How to write C program without operater?

Answer 1

// a complete C program without using any operators

int main() {

return 0;

}

// a non-useless program, which accepts a single command line argument and

// prints whether or not the first character is a vowel

int main(int argc, char** argv) {

if(argc != 2) {

return 1;

}

switch(argv[1][0]) {

case 'a':

case 'e':

case 'i':

case 'o':

case 'u':

printf("vowel\n");

break;

default:

printf("not vowel\n");

}

return 0;

}
