void main ()
{
    int sum = 0;
    for(int i=1;i<=10;i++)
         sum += i;

    printf("sum:%d.", sum);
}

回复楼主小桥滴水

#include<iostream>
using namespace std;
void main()
{int sum=0,i=1;
while(i<10)
{i=i+1;
sum=sum+i;
}
cout<<sum<<endl;
}

程序代码：

#include <iostream>
#include <vector>
#include <algorithm>

using std::cout;
using std::endl;
using std::vector;
using std::for_each;

const int N = 10;

int main(void)
{
    vector<int> a(N);
    int i = 1;
    int sum = 0;
    for_each (a.begin(), a.end(), [&i] (int& a) {a = i++;});
    for_each (a.begin(), a.end(), [&sum] (int& a) {sum += a;});
    cout << sum << endl;
    return 0;
}

据说这才是C++

哦编译要用高版本的编译器比如我用的
gcc --version
gcc.exe (rev1, Built by MinGW-builds project) 4.8.1

编译参数
g++ -Wall -std=c++11 a.cpp

#include<iostream.h>
int main（）
｛int sum=0，i;
for（i=1;i<11;i++）
sum+=i;
count<<sum<<endl;
return 0

｝
