#include<conio.h>
int i=1;
void main()
{
i<=100 ? printf("%d\n",i) : getch(); //conditional operator
i++;
main(); //recursive calling of main() function
}

What are the output(s) for the following ? #include char *f() {char *s=malloc(8); strcpy(s,"goodbye")} main() { char *f(); printf("%c",*f()='A'); }

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.
