☆题目11 程序prog1.c的功能是：把 s 字符串中的所有字母改写成该字母的下一个字母，字母z改写成字母a。要求大写字母仍为大写字母，小写字母仍为小写字母，其它字符不做改变。
请考生编写函数chg(char *s)实现程序要求，后调用函数readwritedat( )把结果输出到文件bc1.out中。
例如：s 字符串中原有的内容为：mn.123zxy，则调用该函数后，结果为：no.123ayz。
注意：部分源程序存在文件prog1.c文件中。
请勿改动主函数main( )和输出数据函数readwritedat()的内容。

&emspdefine n 81
void readwritedat();
void chg(char *s)
{int i;
for(i=0;i if(s[i]=='z'
s[i]=='z') s[i]-=25; else if(s[i]>='a'
}
main( )
{
char a[n];
clrscr();
printf("enter a string : "); gets(a);
printf("the original string is : "); puts(a);
chg(a);
printf("the string after modified : ");
puts (a);
readwritedat() ;
}
void readwritedat()
{
int i ;
char a[n] ;
file *rf, *wf ;
rf = fopen("bc1.in", "r") ;
wf = fopen("bc1.out", "w") ;
for(i = 0 ; i< 50 ; i++) {
fscanf(rf, "%s", a) ;
chg(a) ;
fprintf(wf, "%s\n", a) ;
}
fclose(rf) ;
fclose(wf) ;
