Question

i need to write a geometric series in c program, its like you take a step and each new step is half the previous step and how far travelled after 5 steps?

Answer 1

I can't help with the syntax, but did you make an algorithm for it yet?

Answer 2

Here's a recursive function that will do it:
```
/* Recursive function to calculate the distance travelled
* in number of steps ( numSteps ) that start out being
* ( length ) long. Each step is half the length of the
* previous step.
*/
float doStep( int numSteps, float length )
{
if( numSteps )
return( doStep( --numSteps, length / 2 ) + length );
else
return( 0 );
}
```
