typedef 字符串

Here, we have to define an alias for a character array with a given number of maximum characters length to read strings?

在这里，我们必须为具有给定最大字符长度数的字符数组定义别名，以读取字符串 ？

In the below-given program, we have defined two alias (typedefs) for character array and unsigned char:

在下面给出的程序中，我们为字符数组和无符号字符定义了两个别名(typedef)：

    typedef char CHRArray[MAXLEN];
typedef unsigned char BYTE;

MAXLEN is also defined with 50 by using define statement #define MAXLEN 50.

MAXLEN还与50通过定义语句的#define MAXLEN 50界定。

Declaring variables:

声明变量：

    CHRArray name;
CHRArray city;
BYTE age;

Explanation:

说明：

CHRArray name will be considered as char name[50], CHRArray city will be considered as char city[50] and BYTE age will be considered as unsigned char age.

CHRArray名称将被视为char name [50] ， CHRArray city将被视为char city [50] ， BYTE age将被视为unsigned char age 。

Note: unsigned char is able to store the value between 0 to 255 (i.e. one BYTE value).

注意： unsigned char能够存储0到255之间的值(即一个BYTE值)。

Program:

程序：

#include <stdio.h>
#include <string.h>
#define MAXLEN 50
typedef char CHRArray[MAXLEN];
typedef unsigned char BYTE;
int main()
{
CHRArray name;
CHRArray city;
BYTE age;
//assign values
strcpy(name, "Amit Shukla");
strcpy(city, "Gwalior, MP, India");
age = 21;
//print values
printf("Name: %s\n", name);
printf("city: %s\n", city);
printf("Age : %u\n", age);
return 0;
}

Output

输出量

Name: Amit Shukla
city: Gwalior, MP, India
Age : 21
