1、第1套题一、程序填空题#include#include#defineN5typedefstruct{intnum;charname[10];chartel[10];}STYPE;voidcheck();/**********found**********/intfun(___1___*std){/**********found**********/___2___*fp;inti;if((fp=fopen("myfile5.dat","wb"))==NULL)return(0);printf("Outputd

2、atatofile!");for(i=0;i

3、ucceed!");check();}elseprintf("Fail!");}voidcheck(){FILE*fp;inti;STYPEs[10];if((fp=fopen("myfile5.dat","rb"))==NULL){printf("Fail!!");exit(0);}printf("Readfileandoutputtoscreen:");printf("numnametel");for(i=0;i

4、",s[i].num,s[i].name,s[i].tel);}fclose(fp);}二、程序改错题#include#includevoidfun(char*s,char*t){inti,sl;sl=strlen(s);/************found************/for(i=0;i

5、s[100],t[100];printf("Pleaseenterstrings:");scanf("%s",s);fun(s,t);printf("Theresultis:%s",t);}三、程序编写题#includevoidfun(inta,intb,long*c){}main(){inta,b;longc;voidNONO();printf("Inputab:");scanf("%d%d",&a,&b);fun(a,b,&c);printf("Theresultis:%d",c);NONO();}voidNONO

6、(){/*本函数用于打开文件，输入数据，调用函数，输出数据，关闭文件。*/FILE*rf,*wf;inti,a,b;longc;rf=fopen("K:\k01\24010001\in.dat","r");wf=fopen("K:\k01\24010001\out.dat","w");for(i=0;i<10;i++){fscanf(rf,"%d,%d",&a,&b);fun(a,b,&c);fprintf(wf,"a=%d,b=%d,c=%ld",a,b,c);}fclose(rf);fclose(wf);}第2套题一、程序填空题

7、#include#include#includevoidWriteText(FILE*);voidReadText(FILE*);main(){FILE*fp;if((fp=fopen("myfile4.txt","w"))==NULL){printf("openfail!!");exit(0);}WriteText(fp);fclose(fp);if((fp=fopen("myfile4.txt","r"))==NULL){printf("openfail!!");exit(0);

8、}ReadText(fp);fclose(fp);}/**********found**********/voidWrit
