Entering inputs

input.c

  int main(void){ 
  //enter number of times input with propmpt for string
    int count;
    puts("Enter count: ");
    scanf("%i", &count);
//  hack so it does not shallow fget
    getchar();
     // 1000 is arbitraty
    char arr[count][1000];
    for (size_t i = 0; i < count; i++)
    {
        char storeStrTemp[256];
//        reset arr
        memset(storeStrTemp, 0, sizeof(storeStrTemp));
        puts("enter str:");
//       NEED STR LEN HERE
        fgets(storeStrTemp, 256, stdin);
//         NEED STR LEN HERE TOO TO LOOP OVER IT ALL - it stops at 255
        for (size_t j = 0; j < strlen(storeStrTemp); j++)
        {
            arr[i][j] = storeStrTemp[j];
        }
    }
  }

Line 12 is the reason that you cannot take a string longer than 256 bytes. if you want to take a string longer than that, you'll have to allocate a buffer of memory to store it that is bigger. You can also do it dynamically -- ie, get their input one character at a time and then realloc() the buffer every time until there are no more characters left.
