what have i to do, if i want that the program always writes for example : 0+1 1+2 3+3 6+4 10+5 15+6 ... because now it just writes 1 3 6 10 15 ... and maybe if it works, can i make then 0+1=1 1+2=3 3+3=6 6+4=10 #include <iostream> using namespace std; int main(){ int i; int sum = 0; for (i = 1; i <= 100; i++){ sum = sum+i; cout<<sum<<endl; } cout<<sum; return 0; }

#include <iostream> using namespace std; class A{ public: void f1(); }; class B : public A{ public: virtual void f1(); } int main() { A * obj = new B; obj.f1(); } Ques: can we write virtual before an overridden function from the base class?? if yes which f1() should it call base class f1() or derived class f1()???

WY I get a rundum number from memory when I run this code #include <iostream> using namespace std; int main () { int array [5]; for (int x = 0; x < 5; x++) { array [x] = 42; cout << x << ': ' << array [x] << endl; } return 0; } if I replace ': ' with ": " every thing works well.
