Questions:

$1.$ Apply the program in figure $6\mathrm{.}13$ and make it work.

$2.$ Take the entire string $$hello my name is Hakan Koyuncu$$ by using scanf$()$ function. $($research on google$)$

#include

int main$()\{$

char str$[100]$;

printf$("$Enter a string: $")$;

scanf$("\%[^$

$]",$ str$)$;

printf$("$You entered: $\%$s

$",$ str$)$;

$\}$

$3.$ Check if a string is palindrome $($example: Hannah, radar, etc.$)$

Homework: Check if the input sentence is a $$palindrome sentence$.($example: "Madam, I$\text{'}$m Adam." when considering palindrome sentence, spaces and punctuation are often ignored.$)($hint you can use isalnum$()$ function in ctype.h library$)$
