Discussion Forum : Structures, Unions, Enums - Point Out Errors (Q.No. 5)
5.
Point out the error in the program?
#include<stdio.h>
int main()
{
struct emp
{
char name[20];
float sal;
};
struct emp e[10];
int i;
for(i=0; i<=9; i++)
scanf("%s %f", e[i].name, &e[i].sal);
return 0;
}
Answer: Option
Explanation:
At run time it will show an error then program will be terminated.
Sample output: Turbo C (Windows)
c:\>myprogram
Sample
12.123

Ya, it doesn't support float, we have to cast inoder to change it to float.

In pc floats are computed through some hardware implementation, i.e.floating point units. When you uses array of structure which contains float values, then this error will come. This error comes because of the format of value -storage of structure.
We can remove this error by explicitly calling the floating point format linker.
Solution is- add following code in your source file, don't call it, it automatically get call when error arises.
static void forcefloat(float *p)
{
float f = *p;
forcefloat(&f);
}

Here no comma seperating %s ND % f.
So floating format is not linked.

void linkfloat(float *p)
{
float a=0,*b;
b=&a;
a=*b;
}
This code causes emulatore to be linked and suppress the warning-variable not found.
{
float a=0,*b;
b=&a;
a=*b;
}

The pgm will work 100% correctly. There is no prob of linker.

Did it in gcc? float value is changed?
Input-vector

Output- vector

&e[i].sal will return an address which is an int and we are using %f in printf to print this is the reason for having floating point format not linked error.

I agree with you Sanjeev. But in the question scanf is used.

Kindly wish to all. Please tell me why it is linked error?
