程序改错。以下程序用于打印输出结构体数组的所有元素。
struct s
{
char name[10];
int age;
}
main()
{
struct s a[3] = {”John”,19,”Paul”,17,”Marry”,18};
int *p;

for(p = a; p < 3; p++)
{
    printf("%s,%d\n", p->name, p->age );
}

}

答案：

#include<stdio.h>
struct s
{
    
    
    char name[10];
    int age;
};
int main()
{
    
    
    struct s a[3] = {
    
    
               {
    
    "John",19},
               {
    
    "Paul",17},
               {
    
    "Marry",18}
               };
    struct s *p = a;
    for(p = a; p < &a[3]; p++)
    {
    
    
        printf("%s,%d\n", (*p).name, (*p).age );
    }
}
