Slicing of a array

#1

How can we do slicing of an array or list like we do in python…both for int and character type array

#2

hello @prerak_semwal
there are various ways.

like u can use copy function
or range constructors
or inbuilt slice function.

example->

// Function to slice a given vector
// from range X to Y
vector<int> slicing(vector<int>& arr,
                    int X, int Y)
{
  
    // Starting and Ending iterators
    auto start = arr.begin() + X;
    auto end = arr.begin() + Y + 1;
  
    // To store the sliced vector
    vector<int> result(Y - X + 1);
  
    // Copy vector using copy function()
    copy(start, end, result.begin());
  
    // Return the final sliced vector
    return result;
}

pls refer this for examples of other methods -> link

I haven’t learned about vectors is there any other way … talking w.r.t character arrays ,int arrays, string objects (in string library)

there are function like substr that u can use to slice ur c++ string.
for char array read about functions like strncpy ,memcpy function.

for int array u need to deal it manually , i dont have any function in my mind.
