The specific package library that implements the OutputList disable feature may vary depending on the programming platform being used. In general, it is likely to be part of a larger debugging or testing library.int main() { int a = 5; int b = 10; int c = a + b; #if !defined(DISABLE_OUTPUT) std::cout << "The value of c is: " << c << std::endl; #endif return 0; }
