What is the output of the program
#include<stdio.h>
int main()
{
extern int fun(float);
int a;
a = fun(3.14);
printf("%d\n", a);
return 0;
}
int fun(int aa)
{
return (int)++aa;
}
Answer: Option
Explanation:
2 Errors
1. Type mismatch in redeclaration of fun
2. Type mismatch in parameter aa

In Turbo C it shows the following error:
Error PROGRAM.C 11: Type mismatch in redeclaration of 'fun'
In GCC (Linux) it shows the following errors:
Line 11: error: conflicting types for 'fun'
Line 4: error: previous declaration of 'fun' was here
Error PROGRAM.C 11: Type mismatch in redeclaration of 'fun'
In GCC (Linux) it shows the following errors:
Line 11: error: conflicting types for 'fun'
Line 4: error: previous declaration of 'fun' was here

Please write correct complete program because I want to compile.

A small correction required.
int fun(int aa) --> int fun(floatt aa)
It will display 4 as output.
int fun(int aa) --> int fun(floatt aa)
It will display 4 as output.

Can anyone explain this statement: return (int)++aa in this program ?

@Suman.
(int)++a means that float value of aa is type casted to int. It is called explicit conversion.
