<The C programming language> 语言测试

测试以下内容：

1、三字符序列；

2、wchar_t

3、打印输出g/p/o/x

#include <stdio.h>#include <math.h>int main(void){double a;int *pi,buf[20];int no;wchar_t chi;chi = '鬼';printf("鬼 = %c\t??=#??/n%d\n",chi,chi);pi = buf;for(int i = 0;i < 20;i++){a = 0.123456789 * pow(10,i-10);pi??(i??) = i;printf("%.*g\n%n",i,a,&no);printf("%d char%s been typed.\n",no,(no > 1) ? "s have" : " has");printf("i = %d = ox%04x = 0%04o\n",*(pi+i),i,i);printf("*pi is stroed in the address: %p\n",pi + i);}}
