Question

What is the output of the following program? \#include void f1(); void f2(int n ); int main() \{ using namespace std; f1(); f2(4); cout ≪ "End of program. In"; return 0 ; \} void f10) \{ using namespace std; cout ≪ "Helloln"; \} void f2 (int n ) \{ using namespace std; if (n<5) return; f1(); cout « "Goodbye \ "; \} \{ using namespace std; if (n<5) return; f1(); cout ≪< "Goodbyeln"; \} Hello End of program. Syntax Error Hello Hello Goodbye End of program. Hello Goodbye Hello End of program.

Answer 1

The output of the corrected C++ program would be 'Hello' followed by 'End of program.' on a new line, as the condition in f2(int n) causes it to return before printing 'Goodbye' since the argument 4 is less than 5.

Step-by-step explanation:

The provided code seems to be a C++ program with certain errors that need correction for proper interpretation. There are multiple syntax errors such as incorrect function definition for f1() and incorrect use of stream insertion operator ≪ which should be <<.

Assuming corrections are made, the function f1() outputs 'Hello' followed by a new line when called. The function f2() only calls f1() then returns immediately without printing 'Goodbye' if the argument n is less than 5.

In the main function, f1() is called first, printing 'Hello'. Then f2(4) is called but since 4 is less than 5, it returns immediately without further output. Finally, 'End of program.' is printed by the main function. Therefore, the correct output, after fixing the errors, should be:

Hello\\End of program.\\
