Answer Posted / chandrakala

this program returns the result as

1.

because,
7 is not equal to 1 or 0 and it is not mod by 2. so it will
go to else condition .in that 7-1 is performed and it mod
by 2 so 6/2=3 it once again go to else 3-1=2 is enter in to
function 2%2\=0 so 2/2 is performed.now v is 1 so it
returns 1 as answer.

how can I convert a string to a number?

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.
