Answer 2

string a; //you forgot a semicolon

cin >> c; //no '}'

if (a=="add" ) {

//= means assignment in C++. You are trying to give a the value add. == is the equality comparison. Moreover a == add checks to see wether the variable a has the same value as the variable add. "add", with quotation marks, refers to the value itself.

if (a=="multiply") {
