Can we use vector in C?

Vectors are a modern programming concept, which, unfortunately, aren't built into the standard C library. Vectors are same as dynamic arrays with the ability to resize itself automatically when an element is inserted or deleted, with their storage being handled automatically by the container.

Why do we use vector in C?

In C++, vectors are used to store elements of similar data types. However, unlike arrays, the size of a vector can grow dynamically. That is, we can change the size of the vector during the execution of a program as per our requirements. Vectors are part of the C++ Standard Template Library.

What can I use instead of vector in C?

Alternatives to Vector in C++.

array..

Deque..

Linked List..

multiset..

What is the use of vector in programming?

Vectors are used in many programming languages as data structure containers. They have a dynamic structure and provide programmers with the ability to allocate container size and memory space quickly. In this sense, vectors can be thought of as dynamic arrays.
