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("Outputdatatofile!");for

2、(i=0;i

3、");}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、clude#includevoidfun(char*s,char*t){inti,sl;sl=strlen(s);/************found************/for(i=0;i<=s1;i++)t[i]=s[i];for(i=0;i

5、intf("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(){/*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\240100

6、01\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#include#include#includevoidWriteText(FILE*);voidReadText(FILE*);main(){FILE*f

7、p;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);}ReadText(fp);fclose(fp);}/**********found**********/voidWri
