验证数据类型的字节长度

验证数据类型的字节长度

代码：

#include <stdio.h>
int main()
{
  char a;      //平常定义,输出时用%d  sizeof(a)  即可
  short int b;
  int c;
  long int d;
  float e;
  double f;
  printf("size of (char)=%d\n",sizeof(a));
   // printf("size of (char)=%d\n",sizeof(char));
   //printf(“%d”,sizeof(a));          //sizeof之间没有空格
  printf("size of (short int)=%d\n",sizeof(b));
  printf("size of (int)=%d\n",sizeof(c));
  printf("size of (long int)=%d\n",sizeof(d));
  printf("size of (float)=%d\n",sizeof(e));
  printf("size of (double)=%d\n",sizeof(f));
}
