C - a pseudo-interpreter of the C programming language


    C, the pseudo-interpreter, has several advantages over other
    scripting languages, such as perl.

        very fast (100x faster than perl when calculating fib(40))
        easy handling of binary data
        good for testing system calls and C APIs

    To install,copy the downloaded file to /usr/bin, and chmod 755.

    Below are some examples.

    % C -e 'printf("hello world\n")'
    hello world
    % C -cO3 -e 'int fib(int i) { return i > 2 ? fib(i-1) + fib(i-2) :
     1; } printf("%d\n", fib(40))'
    102334155

    % C -e 'int t, sum = 0; while (fread(&t, sizeof(int), 1, stdin) ==
     1) sum += t;printf("%d", sum)' < data
    31289

    % cat hello.C
    #! /usr/bin/C

    printf("hello world\n");

    % ./hello.C
    hello world

真是太強大了...orz|||
