Question

VC++6.0下运行如下程序：（我新建的工程选“win32 console application”,文件是“C++ source file" .

#include"stdafx.h"
#include<iostream.h>
int main(int argc,char*argv[])
{
int num1=0,num2=0; //定义全局变量num1,num2,并赋予初值
num1++; num2++; //将num1加1后赋给num1,将num2加1后赋给num2
cout<<"num1="<<num1<<","<<"num2="<<num2<<endl; //输出num1，num2的值
{
float num1=7.7 //定义局部变量num1
num1++;num2++;
cout<<"num1="<<num1<<","<<"num2="<<num2<<endl;
}
num1++; num2++;
cout<<"num1="<<num1<<","<<"num2="<<num2<<endl;
return 0;
}
按编译时，出现如下错误：Cannot open include file: 'stdafx.h': No such file or directory。
原因是什么？？？？？？

Answer 1

1 删除#include"stdafx.h"。
2 float num1=7.7 行尾加分号。

追问

missing ';' before identifier 'num1'，还是这样啊

追答

//粘贴下面的代码试试。
#include
int main(int argc,char*argv[])
{
int num1=0,num2=0; //定义全局变量num1,num2,并赋予初值
num1++; num2++; //将num1加1后赋给num1,将num2加1后赋给num2
cout<<"num1="<<num1<<","<<"num2="<<num2<<endl; //输出num1，num2的值
{
float num1=7.7; //定义局部变量num1
num1++;num2++;
cout<<"num1="<<num1<<","<<"num2="<<num2<<endl;
}
num1++; num2++;
cout<<"num1="<<num1<<","<<"num2="<<num2<<endl;
return 0;
}

Answer 2

float num1=7.7 //定义局部变量num1
后面加分号；

追问

加了
还是missing ';' before identifier 'num1'

Answer 3

把第一行的代码（#include"stdafx.h"）删掉即可，这个头文件是与MFC相关的在这里没用。
