2下列程序的输出结果是( )。 #include <stdio.h> struct abc { int a, b, c, s;}; main() { struct abc s[2]={{1,2,3},{4,5,6}}; int t; t=s[0].a+s[1].b; printf("%d\n",t); } A.5B.6C.7D.8 反馈 收藏
printf("sizeof(struct A)=%d, sizeof(struct B)=%d\n",sizeof(structA),sizeof(structB));return1; } 结果: 分析: structA{chara;//1intb;//空3 + 4 = 7 (规则1)shortc;//2+空2=4 (规则2)};structB{chara;//1shortb;//空1 + 2 = 3 (规则1)intc;//4}; 上面是问题的简化版,...

Whena classinstance constructor has no constructor initializer, or it has a constructor initializer of the formbase(...), that constructor implicitly performs the initializations specified by thevariable_initializers of the instance fields declared in its class. This corresponds to a sequ...
a generic class typeS, using templates or anything else standard, even ifSis a complete type (in which case, the compiler obviously knows its members). If we're lucky we might get something like this in C++20, but right now there's no way to actually implement the fully genericfor_each...
C 正确答案:C 解析:将题目中的定义语句去掉前面的typedef和后面的NEW(分号保留),就是一条完整的结构体定义语句,其中struct是说明符,ST是结构体名,大括号里面的是结构体成员的定义。此时要声明该结构体变量时需要使用struct加结构体名一起来声明,struet ST一起构成一个结构体类型,就好像字符类型char.若只去掉前...
