Help with a basic C program to convert temperatures
I am trying to do a conversion program for temperatures, and will attach all files I have below, however I am having some difficulty.
Whenever I try to compile the convert.c file in UNIX i get the following message:
convert.c:32:2: warning: no newline at end of file
This is the first time I have ever really worked with C. Here is all my codes:

i changed it to printf and now it prints out
cent_to_fahr(cent) and vice versa rather then the actual conversion!
cent_to_fahr(cent) and vice versa rather then the actual conversion!

This is the changes I made to the convert.c file it compiles and runs however, it is giving to many spaces and I am unfamiliar wih formatting the scanf command.
#include <stdio.h>
#include "fahr_to_cent.c"
#include "cent_to_fahr.c"
main()
{
int choice;
double fahr;
double cent;
printf("Welcome to the Temperature Conversion Program\n\n");
printf("1 - Fahrenheit to Celsius\n");
printf("2 - Celsius to Fahrenheit\n");
printf("_________________________\n");
printf("Your choice is? : ");
scanf("%d", &choice);
if(choice == 1)
{
printf("Please enter then temperature in Fahrenheit: ");
scanf("%lf", &fahr);
printf("%lf degrees Fahrenheit is %lf degrees Celcius. \n", fahr, fahr_to_cent(fahr));
}
else
{
printf("Please enter the temperature in Celsius: ");
scanf("%lf", ¢);
printf("%lf degrees Celcius is %lf degrees Fahrenheit. \n", cent , cent_to_fahr(cent));
}
return 0;

for example if I only wanted it to print until it reached a zero could I do that:
as in 32.45 printing as 32.45 instead of 32.450000 and on the same line116.010000 would come out 116.01
as in 32.45 printing as 32.45 instead of 32.450000 and on the same line116.010000 would come out 116.01

right but if I do .%.2lf then it prints two decimal places to the left but if there were none then I still get 0's and if there were more then it cuts of the end.
so for example
45 prints 45.00
45.1 prints 45.10
and 45.234 prints 45.23
I would like to print 45 as 45, 45,1 as 45,1 and 45.234 as 45.234
if possible
so for example
45 prints 45.00
45.1 prints 45.10
and 45.234 prints 45.23
I would like to print 45 as 45, 45,1 as 45,1 and 45.234 as 45.234

Then u need to take anothr double variable to store the value and need to convert it to a string.Then using pointer you need to verify what value to keep and then convert the resulting string to double...
