I am VERY new to C++ and was wondering if someone could help me write this program. I am trying to find the area and perimeter of a rectangle. The length is 10 and the width is 12. Area = length * width (i am presuming) and Permiter would = 2 * length + 2 * width.

Most appreciated 21st century invention of language program you can say. Ans there is so many updates in this program as latest ones, like every time need to be in touch to learn new things in it as my point of view.

Michel I think you need to be with online tutorial for this error. First of all just make a glance to manual training resources that is much better as my point of view.

C + + is a programming language so it's hard for a program that generates the error to run the program every time when I need help with C + + and resolve this error because of additional proposals and tutorials as well as the function, cycle, string, string is out. It 's more used to help in C + +.

Allocate a new array of the desired size, copy over the appropriate elements from the old array, then delete the old array.

C++ is a programming language thus it have a more difficult program that create a error during run this program at that time we will be need a help in C++ and solved error because more suggestion and tutorials of a function, loop ,array,string in help. It is a more used help in C++.I want help about how to do the database connection in C++? is this allowed?

1.define pointer variable *a assign null value to it
2.then define variable that (example n) to store size of arrays input by a user.
3. save pointer in variable a allocate array using new opreater.(a=new int[n])
4.then u need loop for up to n numbers to initialize element(for(int i=0;i,n;i++)
{
a[i]=0;
}
this will initialize all elements.
and finally you can free memory that is used by pointer.
by delete[]a;
this way you can create array dynamically

It is very canonic thing and from which your will ameliorate your analytic also.there are so gobs Books and sessions are uncommitted for that from which you can get the estimates about all the topics.
