In this article, the editor introduces in detail "the method of initializing the body array of c language structure". The content is detailed, the steps are clear, and the details are handled properly. I hope that this article "the method of initializing the body array of c language structure" can help you solve your doubts. Let's follow the editor's train of thought to learn new knowledge.

Initialization of structure array

The initialization of the structure array is the same as that of the basic data type array, and all elements can be initialized.

Transformation, initialization of some elements, etc.

Struct student

{

Int id

Char name [20]

Char gender

Double score

}

For the struct type student, here are several examples of struct array initialization.

1. Initialization of all elements of the array

The common form of all element initialization is branch initialization, where the initial values of each member of each struct type element are placed.

In a separate curly braces, this approach is more intuitive and clear. For example:

Struct student stu [2] = {{101l, "zhang", 'Lee, 90}}

When all element branches are initialized, you can omit the length of the array, for example:

Struct student stu [] = {{101l, "zhang", 'Lee, 90}}

When all elements are initialized, you can also omit the curly braces that distinguish each array element internally, and the above two initializations can also be

In the form of the following

Struct student stu [2] = {101,10, "zhang", 'Lee, 95,102, Lee, 90}

Struct student stu [] = {101, "zhang", 'Lee, 95,102, Lee, 90}

two。 Array partial element initialization

When initializing some elements of a structured array, the array length in the array definition cannot be omitted. You can initialize several elements of an array, with or without branches.

The following is an example of initializing the first two elements of an array in a branch manner

Struct student stu [10] = {{101l, "zhang", 'Lee, 90}}

The following is an example of initializing the first two elements of an array in an unbranched manner:

Struct student stu [10] = {101,102, "zhang", "Lee", "Lee" 90}
