C ++：获得两个月/年之间的范围

Question

In class, we're doing an assignment to get the range between two dates using months and years as input.

My process code is as follows:

    int totalMonths1 = (year * MONTHS_IN_YEAR) + month;
    int totalMonths2 = (year2 * MONTHS_IN_YEAR) + month2;
    int range;

    if(totalMonths1 > totalMonths2)
    {
        range = totalMonths1 - totalMonths2;
    }

    if(totalMonths1 < totalMonths2)
    {
        range = totalMonths2 - totalMonths1;
    }

With const int MONTHS_IN_YEAR = 12.

This tells me the difference between the two dates, but not the range. If I add 1 to the result, it's the correct range according to my professor's example program, but I'd like to know if there's a better way to get the range instead of doing "difference + 1".

Answer 1

No. It doesnt get any simpler/better than a - b + 1 . Unfortunately, anything else is over-complicating the solution and unnecessary.
