Hi, i'm making a C program for class and i have everything done but i get an error which i cant find the fix for, any idea what might cause the error?
The program converts Dates from the julian calendar to the georgian calendar.
| code: |
#include <stdio.h>
#include <math.h>
/*Define Function JD for later use in the program */
double JD(double date);
main()
{
int valid=1;
double J_date;
printf("======= JULIAN DATE CONVERTER =========\n");
/* gets input from user */
printf(" Enter the Julian date number, number must be bigger than 2299160)\n");
scanf(" %lf ", &J_date);
/* Check to see if proper date was entered */
while( valid != 0 )
{
If(J_date > 2299160)
{
valid=0;
}
else
{
printf("Wrong number inserted please enter a number bigger than 2299160\n");
scanf(" %lf ", &J_date);
}
}
/* Calls the function JD */
double JD(J_date);
}
/*
A new function named JD,
Does the convertion from Julian date
To Gregorian Date
*/
double JD(double date)

first error that crops up:
| code: | [john@saxifrage test]$ gcc test.c
test.c: In function 'main':
test.c:32: error: expected ';' before '{' token
test.c:45: warning: parameter names (without types) in function declaration |
After that there are any number of small errors in your code, such as incomplete code blocks ( {} bits). There are lots of logic errors too, including an infinite loop. Then there is the function call at the end of main which isn't valid. I think you may need to read up on functions.
because I am feeling generous here is some mostly working code, I've changed it so it won't output the right thing; just so you can't copy it outright
