Differences between a Vector and an Array - A vector is a dynamic array, whose size can be increased, where as an array size can not be changed. - Reserve space can be given for vector, where as for arrays can not. - A vector is a class where as an array is not. - Vectors can store any type of objects, where as an array can store only homogeneous values. Advantages of Arrays: - Arrays supports efficient random access to the members. - It is easy to sort an array. - They are more appropriate for storing fixed number of elements Disadvantages of Arrays: - Elements can not be deleted - Dynamic creation of arrays is not possible - Multiple data types can not be stored Advantages of Vector: - Size of the vector can be changed - Multiple objects can be stored - Elements can be deleted from a vector Disadvantages of Vector: - A vector is an object, memory consumption is more.   if any doubts or queries please comment 

What is a structure? A structure is a user defined data type in C/C++. A structure creates a data type that can be used to group items of possibly different types into a single type. How to create a structure? ‘struct’ keyword is used to create a structure.

The order of declaration is followed. struct Point p1 = {0, 1}; cout<<"value of x="<<p1.x<<"value of y="<<p1.y; }   if any doubts or queries please comment 

INTRODUCTION I have made project “ Typing speed tester “. In this software we can test our speed and efficiency for typing via general keyboard.
