@rahul In Standard C you cant define a function inside another function but
you can declare a function inside another function. (so the function can be
defined outside the function).
Eg:-
#include<stdio.h>
void abc()
{
printf("bac");
void abf();
abf();
}
void abf()
{
printf("bas");
getchar();
}
int main()
{
abc();
getchar();
}
coming to Gcc has a language extension that allows nested functions. so
this is entirely compiler dependent.
