Discussion Forum : Functions - Point Out Errors (Q.No. 3)
3.
Point out the error in the program
#include<stdio.h>
int main()
{
int a=10;
void f();
a = f();
printf("%d\n", a);
return 0;
}
void f()
{
printf("Hi");
}
Answer: Option
Explanation:
The function void f() is not visible to the compiler while going through main() function. So we have to declare this prototype void f(); before to main() function. This kind of error will not occur in modern compilers.

f() is a void type function which does not return value so assignment is not allowed.

Wrong because the function f () is not returning anything?

It should be before your calling function.
