You have only allowed enough room to read in a string of length 1 into ch.

Hi guys,
I started my programming class at college today and the first task is to create a program to convert kilograms to stone and pounds and pounds and stones to kilos. Im working on the first one now and so far I have this

include

int main ()
{
float a;
printf ("Kilograms to Stones and Pounds Program \n Enter the amount in Kilograms");
scanf ("%f",a);
a = a / 2.2;
printf ("%f",a);
getchar();
getchar();
return 0;
}

However when I run it, and type a number in it crashes. The debug on Spoj C++ says, An Access Violation (Segmentation Fault) raised in your program. Any ideas?

scanf ("%f",a);

That is not how you use scanf. Have a look at the documentation for scanf.
