While declaring Pointer for an Integer value, we assign a
default size i.e 4 byte of memory for the Integer variable.
But in the case of char by default it assigns 1 byte of
memory for that character variable.

The type of declaration is the same for both.

Char a[5], *p; // for char variable
int *i; // for Int variable

printf(), scanf() these are a) library functions b) userdefined functions c) system functions d) they are not functions

using only #include and #include Write a program in C that will read an input from the user and print it back to the user if it is a palindrome. The string ends when it encounters a whitespace. The input string is at most 30 characters. Assume the string has no spaces and distinguish between and lowercase. So madam is a palindrome, but MadAm is not a palindrome. Use scanf and %s to read the string. Sample Test: Enter a string: madam madam is a palindrome. Enter a string: 09023 09023 is not a palindrome.
