你代码呢

你代码会编译错误的原因是因为：你的数组和变量重名了，都叫a。

改成这样就行了：

#include<iostream>
#include<algorithm>
using namespace std;

struct st{
    int g,l;
} c[5005];

bool cmp(st x,st y)
{
    return x.l < y.l;
}

int main()
{
    int n,s,a,b;
    cin>>n>>s>>a>>b;
    for(int i = 1;i <= n;i++)
    {
        cin>>c[i].g>>c[i].l;
    }
    sort(c+1,c+n+1,cmp);
    int cur = 1,ab = a+b,ans = 0;
    for(;cur <= n;cur++)
    {
        if(ab >= c[cur].g&&s>=c[cur].l) 
        {
            s -= c[cur].l;
            ans++;
        }
    }
    cout<<ans<<endl;
    return 0;
}
