使用转换说明符％c将char类型输出为字符

％c转换说明符将变量的内容输出为单个字符。％d说明符将其解释为整数。

#include <stdio.h>

int main(void)
{
  char first = 'T';
  char second = 63;

  printf(The first example as a letter looks like this - %c\n, first);
  printf(The first example as a number looks like this - %d\n, first);
  printf(The second example as a letter looks like this - %c\n, second);
  printf(The second example as a number looks like this - %d\n, second);
  return 0;
}
