编程小问题

帮我看看这题的错误应该怎么改：#include <stdio.h>
#include <string.h>
#include <conio.h>
#include <ctype.h>

unsigned char xx[50][80];
int maxline=0;/*文章的总行数*/

int ReadDat(void);
void WriteDat(void);

void encryptChar()
{ int i,j;
for(i=0;i<maxline;i++)
for(j=0;j<strlen(xx[i]);j++)
if(xx[i][j]*11%256<=32||xx[i][j]*11%256>='a'&&xx[i][j]*11%256<='z') continue;
else xx[i][j]=xx[i][j]*11%256;
}

void main()
{

if(ReadDat()){
printf("数据文件ENG.IN不能打开！\n\007");
return;
}
encryptChar();
WriteDat();
}

int ReadDat(void)
{
FILE *fp;
int i=0;
unsigned char *p;

if((fp=fopen("eng.in","r"))==NULL) return 1;
while(fgets(xx[i],80,fp)!=NULL){
p=strchr(xx[i],'\n');
if(p)*p=0;
i++;
}
maxline=i;
fclose(fp);
return 0;
}

void WriteDat(void)
{
FILE *fp;
int i;

fp=fopen("ps5.dat","w");
for(i=0;i<maxline;i++){
printf("%s\n",xx[i]);
fprintf(fp,"%s\n",xx[i]);
}
fclose(fp);
}
用C++环境编的，(三级)

执行 cl.exe 时出错.

sdf.exe - 1 error(s), 0 warning(s)
用C++，但是int ReadDat(void)不能改，看下能调试出来吗，是计算机三级的

Answer 1

我也是初学啊，说错了别骂我
for(i=0;i<maxline;i++)
for(j=0;j<strlen(xx[i]);j++)
if(xx[i][j]*11%256<=32||xx[i][j]*11%256>='a'&&xx[i][j]*11%256<='z') continue;
else xx[i][j]=xx[i][j]*11%256;

for循环的{}对吗？不用把if...else...括上？
