Hi myself vandana. I wanna know how can we use float variables with in C structures. Can anyone help me.

Hi Vandana,
The question seems to be generic. It would be useful to suggest when it is more specific.

have a look at this tutorial on Data Structures

Hi Vandana,

hello ji,
Actually i wanna write a program who can accept data of 10 players and sort them and display result team wise. when i started i write code to scan details.
but it gives message at runtime while entering first floating value that floating point formats not linked abnormal program termination.

i m sending my code of program

#include<stdio.h>
#include<conio.h>
#include<string.h>
struct player_detail
{
    char player_name[15];
    char team_name[15];
    float batting_avg;
}players[10];
void main()
{
    int i,x;
    for(i=0;i<3;i++)
    {
        printf("\nEnter Player Name : ");
        gets(players[i].player_name);
        printf("\nEnter Team : ");
        gets(players[i].team_name);
        printf("\nEnter Batting Average : ");
        scanf("%f",&players[i].batting_avg);
    }
}

this is a problem with Visual C where it does not load floating point support if it does not think it necessary, see
http://msdn2.microsoft.com/en-us/library/k1x26e0x.aspx

try putting a dummy floating point assignment in the program to force loading of the support, e.g.

int  main()
{
    int i,x;
    float z=10.0f;

Hi,
i m using C++ compiler of versoin 3.0. & this is also giving the same Problem.
Will u please tell me how i can use float in structures while using same compiler.

did you try defining a float to force loading of the libraries? e.g.

int  main()
{
    int i,x;
    float z=10.0f;

is it Visual C++ V3.0 or another compiler?

it is turbo c++.

[horace1]

it is turbo c++.

it appears in Turbo C V3.0 you have to force loading of the floating point conversions, see
http://www.vmlinux.org/~jakov/community.borland.com/15204.html

it recommends that you include the following function in your code - you don't need to to call it

          static void force_fpf()
          {
              float x, *y; /* Just declares two variables */
              y = &x;      /* Forces linkage of FP formats */
              x = *y;      /* Suppress warning message about x */
          }

Thx ur advice works. thx again for sending this article.

vandanasridhar hi
I have the problem to.it was simple just use a dumi float variable out of the structure then assign the value and use the variable;

struct dum{

int a;
float f;
----------
---------
};

int dum_f = f ;

@vandanasridhar
try including <float.h> header file

Hi Vandana
Don't worry
There is simple solution for ur problem when getting the error
"scanf : floating point formats not linked
Abnormal program termination"



just add the two given lines in ur program

extern void _floatconvert();
#pragma extref _floatconvert


and enjoy it



one example code is given

#include<stdio.h>
 
 
extern void _floatconvert();
#pragma extref _floatconvert
 
 
 
struct stud
{     char name[50];
    float m1, m2, m3, total;
}s[10];
void main()
{
    int n,i;
    clrscr();
    printf("How many students? \t");
    scanf("%d",&n);
    for(i=0;i<n;i++)
    {
        printf("\nGive name of student%d:\t",i+1);
        scanf("%s",s[i].name);
        printf("\nGive 3  marks of %s\t",s[i].name);
        scanf("%f%f%f",&s[i].m1,&s[i].m2,&s[i].m3);
        s[i].total = s[i].m1 + s[i].m2 + s[i].m3;
    }
    printf("\nNAME\t\tMARK1\tMARK2\tMARK3\tTOTAL");
    for(i=0;i<n;i++)
    {
        printf("\n%s\t\t%0.2f\t%0.2f\t%0.2f\t%0.2f",s[i].name, s[i].m1, s[i].m2, s[i].m3, s[i].total);
    }
}
