c_cpp 在c中移动一个字节指针

Posted 2021-05-14

#include <stdio.h>

//move byte pointer in c


void move_ptr(unsigned char** ptr)
{
  *ptr += 1;
}


int main(void) {
  unsigned char code[4] = {1, 2, 3, 4};
  unsigned char* cptr = code;
  move_ptr(&cptr);
  for(int i=0;i<4;i++) printf("%u\n", cptr[i]);
  return 0;
}
