求:C语言破译密码程序

#include<顷衫stdio.h>雀汪腔

int main()

{

char s

while((s=getchar())!='!')

{

if(s>='a'&&s<'z')

++s

else if(s=='z')

s='a'

else if(s>='A'&&s<'Z')

++s

else if(s=='Z')

s='A'

printf("%c"陵尘,s)

}

printf("!")

}

调了半天，楼主真是太粗心了！middle1[]应该这锋春样声明渣源：

char middle1[]={'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','如基态U','V','W','X','Y','Z'}

最后输出start的时候要注意控制长度，改个for循环就好了！

#include<stdio.h>

#include<string.h>

int main(void)

{

int i,j,length,n

char temp

char middle2[27]

char start[201],finish[201]

char middle1[]={'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'}

gets(middle2)

gets(finish)

scanf("%d",&n)

length=strlen(finish)

for(i=0i<25i++)

{

for(j=i+1j<26j++)

{

if(middle2[i]>middle2[j])

{

temp=middle2[i]

middle2[i]=middle2[j]

middle2[j]=temp

temp=middle1[i]

middle1[i]=middle1[j]

middle1[j]=temp

}

}

}

for(i=1i<=ni++)

{

for(j=0j<lengthj++)

{

if(finish[j]==' ')

{

start[j]=' '

}

else

{

start[j]=middle1[finish[j]-'A']

}

}

}

for( i = 0i <length++i)

printf("%c",start[i])

printf("\n")

return 0

}
