程序代码：

#include <stdio.h>
#include <limits.h>

int main()
{
    printf("Hello world!\n");
    printf("Size of Char %d\n",CHAR_BIT);//CHAR_BIT表示char类型用多少位来表示；
    printf("Size of Char max %d\n",CHAR_MAX);
    printf("Size of Char min %d\n",CHAR_MIN);
    printf("Size of Int max %d\n",INT_MAX);
    printf("Size of Int min %d\n",INT_MIN);
    printf("Size of Long max %ld\n",LONG_MAX);
    printf("Size of Long min %ld\n",LONG_MIN);
    printf("Size of Short max %d\n",SHRT_MAX);
    printf("Size of short min %d\n",SHRT_MIN);
    printf("Size of unsigned char %u\n",UCHAR_MAX);
    printf("Size of unsigned long %lu\n",ULONG_MAX);
    printf("Size of unsigned int %u\n",UINT_MAX);
    printf("Size of unsigned short %u\n",USHRT_MAX);

    return 0;
