For reading a vector or any STL in C++ I was initialliy using a marco
#define read(x) for(auto &inps: x) cin>>inps
int n = 5;
vector<int> a(n),b(n),c(n);
read(a);
read(b);
read(c);
But for reading multiple vectors I want to implment a kind of function or macro that does something like
int n = 5;
vector<int> a(n),b(n),c(n);
read(a,b,c);
Can someone help me that how to implement this? I have tried to implement this using templates and macros but i am facing error. Here I have attached the code that I had implemented.
#define read(args...) read1(args)
template<typename T, typename... Args>
void read1(T &a, Args... args) {
for(auto &i:a) cin >> i;
read1(args...);
}
