宁波网站设计公司排名什么是seo营销

本周仅仅进行一个程序，曾经的一个程序。

自己定义例如以下函数，输入n(n<46)个学生的姓名和成绩，顺序输出这n个学生的姓名和成绩，并输出最高成绩的姓名和成绩。预习struct结构体，思考怎样改进这一程序。

 //为count个学生输入姓名和成绩void getStudentsInfo(char names[][20], int scores[] , int count);void getStudentsInfo(char* names[], int scores[] , int count);//依次打印count个学生的姓名和成绩 
void printStudentsInfo(char* names[], int scores[],int count); 
//获取最高成绩的学生的index 
int getIndexOfMaxScore(int scores[],int count);

知识点：
1 字符串数组用于处理多个人的姓名
2 数组作为函数的參数

the core code:

/* Note:Your choice is C IDE */
#include "stdio.h"void inputStudents(char name[][20],int score[],int num);
void outputStudents(char name[][20],int score[],int num);
main()
{char name[45][20];int  score[45];inputStudents(name,score,2);outputStudents(name,score,2);}void inputStudents(char name[][20],int score[],int num){int i ;for(i=0;i<num;i++)scanf("%s %d",name[i],&score[i]);
}
void outputStudents(char name[][20],int score[],int num){int i ;for(i=0;i<num;i++)printf("%s %d",name[i],score[i]);
}

an example :

/* Note:Your choice is C IDE */
#include "stdio.h"
#define N 45int inputSS(char names[][20],int score[],int num);
void printSS(char names[][20],int score[],int num);
void getMAX(char names[][20],int score[],int num);main()
{char names[N][20];int score[N];int num=0; int choose;printf("What do you want to do: INPUT(1),OUTPUT(2),MAX(3),EXIT(0):");scanf("%d",&choose);do{switch(choose){case 1:  num = inputSS(names,score,num);break;case 2:printSS(names,score,num);break;case 3:getMAX(names,score,num);}printf("\nWhat do you want to do: INPUT(1),OUTPUT(2),MAX(3),EXIT(0):");scanf("%d",&choose);}while(choose != 0);}
int inputSS(char names[][20],int score[],int num){int n,i;printf("\nThis Time, How many students do you want to input :");scanf("%d",&n);if((n+num)>N || n <1){printf("not valid sum\n");return -1;}printf("NOW INPUT AS ( NAME SCORE ):\n");for(i=0;i<n;i++){printf("%d. ",i);scanf("%s %d",&names[i+num],&score[i+num]);}printf("THIS TIME , INPUT IS OVER\n");return num+n;
}
void printSS(char names[][20],int score[],int num){int i ;if(num==0) {printf("NO STUDENTS NOW\n");return;}printf("\nNOW , THE STUDENTS SCORES AS FOLLOWS \n");for(i = 0 ;i<num;i++)printf("%2d. name:%10s score:%3d\n",i,names[i],score[i]);
}
void getMAX(char names[][20],int score[],int num){int i ,max_index,max_score;if(num==0) {printf("NO STUDENTS NOW\n");return;}max_index=0;max_score=score[0];for(i = 1 ;i<num;i++)if( score[i] > max_score ){max_score = score[i];max_index = i;}printf("The Top Score is %d  by %s \n",score[max_index],names[max_index]);}
