We want a function that takes as parameters two strings and return 1 if they are the same or 0 if they are not the same.
1 2 3 4 5 6 7 8 9 | int compare(char *word1,char *word2){ while(*word1 && *word2) if(*word1++ != *word2++) return 0; if(*word1==*word2) return 1; else return 0; } |

int compare(char *word1,char *word2){
while(*word1 && *word2 && word1++ == *word2++);
return(*word1-*word2);
}
