帮助比较argv字符串

Question

我有:

int main(int argc, char **argv) {
   if (argc != 2) {
      printf("Mode of Use: ./copy ex1\n");
      return -1;
   }

   formatDisk(argv);
}

void formatDisk(char **argv) {
   if (argv[1].equals("ex1")) {
       printf("I will format now \n");
   }
}

如何检查C中argv是否等于"ex1"？是否已有功能？谢谢

Answer 1

#include <string.h>
if(!strcmp(argv[1], "ex1")) {
    ...
}
