Nettet12. okt. 2024 · Let us understand the execution line by line. Initial values of a and b are 1. // Since a is 1, the expression --b // is not executed because // of the short-circuit property // of logical or operator // So c becomes 1, a and b remain 1 int c = a --b; // The post decrement operator -- // returns the old value in current expression // and then updates … Nettetint b = 10; int c; c = a + b; Console.WriteLine("Line 1 - c 的值是 {0}", c); c = a - b; Console.WriteLine("Line 2 - c 的值是 {0}", c); c = a * b; Console.WriteLine("Line 3 - c 的值是 {0}", c); c = a / b; Console.WriteLine("Line 4 - c 的值是 {0}", c); c = a % b; Console.WriteLine("Line 5 - c 的值是 {0}", c); // ++a 先进行自增运算再赋值 c = ++ a;

Nettet23. mai 2016 · int * (*a) (int) ;a是一个指针,指向输入参数是int,返回值是int*(整型指针了)的函数。 另外函数指针是这么调用的:假设函数指针p,指向一个输入参数为int, … Nettet5. mar. 2024 · First, a is assigned as 10. ⇒ a = 10. b is assigned the value 20. ⇒ b = 20. c isn't assigned any value till now. c = a this signifies that c is assigned value 10 as a = 10. ⇒ c = 10. Now, b = c, earlier b was assigned value as 20 but since, b =c this means the value of b would be 10 as c = 10. ⇒ b = 10 Nettetpublic class Test { public static void main(String[] args){ int a , b; a = 10; // 如果 a 等于 1 成立,则设置 b 为 20,否则为 30 b = (a == 1) ? 20 : 30; System.out.println( "Value of b is : " + b ); // 如果 a 等于 10 成立,则设置 b 为 20,否则为 30 b = (a == 10) ? 20 : 30; System.out.println( "Value of b is : " + b ); } } 以上实例编译运行结果如下: Value of b is … horing lih industrial
