Hi guys,
I'm writing a simple program which takes similar values from a user at the keyboard. But I've run into some issues and I'm not sure why. It MUST be to do with the conversion specifiers but I just can't figure it out :/
Here's the code:
/*
* File: main.c
* Author: daniel
*
* Created on March 27, 2012, 6:49 PM
*/
#include <stdio.h>
#include <stdlib.h>
#include "main.h"
#define MAX_LAT 52.75
#define MIN_LAT 51.5
#define MAX_LNG 6.5
#define MIN_LNG 4.75
#define REQ_LAT 0.1
#define REQ_LNG 0.2
/*
* This function takes a location value from the user and if any ships are
* within 0.1 latitude or 0.2 longitude of this position the function will produce
* a message and log the information appropriately
*/
int main(int argc, char** argv)
{
ship s; // struct in the headerfile containing latitude and longitude of type double
double user_lat;
double user_lng;
// THESE TOP TWO PRINTFS WILL BE REPLACED BY VALUES TAKEN FROM OUR
// DATA ENTRY PROGRAM
printf("Please enter a specific latitude value for the vessel: ");
scanf("%lf", s.latitude);
printf("%lf", s.latitude); //used for de-bugging
printf("Please enter a specific longitude value for the vessel: ");
scanf("%lf", s.longitude);
printf("Now enter a latitude area you'd like to check in: ");
scanf("%le", &user_lat);
printf("Now enter a corresponding longitude area you'd like to check in: ");
scanf("%le", &user_lng);
//IF LATITUDE/LONGITUDE VALUES OF THE SHIP ARE WITHIN
//USER'S GIVEN VALUES IN ACCORDANCE WITH THE REQUIRED LAT AND LNG
//PRODUCE A MESSAGE
// THIS LOOP WILL DEAL WITH WHETHER A SHIP IS WITHIN THE BOUNDARIES OF
// A USER'S CHOSEN LAT AND LNG VALUES AND ALSO DEAL WITH WHETHER OR NOT SHIP'S
// ARE EVEN IN St.George's CHANNEL AT ALL!
return (EXIT_SUCCESS);
}
Now the program runs and lets me enter the latitude and longitude figures but then produces the RUN FAILED error message.
For reference here's the output:
Please enter a specific latitude value for the vessel: 51.425
0.000000Please enter a specific longitude value for the vessel: 51.233
RUN FAILED (exit value 1, total time: 10s)
Anyone got any ideas? To me it should just at the moment take four values from the user :/
Thanks guys,
