Question

我必须使用define创建结构数组。请建议我怎么做。

file1.c have data
{
    "string1",
     13         
}

file2.c have data              
{
    "string2",
    14         
}

需要将此数据传递给一个公共定义，以便它可以填充如下数据：

struct test data[]=
{
    {"string1", 13}, 
    {"string2", 14}
}

让我在这里详细说明：

file1.c
ADD_DATA_IN_STRUCT(....) ---> pass data {"string1", 13}

file2.c
ADD_DATA_IN_STRUCT(....) ---> pass data {"string1", 14}

main.h
#define ADD_DATA_IN_STRUCT(....)  ---> should expand to
struct test data[]=
{
    {"string1", 13}, 
    {"string2", 14}
}

希望它有所帮助，我遗漏了细节。

// 1. define the test struct
define struct test {
    char *string;
    int number;
};

// 2. define the data array
struct test data[2];

// 3. read file, assign value to corresponding fields in data array
// you may want to dynamically allocated memory for `string` using `malloc`
// or if the string has a maximum size, define it using `char string[MAX_SIZE]` instead

使用define填充结构数组
