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(…)
Refer this for details and this for more programs that compile in C, but not in C++.
