我的程序:

#include<stdio.h>
#include<string.h>
int main() {
const char m[][31]={ "",    ".-",  "-...","-.-.","-..", ".",   "..-.","--.",
"....","..",  ".---","-.-", ".-..","--",  "-.",  "---", ".--.","--.-",".-.",
"...", "-",   "..-", "...-",".--", "-..-","-.--","--..","..--","---.",".-.-",
"----"};
char u[100][100];
char tmp[400],tmp2[100],tmp3[4];
int i,j,k,n,t,len,l[100],lu,a,b;
scanf("%d",&n);
n--;
for(i=0;i<=n;i++)
  scanf("%s",&u[i]);
for(i=0;i<=n;i++){
  strset(tmp,'\0');
  strset(tmp2,'\0');
  lu=strlen(u[i]);
  len=0;
  for(j=0;j<=lu-1;j++){
    if((u[i][j]-64<=26)&&u[i][j]>64)t=u[i][j]-64;
      else switch(u[i][j]){
	     case'_':t=27;break;
	     case'.':t=28;break;
	     case',':t=29;break;
	     case'?':t=30;break;
      }
    l[j]=strlen(m[t]);
    len+=l[j];
    strcat(tmp,m[t]);
  }
  b=-1;
  for(j=lu-1;j>=0;j--){
    a=b+1;
    b=a+l[j]-1;
    tmp3[0]=tmp3[1]=tmp3[2]=tmp3[3]='\0';
    for(k=a;k<=b;k++)
      tmp3[k-a]=tmp[k];
    for(k=1;k<=30;k++)
      if(strcmp(tmp3,m[k])==0){
	if(k<=26)t=k+64;
	  else switch(k){
		 case 27:t='_';break;

	  }
	tmp2[lu-j-1]=t;

      }
  }
  strcpy(u[i],tmp2);
  u[i][lu]='\0';
}
for(i=0;i<=n;i++)
  printf("%s\n",u[i]);
}
