This constructor allows us to create a new vector and initialize it with the elements from an existing range, such as another vector. The syntax for using the range constructor to initialize a vector of structs is as follows: std::vector<StructType> newVector(existingVector.begin(), existing...

The push_back() function is declared inside the <bits/stdc++.h> and the <vector> header files. The syntax for this particular function is as follows:vector.push_back(value); In the above syntax, the term vector represents the vector to which we have to add elements. This function ...
