How to make multiple vectors ?
We generally make vectors using – vector<int> vector_name;
But any method to make multiple vectors at once ?

>Solution :

I assume that you’re trying to create multiple vector at once and store them. You can use a simple for loop, or use a vector of vectors!
For example:

#include <vector>

// Using a for loop
#define VECTOR_COUNT 5
std::vector<int> myFiveVectors[VECTOR_COUNT];
for(int i = 0; i < VECTOR_COUNT; i++)
    myFiveVectors[i] = {1, 2, 3};

// Using vector of vectors
std::vector<std::vector<int>> myVectors{};
myVectors.push_back({1, 2, 3});
