C++用whlie循环，1.求s=1+2+3+4+.....+10 2.求s=1+1/2+1/3+.....1/100的程序

1. 求s=1+2+3+4+.....+10的程序：

#include <iostream>
using namespace std;

int main() {
    int i = 1, s = 0;
    while (i <= 10) {
        s += i;
        i++;
    }
    cout << "s = " << s << endl;
    return 0;
}

输出结果为：s = 55

2. 求s=1+1/2+1/3+.....1/100的程序：

#include <iostream>
using namespace std;

int main() {
    int i = 1;
    double s = 0;
    while (i <= 100) {
        s += 1.0 / i;
        i++;
    }
    cout << "s = " << s << endl;
    return 0;
}

输出结果为：s = 5.18738
