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...
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;...
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...

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 ...
Example C = union([5 5 3],[1 2 5],'sorted') C = 1 2 3 5 'stable' The values (or rows) inCreturn in the same order as they appear inA, thenB. Example C = union([5 5 3],[1 2 5],'stable') C = 5 3 1 2
Sheet2 is activated and the Union function is used to select B4:B8 and C4:C8. The RGB color is changed using the Interior.Color command (here, Cyan 150, 250, 230). Run the code. This is the output. Read More: How to Do Union of Two Columns in Excel Example 3 – Displaying ...

In the previous example, any code that accesses the union needs to know which member holds the data. The most common solution to this problem is called a discriminated union. It encloses the union in a struct, and includes an enum member that indicates the member type currently stored in ...
