用c语言编写文字分类程序（从文件读入）

#include<stdlib.h>

main()

{

FILE *fp

int a,j,l

int flag

int s[a-1]

char i[a-1]

char k[a-1]

float pct[a-1]

char c

a=0

if ((fp=fopen("c:\\1.txt","r"))==NULL)

{printf ("can`t open")

exit(0)}

for (j=0!feof(fp)j++)

{

a++

c=fgetc(fp)

i[j]=c

k[j]= c

printf ("%c",c)

s[j]=0

pct[j]=0.0

}

printf ("\n共有塌禅绝%d个字符",a-1)

for (l=0l<(a-1)l++)

{

for (j=0j<(a-1)j++)

{ if (k[l]==i[j])

{ s[l]++}

}

}

printf("\nchar number percent\n")

for (l=0l<(a-1)l++)

{ flag=1

for (j=lj<=(a-1)j++)

{if (i[j]==i[l]&&l!=j)

{ flag=0

continue

}

}

if (flag!=0)

{

printf("%2c %6d \t\n",i[l],s[l])

}

}

}
