Result says timeout but code is correct

Question

You are given the noises made by different animals that you can hear in the dark, evaluate each noise to determine which animal it belongs to. Lions say 'Grr', Tigers say 'Rawr', Snakes say 'Ssss', and Birds say 'Chirp'

Sample Input:
Rawr Chirp Ssss

Sample Output:
Tiger Bird Snake
Here is my code ;-
#include<stdio.h>
#include<string.h>
int main()
{
char p=getchar();
int q=0;
while(p!='\n')
{

char s[100];
scanf("%s",&s);
if(q==0){
char str[100];
str[0]=p;
strncat(str,s,strlen(s));
strcpy(s,str);
}
int a=strcmp(s,"Grr");
int b=strcmp(s,"Rawr");
int c=strcmp(s,"Ssss");
int d=strcmp(s,"Chrip");
// printf("%d",c);

if(a==0)
printf("Lion ");
else if(b==0)
printf("Tiger ");
else if(c==0)
printf("Snake ");
else if(d==0)
printf("Bird ");
q=1;
p=getchar();
}}

Answer 1

The why program cause 'Time out' is happened when you made infinity loop like while(true)

Answer 2

Got it but i have to use it

Answer 3

Is there any other option for this program?
