True or False You may skip members in a structure's initialization list.

Structures are user-defined data types in C and C++ that allow grouping variables of different data types under a single name. We can define a structure using the "struct" keyword followed by the structure name, and its members within the curly braces. For example: ```c struct Student { int roll_no; char name[20]; float marks; }; ``` The above structure consists of an integer roll_no, a character array name, and a float marks.

In C and C++, structures can be initialized during declaration or using an assignment statement. For example: ```c struct Student s1 = {1, "John", 85.5}; ``` or ```c struct Student s2; s2.roll_no = 2; strcpy(s2.name, "Alice"); s2.marks = 89.0; ```

If we do not initialize a structure member in the initialization list, the member will have an undefined value when using automatic storage duration. For structures with a static or thread storage duration, the members will be initialized to 0 when not explicitly initialized. It is possible to skip members in a structure's initialization list in C99 (and later standards) and C++11 (and later standards) using designated initializers. Designated initializers allow specifying the members we want to initialize, and the value we want to initialize them with, using the member's name followed by the assignment operator and the value within braces. For example, we can initialize a structure and skip the name: ```c struct Student s3 = {.roll_no = 3, .marks = 90.0}; ``` In this case, the `name` member's value will be uninitialized if the structure has an automatic storage duration, and will be initialized to an empty string (all bytes set to 0) if it has a static or thread storage duration. So, the statement is True - You may skip members in a structure's initialization list in C99 onwards and C++11 onwards. However, it is important to be careful about uninitialized values in structures with automatic storage duration.
