Nettet这是C的一种运算符，逗号表达式。b的值为括号内的第2个值，b=a*4=5*4=20，既然你理解这个，那后边的是一个道理。 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 …
Nettet(a) a - (b++) * (--c); 22. Working a - (b++) * (--c) ⇒ 2 - 3 * 8 [∵ b++ uses current value of b in expression and then increments it, --c decrements c to 8 and then uses this 8 in the expression] ⇒ 2 - 24 ⇒ -22 (b) a * (++b) % c; 8. Working a * (++b) % c ⇒ 2 * 4 % 9 [∵ ++b increments b to 4 then uses it in the expression] ⇒ 8 % 9 Nettet会员中心. vip福利社. vip免费专区. vip专属特权

NettetIn an implementation, when we require to change the initial value of the variable by 1, then go for increment/decrement operators. I.e “++,--“. When we are working with increment/decrement operator the difference b/w existing value and a new value is +1 and -1 only. Depending on the position, these operators are classified into two types.

The answer is option (2). Explanation: Because here c++ is post increment and so it takes value as 4 then it will increment. ++c is pre-increment so it increment first and value 6 is assigned to c, .~ means -6-1=-7 then c= (4-7)=-3. extracttext doesnt workNettetThey are and will be equal if you supply the same initial values of the operands.. In your case, the side effect of the first statement (post increment on a) is affecting the second one.Due to the presence of the post-increment in the first expression, a is incremented to 3 before the next statement is executed.
