    void calc(int &a, int b) { cout << a << "\t" << b << endl; a = b++; b = a++; cout << a << "\t" << b << endl; } void main() { int x = 5; calc(x++, ++x); cout << x << endl; } that one?

    so to begin with x = 5 when you call calc(x++, ++x) x will be incremented before the function and after x = 6 calc effectively gets called with a = 6 and b = 6 this is before a is a reference of x so the first output would be 6 6

    almost a = b++; // b is 6 so now a and x are 6, remember this is a post increment b = a++; // a is 6 so now b is 6 and a and x are 7 So the output should be 7 6

    ok i see now, with 1f you have x = 725 y = 245 a is between 4 and 6 (i'm assuming the random function returns [0, n) ) b is between 2 and 3 do you think you could do this one now?

    for 1f the answer would be a) and 1e the first for loop is working out the length of the string. c strings are terminated by a '\0' the second loop is looping from 0 to the middle of the word and if statement is looking for capital A's and E's since there are no A's or E's in the first half this wont ever happen and in the else it's swapping characters, eg first with last, second with second last etc so the result would be a word that is reversed if it doesn't have any A's or E's in the first half of the word PreboardExam would become maxEbraoberP
