一道c语言练习题,求高手帮忙解答

[偷偷闲浮生]

最近想入门c,做的一道练习题,因为有java基础,所以有些解题思路,但具体的语言写法不怎么会,求高手指导一二,非常感谢.

查询出最高分数的学生信息

#define STUDENT_SIZE (3)
typedef struct ScoreInfo{//分数信息 
	int mathScore;
	int chineseScore;
	int englishScore;
}ScoreInfo;
typedef struct StudentInfo{//学生信息  包含分数信息 
	char stuName[10];
	int stuID;
	int stuAge;
	ScoreInfo stuScore;
}StudentInfo;
void displayStuInfo(StudentInfo stu[],int pos);		//打印最高分学生详细信息
bool sumScore(StudentInfo* pStu,int *pSumArray);	//计算总分
int findFirst(StudentInfo* pStu);	//查找最高分数的学生  返回学生序号
int main(){
	StudentInfo stuArray[STUDENT_SIZE]=({"Lisa",1,12,{25,80,75}},
                                        {"Tom",2,13,{85,70,80}},
                                        {"Lucy",3,12,{100,90,99}});
	int pos=0;	
	pos=findFirst(   ); 	//①
	if(   ){  //②
		printf("\nError,please check");
	}else{
		displayStuInfo(stuArray,pos);	//打印最高分学生详细信息
	}
	return 0;
}
bool sumScore(StudentInfo* pStu,int *pSumArray){
	if(NULL==pStu){
		return false;
	}
	if(NULL==pSumArray){
		return false;
	}
	int i=0;
	for(i=0;i<STUDENT_SIZE;i++){
		pSumArray[i]=(       );  //③
	}
	return true;
}
int findFirst(StudentInfo* pStuArray){
	if(NULL==pStuArray){
		return -1;
	}
	int sumArray[STUDENT_SIZE]=      ;     //④
	int firstPos=0;
	int ret=true;
	int maxScore=0;
	int t;
	
	if(false==sumScore(       )){    //⑤
		return -1;
	}
	maxScore=sumArray[0];
	for(i=1;i<STUDENT_SIZE;i++){
		if(maxScore<sumArray[i]){
			maxScore=sumArray[i];	
			                     //⑥记录位置 
		}
	}
	return firstPos;
}
void displayStuInfo(StudentInfo stu[],int pos){
	printf("\n  name:%s",stu[pos].stuName);
	printf("\n  ID:%d",stu[pos].stuID);
	printf("\n  Age:%d",stu[pos].stuAge);
	printf("\n Math %d",            );           //⑦
	printf("\n Chinese %d",           );     //⑧ 
	printf("\n English %d",           );      //⑨
}

}

在数据结构中加了一个变量，这样所有的函数都跟着变化。 可以参考一下，有问题继续提出来。
