在c环境下的对数据结构进行讲解,包含有例题及答案

 //str_lwr.cpp
 #include <iostream.h>					//cin,cout
 #include <conio.h>					//getch()
 #include <string.h>
 void main()
 { char st[]="Normal Distribution";		//字符串
   char str[]={'C','H','I','N','A','\0'};
   char *string = "abcdefghijklmnopqrstuvwxyz", *ptr;
   /* converts string to upper case characters */
   cout<<string<<"=>";
   ptr = strupr(string);				//返回字符串指针
   cout<<ptr<<endl;
   cout <<st<<"=>";
   strupr(st);						//以st返回
   cout <<st<<endl;
   cout <<str<<"=>";
   ptr = strlwr(str);					//转换为小写
   cout <<ptr;
   getch();
 }
