Question

我在Linux上写了一个C程序。当我编译程序时，没有错误发生，但是当我运行它时，我收到了一些错误。我的节目是，

#include <stdio.h>

typedef struct a{
 char *name;
 int id;
 char *department;
 int num;
} ab;

int main()
{
 ab array[2]={{"Saud",137,"Electronics",500},{"Ebad",111,"Telecom",570}};
 printf("First student data:\n%s\t%d\t%s\t%d",array[0].name,array[0].id,
     array[0].department,array[0].num);

 //ab swap(&array[]);
}

错误是：

要编译，你需要写这个：

gcc -o newproject newproject.c

这将创建一个名为newproject的文件，您可以通过编写此文件来运行该文件：

./newproject

将gcc ./newproject写入运行您的程序没有任何意义。
