NettetOutput. Assume memory address of variable ‘a’ is : 400 (and an integer takes 4 bytes), what will be the output - int a = 7; int *c = &a; c = c + 3; cout << c << endl; Answer: 412 Explanation: c stores address of a (and points to value of a). address that c stores is incremented by 3. since c is of type int, increment in bytes is 3 integer addresses, that … Nettet7. jun. 2014 · 如果a++（++是自增运算符）的值等于b那么k=2，不等于b，k=3。 D=A？B：C; 是三目运算符
