To check if given string is palindrome or not. #include <stdio.h> #include <string.h> #include <conio.h> int main() { char a[100], b[100]; printf ( "Enter the string to check if it is a palindrome\n" ); gets (a); strcpy (b,a); strrev (b); if ( strcmp(a,b) == 0 ) printf ( "Entered string is a palindrome.\n" ); else printf ( "Entered string is not a palindrome.\n" ); return 0; }

To Find Factorial of a Number

To Find Factorial of a Number Factorial of a Number For any positive number n , its factorial is given by: factorial = 1 * 2 * 3 * 4. ... n If a number is negative, factorial does not exist and factorial of 0 is 1. This program takes an integer from a user. If user enters negative integer, this program will display error message and if user enters non-negative integer, this program will display the factorial of that number. Source Code /* C program to display factorial of an integer if user enters non-negative integer. */ #include <stdio.h> int main () { int n , count ; unsigned long long int factorial = 1 ; /* you can only write int */ printf ( "\nEnter an integer: \n" ); scanf ( "%d" ,& n ); if ( n < 0 ) printf ( "\nError!!! Factorial of negative number doesn't e...
