Problems reading entered race times C
Whenever I enter a race time say 3.20 (for 3hrs 20 mins), when I go to produce the race report it brings up the time as 0.000000
What am I doing wrong?
Here is the code
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <float.h>
typedef struct
{
char fname [15] ;
char sname [35];
int age ;
char category [2];
int number;
float time;
}
competitor_details;
//Global Variables
FILE *compfile;
competitor_details comp;
int choice=0;
//Declare Functions
void menu (void);
void entercompetitordetails(void);
void producecompetitordetails(void);
void enterracetimes(void);
void produceracereport(void);
int main(int argc, char *argv[])
{
menu();
system("PAUSE");
return 0;
}
void menu()
{
while (choice !=9)
{
system("CLS");
printf(" +++++++++++++++++++++++++++++++++++++++++++\n");
printf(" + Competitor details +\n");
printf(" + +\n");
printf(" + [1] Enter competitor details +\n");
printf(" + [2] Produce competitor details +\n");
printf(" + [3] Enter race times +\n");
printf(" + [4] Produce race report +\n");
printf(" + [9] Exit +\n");
printf(" + +\n");
printf(" +++++++++++++++++++++++++++++++++++++++++++\n");
printf(" Enter Choice " );
scanf("%i",&choice);
printf("\n");
switch (choice){
case 1:entercompetitordetails();
break;
case 2:producecompetitordetails();
break;
case 3:enterracetimes();
break;
case 4:produceracereport();
break;
case 9:printf("exit\n");
break;
default : printf("It is one of the undefined values\n");
system("PAUSE");
break;
}
}
