实验十一 文件操作程序设计实验(2)

ch=fgetc(fp);

if(ch>='A'&&ch<='Z'){

daxie++;}

else if(ch>='a'&&ch<='z'){

xiaoxie++;}

else if(ch>='0'&&ch<='9'){

shuzi++;}

else qita++;

}

if((fp=fopen("test.dat","w"))==NULL){

printf("File open error!\n");

exit(0);

}

fprintf(fp,"大写=%d\n小写=%d\n

=%d\n",daxie,xiaoxie,shuzi,qita);

if(fclose(fp)){

printf("Can not close the file!\n");

exit(0);

}

return 0;

}

或者

#include<stdio.h>

#include<stdlib.h>

int main()

{

FILE *fp1,*fp2;

char ch;

int daxie=0,xiaoxie=0,shuzi=0,qita=0;

if((fp1=fopen("src.dat","r"))==NULL){

数字=%d\n其它
