#include <stdio.h>
main()
{
int a=8,c;
struct tagMystruct
{
int iNum;
long ILength;
}

AAA.ILength=a;
c=AAA.ILength;
printf("%d",c);
}

运行，错误

你还没有定义那个变量AAA

#include <stdio.h>
main()
{
int a=8,c;
struct tagMystruct
{
int iNum;
long ILength;
};
struct tagMystruct AAA;

AAA.ILength=a;
c=AAA.ILength;
printf("%d",c);
}
