Hi..
  Plz help me to solve this problem. This is about functions.

1. Write a program to print the following table.

Input lenght in inches &  output should be in lenght in 
mm,metre,feet. Have to use functions.
The prototype should be  

double mm(double inches);
double metre(double mm);
double feet(double inches);

.....................................................................
Inches      mm           m         feet
10          ....        ....        ....
20          ....        ....        ....
.
.
.
100         ....        ....        ....

.....................................................................

I wrote a program for this. But it gives errors. Can you correct my 
programme.

#include<iostream>
using namespace std;

double mm(double inches);
double metre(double mm);
double feet(double inches);

int main()
{
  double inches,mm,metre,feet;

  cout<<"mm"<<mm<<endl;
  cout<<"metre"<<metre<<endl;
  cout<<"feet"<<feet<<endl;

  for(int i=0; i<=100; i+10)
  cout<<i<<" "<<endl;

  return 0;

}
 
double mm(double inches)
double metre(double mm)
double feet(double inches)
{
  double mm,metre,feet,inches;

  mm=2.54*inches;
  metre=inches/12;
  feet=mm/1000;

}
