c_cpp 使用命名的枚举作为字节

Posted 2021-05-14

#include <stdio.h>
#include <stdlib.h>

//attempt to use an enum as unsigned char 

enum NamedByte {
  ADD,
  SUB,
  MUL
};

typedef enum NamedByte NamedByte;

int main(void) {
  unsigned char* bytes = malloc(sizeof(unsigned char) * 10);
  bytes[0] = ADD;
  bytes[1] = SUB;
  bytes[2] = MUL;
  bytes[3] = MUL;
  for(size_t i = 0; i< 10; i++) printf("The number is %u\n", bytes[i]);
  return 0;
}
/*The number is 0
The number is 1
The number is 2

The number is 0
The number is 0
