A C/C++ Function Call Puzzle
Consider the following program. Predict the output of it when compiled with C and C++ compilers.
C
#include<stdio.h> void func() { /* definition */ } int main() { func(); func(2); } |
C++
#include <iostream> using namespace std; void func() { /* definition */ } int main() { func(); func(2); return 0; } |
The above program compiles fine in C, but doesn’t compile in C++.
In C++, func() is equivalent to func(void)
In C, func() is equivalent to func(…)
