how to make link betwenn flaoting point to printf statement?

[venkatesh]

hai to everybodey,
suppose i am using float variable in
structure,when i am manupulating them it will not shows the linkage
error? but when i am using scanf to read particular variable it shows
run time error?
how to make explicitly link betwen floating point
library and to printf statement?



thanks in advance

you'd better post your code here,so we can found what wrong with that.

my code is
struct add
{
float x;
}y;
main()
{
scanf("%f",&y.x);

This means that your compiler left
the floating point package out, and at runtime it can't do
a floating point scan.

Upu should either:
1) Instruct your compiler to link the floating point package.
2) Get a better compiler.

my code is
struct add
{
float x;
}y;
main()
{
scanf("%f",&y.x);

See the FAQ mentioned below. It covers the exact situation.

This is question 14.13 in the C FAQ.

please tell how to make exiplicit includetion for flaoting point

please tell how to make exiplicit includetion for flaoting point

for that you'll need to look up your platform documentation - the only
advice given in the faq, IIRC, is for unix platforms, which do not
require the math library for %f formats.
