Answer 5

(*Javaria*) you are using an character array to store strings. Your program is allocating memory for 10 characters (not words).

Answer 6

(*Javaria*) you would need an 2D array to store strings.

Answer 7

I see no problem with using an array of pointers here? At least if you're not storing anything into it or plan to modify the strings.

const char *p[] = {
"books",
"pencils",
"pens",
"notebook",
"eraser"
};

The input is stored in the 'str' array which is then compared to p[i]. C++ is only warning you for not using const for the array, because it contains pointers to read-only strings.

Here's an example: https://code.sololearn.com/cKku39glhbzc/#cpp

C++ is strict about const and non-const conversions. I believe in C you would not get those warnings if you declared them as char *, but for safety reasons they should be const.

I believe the other reason was that you did strcmp(str, *p[i]) instead of p[i].
