Once you have defined a union, you can create variables of that type. For example, the following code creates two variables of type Data:union Data data1, data2; Continue Reading...Next > Strings in C Related Topics C Structures (structs) Strings in C...
in C? #include <stdio.h> #include <stddef.h> #include <assert.h> // Example `union` in C union int_or_char { int i; char c; }; // Compare it to this to the similar `struct` struct int_and_char { int i; char c; }; int main(void) { // The struct makes room for bo...
In this section, we will see the example of the union in c, in the example we will see the proper declaration of union in c with the initialization of union variables and the proper way of accessing union variables in the code. Code Implementation: C #include <stdio.h> #include <string...
unionexample{struct{shortintx;shortinty; }in;shortinta;shortintb; }e; e.in.x =2; e.in.y =3;int*t = (int*) (&e);printf("t = %x\n", *t); 输出t = 30002,即表明e.in.x存放在低位short int,e.in.y存放在高位short int 如将定义修改为 unionexample{struct{shortinty;shortintx;...
C语言中enum枚举类型 C语言中enum枚举类型 枚举类型是多个离散整形数据的集合体,编译器把枚举类型中的数据当做整形常量处理,将数据存储在常量区域。枚举类型变量定义有三种方式:1、声明枚举类型然后再定义枚举类型变量;2、声明枚举类型同时定义枚举类型变量;3、定义枚举类型变量。具体使用方法如下图所示: 图 枚举类型...

The following example is a modified version of the previous example. In this version, the line that assigns the value 3.1416 to Values.dValue is commented out. This causes the code to try to print the value of an inactive member of the union (that is, a member that never receives an ...
The example depicted in Figure 3 illustrates the little endian and big endian storage of the sequence 0x01020304. Figure 3.Image courtesy of IAR. Let’s use the following code to experiment with the union of the previous section: #include <stdio.h> ...
