Question

c++编写的输入两个数a，b，让其从a加到b，帮忙看一下哪里有错误？谢谢。

#include "stdafx.h"
#include<iostream>
int main()
{
std::cout << "请输入两个数:" << std::endl;
int a = 0, b = 0, c = 0, d = 0;
std::cin >> a >> b;
while (c >= b) {
d = c + a;
c = a + 1;
}
std::cout << a << "加到" << b << "等于" << d << std::endl;
return 0;
}

哪里看呢？？试写了一下

#include<iostream>
using namespace std;
int main(){
	int a,b,i,sum=0;
	cout<<"input a and b"<<endl;
	cin>>a>>b;
	for(i=a;i <= b; i++){
		sum+=i;
	}
	cout<<sum;
}

追问

能帮我看看我上边写的那个哪里不对行吗？
