This is the most naïve approach to initialize a vector. Firstly, we just define an empty vector. At that point, it has no idea about how many elements it’s going to have. Then by usingpush_back()function we can simply keep adding elements at the back as per requirement. Example Be...

Moving on to the main function, we initialize an existing vector of Person structs named parr1 using the initializer list constructor. This constructor allows us to directly populate the vector with instances of the Person struct, each specified within a set of curly braces. The new vector parr...
initialization of vector takes a fixed size of inputs via a constructor or any method. This can be done in five different ways: we can initialize a vector using an existing vector, array while creating an object, and most importantly, using...
