看到有些解法是先将字符中的重复的去除，我这里用一个数组标志一下有相同的效果。

#include <stdio.h>
#include <string.h>
int dict[256];
void main()
{
int i;
char src[1280];
int error;
int correct;
char guess[1280];
int round;
int t;
memset(dict,0,sizeof(int)*256);
scanf("%d",&round);
scanf("%s",src);
scanf("%s",guess);
while(round!=-1){
error=0;
correct=0;
memset(dict,0,sizeof(int)*256);
for(i=0;i<strlen(src);i++){
if(dict[src[i]]==0) correct++;
dict[src[i]]=1;
}
for(i=0;i<strlen(guess);i++){
t=dict[guess[i]];
if(t==0){
error++;
dict[guess[i]]=-2;
}else if(t==1){
correct--;
dict[guess[i]]=-1;
}
if(correct==0||error>=7) break;
}
printf("Round %d\n",round);
if(correct==0){
printf("You win.\n");
}else if(error>=7){
printf("You lose.\n");
}else{
printf("You chickened out.\n");
}
scanf("%d",&round);
scanf("%s",src);
scanf("%s",guess);
}
}
