    Default Help with prefix and postfix(increment&decrement)

    I know that when used alone both prefix postfix work the same way but in expressions it behaves differently when combined.

     
    int a=1,b=3,c=4,d=0;
    d=a-(b++)*(c++)

    please explain its working

    Default Re: Help with prefix and postfix(increment&decrement)

    The results of a postfix operation are the original value, where the prefix results are that of the new value.

    int a = 3;
    int b = a++; // increment a after setting b=a
    int c = ++a; // increment a then set c=a
