why is the output wrong??

sooo , shouldn't this program give me the multiple of a and b? what did i do wrong here? #include <iostream> using namespace std; int main() { int a,b,c,i =0; cout << "insert an integer : "; cin >> a; cout << endl << "insert another : "; cin >> b; for (i=0; i >= b; i = i+1) { c = a+c; } cout << a << "x" << b << "=" << c; return 0; }

The condition part of the for loop is false from the beginning. You would only need to change >= to <.

endl ( in line 8th) must be end of statemant and the conditions in your for loop is wrong ( line 10th)
