Key Difference – Structure vsUnionin C An arrayis a data structured supported byC language.An array can be used to store data elements of the same type. If there is a statement as int marks [10]; then marks are an array that can store ten marks and all of them are integers. Sometim...

今天在编译一个C语言程序时,对于结构体变量,报出错误 Error: request for member ‘xxx’ in something not a structure or union。 经过调试发现是 . 与 -> 搞错了。 如果它是地址,就在它后边用 ->,如果它不是地址,就在它后边就用 . 代码举例简略如下: #include <stdio.h> #include <string.h> typed...
因为结构体student里面的num是个数组，而不是一个普通的变量。当你想访问num这个数组的时候，你应该这么样acm[i].num[1]指定想要访问的数据元素。根据提示，直接把两处的acm.num改成acm->num不就行啦。我来做个任务，路过

对于结构体变量,报错如下:Char 20: error: request for member ‘length’ in something not a structure or union [solution.c] 意思为:在非结构体中请求成员“长度”。 解决思路: 结构名和变量名没有关系。 参数nums是一个指针(int nums[ ]在函数参数中与int *nums具有相同的含义)并且它没有成员。
c: In function ‘give_bob_a_job’: bob.c:18:6: error: request for member ‘job’ in something not a structure or union So we receive the error error: request for member ‘job’ in something not a structure or union. We run through a mental checklist: ...
Note:Alignment of data types mandated by the processor architecture, not by language. A final thought about structure padding in C: When you create an object ofstructureorunionthe compiler may insert some extra bytes between the members of the structure or union for the alignment. These extra ...
