In Java: Using the intermediate variable mechanism:i = i++; Equivalent: temp = i;i = i + 1;i = temp; (i.e. i = i++ = temp) int a = 0,sum; In Java, after using the expression a++, a immediately adds one; For sum = a++ + a+

At the beginning you use this methodint tmp;tmp = A;a = B;b = tmp;Then you know the modular programming, you know this is not good, so you start to use the function.void swap (int *a, int *b); {int tmp;tmp = *a;*a = *b;*b =tmp;} I'm not going to
