    Compile C++

    I can compile following code using "cl A.cpp" but i want to compile with an input file and generate output file A.out.. is there any why to do that from cmd....


    int main(){
        int n;
        while( scanf("%d", &n) ){
            if( !n )break;
            printf("%d\n", n);
        return 0;

    Well.. you could use redirection.
    Write your program to use cout and cin(or printf and scanf..) for I/O ..and then.. when running; use the command.
    ./executable <input_file >output_file
    But how you got the idea that you can compile with file and produce A.out `s is 'suspicious' ! ..(If you saw a.out as the executable... then remember that it is just an executable format...not something your program produces. )

    What did you not post this in the C section?

    Outside of your DOS world, your header file is meaningless.

    You could, but what you've written is all C.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
