Nettet25. nov. 2024 · Explanation: Usually, the compilers read parameters of printf () from right to left. So, ‘a++’ will be executed first as it is the last parameter of the first printf () statement. It will print 10. Although, now the value has been increased by 1, so the second last argument, i.e., will print 11. Nettet24. mai 2024 · int a = 15, b; b = (a++) + (a++); a = (b++) + (b++); printf("a=%d b=%d", a, b); return (0); } Options: 1. a=63 b=33 2. a=33 b=63 3. a=66 b=33 4. a=33 b=33 The answer is option (1). Explanation: Here, a = 15 and b = (a++)+ (a++) i.e. b = 15+16 = 31 and a =3 2. Now a = (b++) + (b++) = 31 + 32 = 63 and b = 33.

Nettet先说结论: 因为a++返回的是右值 (rvalue),而我们不能对一个右值进行自增操作。 所以++ (a++)会报错。 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 …
