Question

当我尝试打印字符串＆＃34; descpt＆＃34;时出现问题。请有人帮助我。这是我的代码：

struct Article {
    int a;
    int b;
    const char *descpt[20];
};

void Print(Article * data) {
    printf("The article number is %d\n", data->a);
    printf("The quantity is %d\n", data->b);
    printf("The article number is %s\n", data->descpt[20]);
}

int main() {
    Article data;
    data.a = 10;
    data.b = 20;
    data.descpt[20] = "Articles";
    Print(&data);
    return 0;
}

Answer 1

#include<stdio.h>
#include<string.h>
struct Article {
    int a;
    int b;
    char descpt[20];
};

void Print(Article * data) {
    printf("The article number is %d\n", data->a);
    printf("The quantity is %d\n", data->b);
    printf("The article number is %s\n", data->descpt);
}
int main()
{
    Article data;
    data.a = 10;
    data.b = 20;
    strncpy_s(data.descpt, "Articles", strlen("Articles"));
    Print(&data);
    return 0;

}

也许你想要这样的东西？

struct Article {
    int a;
    int b;
    const char descpt[20]; /* array of max 19chars+terminator\0 */
};

void Print(Article * data) {
    printf("The article number is %d\n", data->a);
    printf("The quantity is %d\n", data->b);
    printf("The article number is %s\n", data->descpt);
}
int main()
{
    Article data;
    data.a = 10;
    data.b = 20;
    strcpy(data.descpt,"Articles");
    Print(&data);
    return 0;
}

对于strcpy()，您必须#include <string.h>
