ctoyeet

C obfuscator made as a joke that converts a C syntax to 'yeet' looking syntax

It can convert itself! (if combined in a single file)

$ gcc yeet.c -o out # compile original
$ ./out yeet.c      # convert
$ gcc out.c         # compile yeeted source
$ ./a.out yeet.c    # use that to convert the original
$ ...               # and so on

Has some limits:

• Works only on single files for now
• #defines in the middle of the code break it
• probably bunch of other things

Features

Convets this:

char *generate(int n)
{
    n++;
    int bit = 16;
    int yeet_size = 4;
    while (bit <= INT_MAX) {
        if (n < bit) break;
        bit <<= 1;
        yeet_size++;
    }
    
    char *yeet = (char*) malloc(sizeof(char) * yeet_size);

    int capital;
    for (int i = 0; i < yeet_size; i++) {
        capital = n % 2; // first right bit
        if (i == 0) {
            yeet[i] = capital ? 'Y' : 'y';
        } else if (i == yeet_size - 1) {
            yeet[i] = capital ? 'T' : 't';
        } else {
            yeet[i] = capital ? 'E' : 'e';
        }

        n >>= 1;
    }

    return yeet;
}
