I need help on doing this program. It's for school and I'm stuck and don't know how to code it. This is what I have to do:

Write a program that asks the user for a weight in pounds (lbs) and ounces (oz), and prints out the total weight in pounds and in kilograms. Use the conversion factor of: 1 pound = 16 ounces, and 1 pound = 0.45 kilogram.

When prompting the user for an input value, prompt for a non-space separator between the pounds and ounces. The separator can be a comma, a dash or any reasonable character, as long as its not a space or tab or new line character.
The pounds and ounces must be read in as integer data.

Sample program output:
Enter weight (format: lbs, oz): 10, 15
Weight in lbs: 10.94
Weight in kgs: 4.92

For the program output:
- Print the result with only 2 digits after the decimal point.
- The 2 weights should be in column format, right justified

When calculating the weight, dont forget that the result of the calculation should be floating point number.

This program must be done following this structure chart:
(Try to ignore the ''')

'''''main
''''|
-----------------------
|-----------|-----------|
getInput''''calculate''''printOutput
'''|
''----
''''' |'''|
''topounds''tokilogram

So far I've gotten this:

#include <stdio.h>

int getinput (void)

{
int pound;
int ounces;
char seperator;

printf ("Enter a pound, a seperator, and a ounce: ");
scanf ("%d %c %d", £, &seperator, &ounces);
return;
}

int calculate (int*pound, int*ounces)
{
int founces;
int fpounds;
int kilogram;

founce = (float) ounces;
fpounds = pounds + (founces / 16);
kilogram = fpounds * 0.45f;

return;
}

int printoutput (int*fpounds, *int*kilogram)
{
printf ("weight in lbs: %.2f\n", fpounds);
printf ("Weight in kqs: %.2f", kilogram);
return 0;
}

Please help me out. Thanks.
