1、输入学生信息（姓名，年龄，分数），并按照分数由高到低输出。#include#includestructstudent{intage;floatscore;charname[100];};input_stlen(int*num){printf("请输入学生总数：");printf("num=");scanf("%d",num);}input_stIFO(int*num,structstudent*p){inti;for(i=0;i<*num;i++){printf("请输入第%d学生信息：",i+1);printf("age:");scanf(

2、"%d",&p[i].age);printf("score:");scanf("%f",&p[i].score);printf("name：");scanf("%s",p[i].name);}}input_stcomp(int*num,structstudent*r){inti,j;structstudentt;printf("学生成绩排名如下：");for(i=0;i<*num-1;i++)for(j=0;j<*num-1-i;j++){if(r[j].score

3、*num,structstudent*Q){inti;printf("学生排名如下：");printf("-------------------------------------------------------------------");printf("%-20s%20s%20s","name:","age:","score:");for(i=0;i<*num;i++){printf("%-20s%20d%20f",Q[i].name,Q[i].age,Q[i].score);}}intmain(void){inti,j,len;structstudent*p

4、Arr,t;input_stlen(&len);//输入学生数pArr=(structstudent*)malloc(sizeof(structstudent)*len);//定义动态内存input_stIFO(&len,pArr);//输入学生信息input_stcomp(&len,pArr);//比较output_stARR(&len,pArr);//输出return0;}
