1、T061、文件比较#include#includeintmain(){FILE*p1,*p2;inti=1,j=1;charch1,ch2;p1=fopen("DATA5613.CPP","r");p2=fopen("DATA5613.TXT","r");while(!feof(p1)){ch1=fgetc(p1);ch2=fgetc(p2);if(ch1==''){i=1;j++;}elseif(ch1!=ch2)printf("%d%d",j,i);elsei++;}fclose(p1);fclose(p2);}T062、搜

2、索字符#includeintmain(){char*search(char*p,charch),a[300],ch,*p;gets(a);ch=getchar();p=search(a,ch);for(;*p==ch&&*p!='';p++)printf("%c",*p);printf("");return0;}char*search(char*p,charch){inti,max=0;char*pmax;while(*p!=''){i=0;while(*p==ch){i++;p++;}if(i>max){max=i;pmax=p-i;}p++

3、;}returnpmax;}T063、单词频次#include#includeintmain(){inti=0,j=0,k=0;FILE*p;charch;p=fopen("DATA5610.TXT","r");if(p==NULL){exit(0);}while(!feof(p)){ch=fgetc(p);if(ch=='i'){ch=fgetc(p);if(ch=='f'){i++;}}if(ch=='w'){ch=fgetc(p);if(ch=='h'){ch=fgetc(p);if(ch=='i'){ch=fgetc(p);if

4、(ch=='l'){ch=fgetc(p);if(ch=='e'){j++;}}}}}if(ch=='f'){ch=fgetc(p);if(ch=='o'){ch=fgetc(p);if(ch=='r'){k++;}}}}fclose(p);printf("%d%d%d",i,j,k);return0;}T064、检查图像文件格式T065、成绩表计算#includestructstu{longxh;charname[50];intage;doublea[7];doublesum;doubleaver;}b[10],*p;intmain(){inti,j

5、;doublemax;max=0;for(i=0;i<10;i++){b[i].sum=0;scanf("%ld%s%d",&b[i].xh,b[i].name,&b[i].age);getchar();for(j=0;j<7;j++){scanf("%lf",&b[i].a[j]);getchar();b[i].sum=b[i].sum+b[i].a[j];}b[i].aver=b[i].sum/7;if(b[i].sum>max)max=b[i].sum,p=&b[i];}printf("%ld%s%d",p->xh,p->name,p->age);for(i=0;i<

6、7;i++)printf("%.2lf",p->a[i]);printf("");return0;}T066、重组字符串#includeintmain(){chara[300],b[300]={''};voiddel(char*,char*);gets(a);del(a,b);puts(b);return0;}voiddel(char*s,char*t){inti=0;while(*s!=''){if(i=1&&*s%2!=0)*t=*s,t++,i=0;s++;}}T067、源程序添加行号#includeintmain(){

7、chars1[100],s2[110];intcnt=0;FILE*in,*out;in=fopen("DATA5612.CPP","r");if(in!=NULL){out=fopen("DATA5612.TXT","w");while(!feof(in)){if(fgets(s1,sizeof(s1)-1,in)==NULL)continue;sprintf(s2,"%04d%s",++cnt,s1);fputs(s2,out);}fclose(out);fclose(in);}return0;}T068、字符
