如何屏蔽警告warning: initialization discards 'const' qualifier

Question

如何屏蔽警告

warning: initialization discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]

code如下

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

int main(void) {
  const char* codec = "PCM";
  char *new_codec = codec;
  printf("%s\n", codec);
  return EXIT_SUCCESS;
}

在编译时出现上面的警告,运行正常

我知道一个办法new_codec添加const关键字定义
还有没有其他办法

Answer 1

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

int main(void) {
  const char* codec = "PCM";
  char *new_codec = (char *)codec;
  printf("%s\n", codec);
  return EXIT_SUCCESS;
}
