A C-Language Problem ...

Question

I'm especially counting on the help of computer programmers out there.

Please give me a program that can compute the circumference of a circle using the const keyword.

Thank you!

Answer 1

perhaps i can help. but i need more info than what you just provided.

Const is only a data type.

for example

int a=10; makes a=10.

but I am allowed define a=12 later in the program. Therefore the value 10 is not hard coded to that memory variable.

Where as const b=5; sets b as 5. no exceptions.

Do you just simply want a program to compute the circumference of a circle?

I think I u/stand your problem a bit though you are not very clear. You need to understand the question properly.

In case of a circle, the value of (pi) is a contant 3.14 or (22/7) . And your equation for computing the circumference would be 2*pi*r where 'r' is the radius of the circle?

Hence your program would be this way,

#include <stdio.h>

#include <conio.h>

main()

{

clrscr();

int r;

const float pi=3.14;

cout<< "]\n Enter radius  \t : ";

cin>>r;

cout<< "\n\n Circumference \t = "<<"2 * pi * "cout<<r<<" is : "<<2*pi*r;

getch();

}

hope this helps. :)
