Program is not compiling

[buntybutt]

Hi there!
I just started to learn C++ and wrote a simple program to radius from user and than calculate the Area, Circumference and Diameter, but the problem is it's not executing and I tried my best to get rid of the error, but in vain.
Please help me to get it executed.
Here is the program code

#include<iostream.h>
main()
{
      float radius;
      float diameter;
      float circumference;
      float area;
      cout<<"Please enter the radius of a circle:";
      cin>>radius;
      diameter=2*radius;
      circumference=2*3.14*radius;
      area=3.14*raidus*radius;
      cout<<"diameter of Circle is:";
      cout<<diameter;
      cout<<"circumference of Circle is:";
      cout<<circumference;
      cout<<"area of Circle is:";
      cout<<area;
}

Please tell me where is error in this program.
Thanks

Line 1, the standard header file is iostream not iostream.h You would then need a statement using namespace std; to use all the symbols it contains.

Line 2, main returns int not nothing

Line 13, you have misspelt radius as raidus

Line 14 - 19 you do not output any newlines or spaces so the output comes out on 1 line in a very unreadable format.
