（c语言）利用指向结构的指针先输入数据，后打印数据，为什么会出现打印出来的都是0？

#include

#define MAXFIRST 20
#define MAXLAST 20
#define G_STORE 3
#define A_STRORE 3
#define CSIZE 4
struct name {
char first[MAXFIRST];
char last[MAXLAST];

};

struct student{
struct name s_name;
float grade[G_STORE];
float average;

};

void e_function(struct student * ps[],int count);
void f_function(struct student * ps[],int count);
void g_function(struct student * ps[],int count);

int main(void)
{
int index;
int count=0;
struct student solve[CSIZE];
struct student * psolve[CSIZE];
for(index=0;index<CSIZE;index++)
psolve[index]=&solve[index];

printf("Please enter your first name:\n");
while(counts_name.first)!=NULL&&psolve[count]->s_name.first[0]!='\0')
{
printf("Please enter your last name:\n");
gets(psolve[count]->s_name.last);
printf("Please enter your Chinese grade,Math grade and English grade:\n");
scanf("%.2f %.2f %.2f",&psolve[count]->grade[0],&psolve[count]->grade[1],&psolve[count]->grade[2]);
count++;
while(getchar()!='\n')
continue;
printf("Enter next student's first name:\n");
}

e_function(psolve,count);
f_function(psolve,count);
g_function(psolve,count);

return 0;

}

void e_function(struct student * ps[],int count)
{

int index;
for(index=0;index<count;index++)
    ps[index]->average=(ps[index]->grade[0]+ps[index]->grade[1]+ps[index]->grade[2])/3;

}

void f_function(struct student * ps[],int count)
{
int index;
for(index=0;index {
printf("%s %s ",ps[index]->s_name.first,ps[index]->s_name.last);
printf("Chinese grade,Math grade and English grade:%.2f %.2f %.2f\n",ps[index]->grade[0],ps[index]->grade[1],ps[index]->grade[2]);

}

}

void g_function(struct student * ps[],int count)
{
int index;
for(index=0;index printf("average grade:%.2f\n",ps[index]->average);
}

太长了，没指到正确的变量。或者该变量没赋值

while(counts_name.first!=NULL&&psolve[count]->s_name.first[0]!='\0')
这句话你拷错了吧？counts_name没有定义。

psolve[count]数字在使用前没有初始化。

最好的办法就是单步调试，比较容易分析原因
