#define N 80
int main()
{
    char arr[N] ,ch ;
    int i = 0 ,flag = 0;
    printf("input char : ") ;
    scanf("%c",&ch) ;
    getchar() ;
    gets(arr) ;
    while(arr[i] != '\0')
    {
        if(ch == arr[i])
        {
            flag = i;


        }
        i++ ;

    }

   if(flag >= 0)
      printf("%d\n",flag);
   else
      printf("Not Found\n");
