模板

#define int long long

template<typename type>inline void fin(string intype,type &x){intype=((intype=="%d")?"%lld":intype);scanf(intype.c_str(),&x);}
template<typename type,typename... Args>inline void fin(string intype,type &x,Args&... args){intype=((intype=="%d")?"%lld":intype);scanf(intype.c_str(),&x);fin(intype,args...);}

使用事例

#include<bits/stdc++.h>
#define int long long
using namespace std;
template<typename type>inline void fin(string intype,type &x){intype=((intype=="%d")?"%lld":intype);scanf(intype.c_str(),&x);}
template<typename type,typename... Args>inline void fin(string intype,type &x,Args&... args){intype=((intype=="%d")?"%lld":intype);scanf(intype.c_str(),&x);fin(intype,args...);}
signed main()
{
	int a,b;
	fin("%d",a,b);
	printf("%lld",a+b);
	return 0;
