Consider the function void doStuff(int parValue, int& parRef) { parValue = 100; cout << parValue in call to doStuff = << parValue << endl; parRef =222; cout << parRef in call to doStuff = << parRef << endl; } and consider the call, which we assume is in a complete and correct program int n1 = 1, n2 =2; doStuff(n1, n2); Select one: a. The call to doStuff results in the assignment n2 = 222; b. The call to doStuff results in the assignment n2 = 100; c. The call to doStuff results in the assignment n1 = 100; d. There is no effect on either of these variables.. e. The call to doStuff results in the assignment n1 = 222;
