Write a program which include class to represent a vector(a serious of float values). Include member functions to perform the following tasks:
a> To create the vector
b> To modify the value of given elements
c> To Display the given vector in the form (10,20,30)

Code : 

 #include<iostream.h>  
 #include<conio.h>  
 #include<process.h>  
 class vector
