Super easy question, I'm trying to compare argv[1] to a the string "-d" and I'm not having any luck on correcting comparing them. What is the correct way to compare a argv[1] to a string?

#include

#include

#include

#include "pgm.h"

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

if (argc == 4) {

int ret2;

ret2 = strncmp(argv[1], "-d", 2);

printf("%s ",argv[1]);

printf("%d ",ret2);

if (ret2 == 0){

printf("ret2");

}

}

else {

printf("%s","Error ");

return 0;

}

return 0;

}

//Read( argv[1] , argv[2] );
