Nettet23. feb. 2011 · a++ is postfix increment and ++a is prefix increment. They do not differ when used in a standalone statement, however their evaluation result differs: a++ returns the value of a before incrementing, while ++a after. I.e. int a = 1; int b = a++; // result: b == 1, a == 2 int c = ++a; // result: c == 3, a == 3 Share Improve this answer Follow Nettet#include int main() { int a = 5, b = 0; printf("\n%d", a && b); printf("\n%d", a b); printf("\n%d", !a); printf("\n%d", !b); return 0; } Output Since a is non-zero but b is zero, so AND between them will be false (or 0). As only one of them is true (or non-zero). Nettet23. aug. 2024 · Explanation: ++a +b = 6 + Garbage floating point number = Garbage floating point number // From the rule of automatic type conversion. Hence sizeof operator will return 4 because size of float data type in c is 4 byte. Value of any variable doesn’t modify inside sizeof operator. Hence value of variable a will remain 5. rv wheelchair

Nettet5. feb. 2011 · The second UB is related to the post-incrementation and the potentially trivial line a = a++. As it occurs, there are also two possibilities here (I'll demonstrate them using int a = 5; a = a++; as an example). Terminology: a_mem - a still in memory (e.g. as a local variable somewhere on the stack) Nettet后置a++相当于做了三件事情： 1. tmp = a; 2. ++a 3. return tmp; 事实上，如果这里a是一个对象，而非一个基本类型数据的话，我们重载其后置自增运算符就分成上述三个步骤（参考《C++Primer 第五版》p503 “区分前置和后置运算符”小节） 再简单的说说什么是右值吧，所谓右值，可以理解为是即将结束生命周期的对象。 在这里， (a++)返回的是a在+1 …
