This article mainly introduces the C language structure in the char array how to assign, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor with you to understand.

Foreground hint

Define a structure in which there are two variables, one of which is an array of type char, so how do you insert data into this array and print it?

Typedef struct SequenceList {/ / element of the array char element [20]; / / length of the array int length;}

Define a structure in which there are two variables, one of which is an array pointer of type char, so how do you insert data into this array and print it?

/ / define the sequence table structure typedef struct SequenceList {char * elment; int length;}

The steps to deal with the structure here

Structure initialization

Structure in vivo data assignment

Structure output data in vivo

In accordance with the above principles, first operate on the first type

I. processing of char array types 1. Structure initialization SequenceList L; L.element = (char*) malloc (sizeof (char) * 10); L.length = 102. Structure in vivo data assignment (simple method) L.elment [0] = 1; L.elment [1] = 2; L.elment [2] = 3; L.elment [3] = 4; L.elment [4] = 5

For cycle

For (int I = 0; I

< 10; i++) { L.elment[i] = i+1; } 3.结构体内输出数据 for (int i = 0; i < 10; i++) { //不会打印空值 if (L.elment[i]>

0) {printf ("element [% d] =% d\ n", I, L.elment [I]);} di. Char array pointer type processing 1. Structure initialization / / structure initialization MyList L; L.length = LENGTH; L.elment = (char*) malloc (L.length * sizeof (char)) 2. Structure body data assignment / / structure body assignment for (int I = 0; I

< LENGTH; i++) { *(L.elment + i) = 'A' + i; }3.结构体内输出数据 //打印结构体中的值 for (int i = 0; i < LENGTH; i++) { if (*(L.elment + i) >

0) {printf ("elment [% d] =% c\ n", I, * (L.elment + I);}} 3. All code 1. Char array / / 010. Sequence table _ 004.cpp: this file contains the "main" function. Program execution will begin and end here. / / # include # define MAXSIZE 10 typedef struct SequenceList {/ / element of the array char element [MAXSIZE]; / / length of the array int length;}; int main () {/ / 1. Initialize the structure SequenceList* L; L = (SequenceList*) malloc (sizeof (char) * MAXSIZE); L-> length = MAXSIZE; / / 2. For (int I = 0; I) is stored in the structure.

< MAXSIZE; i++) { L->

Element [I] ='a'+ I;} / / 3. Print the value for (int I = 0; I) inside the structure

< MAXSIZE; i++) { if (*(L->

Element + I) > 0) {printf ("elment [% d] =% c\ n", I, * (L-> element + I));}

2. Char array pointer / / 011. Sequence table _ 005.cpp: this file contains the "main" function. Program execution will begin and end here. / / # include # define MAXSIZE 10typedef struct SequenceList {/ / element of the array char * element; / / the length of the array int length;}; int main () {/ / 1. Structure initialization SequenceList L; L.length = MAXSIZE; L.element = (char*) malloc (L.length * sizeof (MAXSIZE)); / / 2. Assign for (int I = 0; I) in the body of the structure

< MAXSIZE; i++) { *(L.element + i) = 'a' + i; } // 3.打印结构体中的值 for (int i = 0; i < MAXSIZE; i++) { if (*(L.element + i) >

0) {printf ("elment [% d] =% c\ n", I, * (L.element + I));}

Thank you for reading this article carefully. I hope the article "how to assign char arrays in C language structure" shared by the editor will be helpful to you. At the same time, I also hope you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
