有以程序#include#includetypedefstruct{charname[9];charsex;floatscore[2];}STU;voidf(STUa){STUb={“Zhao”,’m’,85.0,90.0};inti;strcpy(a.name,b.name);a.sex=b.sex;for(i=0;i<2;i++)a.score[i]=b.score[i];}main(){STUc={“Qian”,’p’,95.0,92.0};f(c);printf(“%s,%c,%2.0f,%2.0f
”,c.name,c.sex,c.score[0],c.score[1]);}程序的运行结果是
”,c.name,c.sex,c.score[0],c.score[1]);}程序的运行结果是
举一反三
- 下面程序的运行结果是（）。#includestdio.h#includestring.htypedefstruct{charname[9];charsex;floatscore[2];}stu;stuf(stua){stub={“zhao”,’m’,85.0,90.0};inti;strcpy(a.name,b.name);a.sex=b.sex;for(i=0;i2;i++)a.score[i]=b.score[i];returna;}intmain(){s௲ 垎 뗐敔 敔垎�敘垎၈Ǔ瘓礀Ǡ 㰰Ǒ 㰰Ǒ ብ盂剦௬Ѐ 㼈௲ብ盂 Ѐ 㰰Ǒᰀ狣Ԝ盜Љ 䕄
- 中国大学MOOC: 写出下面程序执行后的运行结果。#include <stdio.h>struct STU {char name[10];int num;int Score;};int main(){struct STU s[5]={{"YangSan",20041,703},{"LiSiGuo",20042,580},{"wangYin",20043,680},{"SunDan",20044,550},{"Penghua",20045,537}},*p[5],*t;int i,j;for(i=0;i<5;i++) p[i]=&s[i];for(i=0;i<4;i++)for(j=i+1;j<5;j++)if(p[i]->Score>p[j]->Score){ t=p[i]; p[i]=p[j]; p[j]=t;}printf("%d %d",s[1].Score,p[1]->Score); return 0;}
- 有以下程序 struct STU { char num[10]; float score[3]; } main() { struct STU s[3]={{"20021",90,95,85},{"20022",95,80,75}, {"20023",100,95,90}},*p=s; int i; float sum=0; for(i=0;i<3;i++) sum=sum+p->score[i]; printf("%6.2f\n",sum); } 程序运行后的输出结果是
- 下面程序的运行结果是： 。 typedef union student{ char name[10]; long sno; char sex; float score[4]; }STU; main(){ STU a[5]; printf("%d",sizeof(a)); }
- 以下程序段，在空白处填写（）能使程序正确运行并输出结果。 #include struct student {long num; char name[10]; char sex; float score; }; main() {struct student stu={10101,"lili",'m',89.5},*pt; printf("%.2f",pt->score); }
