함 만들어 봤습니다. 참고하세요..
int main(int argc, char *argv[])
{
int length, i;
char word[40];
char new_word[40];
printf("Input a word : ");
scanf("%s", word);
// 전체 길이를 구함
length = strlen(word);
// 앞쪽은 그대로..
strcpy(new_word, word);
for(i=0; i<length; i++)
new_word[length+i] = word[length-i-1];
new_word[length*2] = 0;
printf("New word : %s\n", new_word);
}
[root@hackerschool HS_Boards]# ./test
Input a word : abc
New word : abccba
[root@hackerschool HS_Boards]# ./test
Input a word : mirable
New word : mirableelbarim
[root@hackerschool HS_Boards]#
