foo is just a common arbitrary name for something, often a function. It is commonly used in combination with another name called bar:
I suppose you could use somehting like jumpin and jehosephat instead of foo and bar, but foo-bar has some funny historical implications, sorta like "Kilroy was here", so it has just stuck.Code:#include <iostream> using namespace std; void foo() { cout << "Hello" ; } void bar() { cout << " World!" << endl; } int main() { foo(); bar(); return 0; }
