Question about declaring Floating Point Variable in a Structure

[Nasir Khan]

Dear Sir,

I am a newbie in C. I am trying to run the following code.
main()
{
struct emp
{
float sal;
};
struct emp empl;
scanf("%f",&empl.sal);
printf("%f",empl.sal);
}


This program compiles fine but at run time I get error. I am using
Borland C on windows.

IF any one has got similar problem and knows a fix, please help me.

Kind Regards,
Nasir Khan

I am a newbie in C. I am trying to run the following code.

main()
{
struct emp
{
float sal;
};
struct emp empl;
scanf("%f",&empl.sal);
printf("%f",empl.sal);
}

I have no problems with this code in Turbo C 2.0
You can try to write in such way:

main()
{
struct emp
{
float sal;
} empl; /* another way of declaration*/
scanf("%f",&empl.sal);
printf("%f",empl.sal);
return 0;
}

You have a virus in your left thumb.

*WHAT* is the error? Describe it. Presenting the exact wording
wouldn't hurt. How do you know it is an error?

If you get an error when you try to use your car, there's a large
difference if the key won't turn vs. you get a letter in the mail
from the finance company.

main()
{
struct emp
{
float sal;
};
struct emp empl;
scanf("%f",&empl.sal);
printf("%f",empl.sal);
}

First, note the differences between your code and

#include <stdio.h>
#include <stdlib.h>

int main( void )
{
struct emp
{
float sal;
};
struct emp empl;
scanf("%f",&empl.sal);
printf("%f\n",empl.sal);
return( EXIT_SUCCESS );
}

1) You included no header files. All bets are immediately off.
2) main() returns int, although C89 will let you get away without
saying so.
3) Omitting the trailing newline may cause problems depending on your
implementation.

This program compiles fine but at run time I get error. I am using
Borland C on windows.

What error? Neither bcc32 5.4 nor gcc 2.95.3 complains at compile
time or run time; bcc32 5.4 even compiles your original broken code
and runs it cleanly. You'll have to be more specific about what
you're doing and what's going wrong; and before you do, read the
following links:

What error do you get?

Actually, there are numerous errors in your code. Try this:

#include <stdio.h> /* added header */

int main(void) /* added return type */
{
struct emp
{
float sal;
} empl; /* simplified */
printf("Enter sal: "); /* added prompt */
fflush(stdout); /* added */
scanf("%f", &empl.sal);
printf("%f\n", empl.sal); /* added newline */
return 0; /* added */
}
