#include <stdio.h>
 void main()
 {
     int a=0;
     int b=0;
     a++;
     b++;
     printf("int",a,b);
     {
         float a=0.5;//定义局部变量
         a++;
         b++;
    printf("int",a,b);
     }
     a++;
     b++;
     printf("int",a,b);
 }

输出的结果错误，这个是由C++改写的，我就是输出那里不会，这是本来的C++代码：#include <iostream.h>
 void main()
 {
     int a=0;
     int b=0;
     a++;
     b++;
     cout<<"a="<<a<<","<<"b="<<b<<endl;

     {
         float a=0.5;//定义局部变量
         a++;
         b++;
         cout<<"a="<<a<<","<<"b="<<b<<endl;
     }
     a++;
     b++;
     cout<<"a="<<a<<","<<"b="<<b<<endl;
 }

谈论啊
