If you make your variable names short enough, you can just make them an all-lowercase string [a-z0-9]+ and not worry about CamelCase or underscores or minuses

If you name your variables things like x, y, c, i, eu, ev, gorp, then you don't have to worry about CamelCase

eu, ev, and gorp are from actual code (not written my me!), by the way

@vaporeon_ what is gorp

@wallhackio UNIXv7, /usr/src/cmd/size.c:

#include    <stdio.h>
#include    <a.out.h>

/*
    size -- determine object size

*/

int a_magic[] = {A_MAGIC1,A_MAGIC2,A_MAGIC3,A_MAGIC4,0};

main(argc, argv)
char **argv;
{
    struct exec buf;
    long sum;
    int gorp,i;
    FILE *f;

    if (argc==1) {
        *argv = "a.out";
        argc++;
        --argv;
    }
    gorp = argc;
    while(--argc) {
        ++argv;
        if ((f = fopen(*argv, "r"))==NULL) {
            printf("size: %s not found\n", *argv);
            continue;
        }
        fread((char *)&buf, sizeof(buf), 1, f);
        for(i=0;a_magic[i];i++)
            if(a_magic[i] == buf.a_magic) break;
        if(a_magic[i] == 0) {
            printf("size: %s not an object file\n", *argv);
            fclose(f);
            continue;
        }
        if (gorp>2)
            printf("%s: ", *argv);
        printf("%u+%u+%u = ", buf.a_text,buf.a_data,buf.a_bss);
        sum = (long) buf.a_text + (long) buf.a_data + (long) buf.a_bss;
        printf("%Db = 0%Ob\n", sum, sum);
        fclose(f);
    }
}

@wallhackio They're saving the original value of argc in gorp before processing the arguments. No idea why they named it gorp.
