

    Is clearing the screen and waiting for any keypress really a requirement? clrscr and getch are very out of date and the former is used by annoying programs. Have you looked for solutions in the FAQ?

    For clrscr you could alawys get the dimensions of the screen, and have a function which runs on a for-loop which would press return according to the number of rows there ... there is always this .... I recommend number 5 (for clearing screen)

    for getch(), you may be able to use some variation of kbhit(), but that's in conio too, I think, so it probably won't be any good for you

    You could create your own one ... but I don't know of any other getch();, or system("pause"); functions ... somebody else may ... you could make your own one ... my making a HUGE array of GetAsyncKeyState(); or whatever it's called ... search through here for examples, and try MSDN.

    You could also try this

    cin.get();

    It is used with iostream

    -pete

    cin::get() waits for the return key. getch() does not.
    Code:
    #include <stdio.h>
    
    void J(char*a){int f,i=0,c='1';for(;a[i]!='0';++i)if(i==81){
    puts(a);return;}for(;c<='9';++c){for(f=0;f<9;++f)if(a[i-i%27+i%9
    /3*3+f/3*9+f%3]==c||a[i%9+f*9]==c||a[i-i%9+f]==c)goto e;a[i]=c;J(a);a[i]
    ='0';e:;}}int main(int c,char**v){int t=0;if(c>1){for(;v[1][
    t];++t);if(t==81){J(v[1]);return 0;}}puts("sudoku [0-9]{81}");return 1;}
