In the code n No initialization value , Revised as follows , For reference ：

#include <stdio.h>#include <string.h>int main(){    int  n = 0, j, i;    char a[100][100], t[100];    while (gets(a[n]) != NULL) //ctrl+Z  End input     {        n++;    }    for (i = 0; i < n - 1; i++)    {        for (j = i + 1; j < n; j++)        {            if (strcmp(a[i], a[j]) > 0)            {                strcpy(t, a[i]);                strcpy(a[i], a[j]);                strcpy(a[j], t);            }        }    }    for (i = 0; i < n; i++)    {        printf("%s\n", a[i]);    }    return 0;}
