look around this problem when i compile this program
it gives the Floating point formats not linked
but when i run this
<< moderator edit: fixed
it gives no error
i got the explanation of first question as
compiler encounters a reference to the address of a float so this is error
in the second program we are also passing the address of x
thn why not error
is i missing something that is not clear to me
plz explain what is going on in both the program
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);
}it gives the Floating point formats not linked
but when i run this
main()
{
float x;
scanf("%f" , x);
}[code][/code] tags >>it gives no error

The first one is because it doesn't see any floating point operations, so the library is not linked. [edit]http://cboard.cprogramming.com/showt...171#post322171
The second one is not correct.

Whenever you compile C code you should enable warnings. Some compilers will not complain unless you tell them to complain.
What compiler are you using? Is it an ancient version
of BORLAND C++ or TURBO C? You really need to use a modern compiler - there are free ones on the internet starting with gcc.
And in general, don't compile straight C with a C++ compiler even though it seems to work.
