这是g＋＋的有关问题吗？还是…
这是g＋＋的问题吗？还是……
我在suse11.2下的g++4.4.1运行C＋＋程序，出现以下错误，是什么原因？？怎么解决？？？？
test.cpp: In function ‘int main()’:
test.cpp:8: error: ‘stdin’ was not declared in this scope
test.cpp:8: error: ‘freopen’ was not declared in this scope
test.cpp:12: error: ‘memset’ was not declared in this scope
------解决方案--------------------
你缺了这几个函数的头文件...
------解决方案--------------------
楼主，你这是学C++呢，还是学C啊？
------解决方案--------------------
#include <stdio.h>
#include <mem.h>
------解决方案--------------------
C和C++搅合一起了

#include <iostream>

#define max 100000
using namespace std;
int num[max];
int main()
{
freopen("in.txt","r",stdin);
int n;

memset(num,0,sizeof(num));
int m=(n+1)/2;
int a,answer;
for(int i=0;i<n;i++)

if(num[a]>=m)
answer=a;

cout<<answer<<endl;
