Palindrome number in C #include <stdio.h>   int   main ( ) {     int   n ,   reverse   =   0 ,   t ;       printf ( "Enter a number :  \n " ) ;     scanf ( "%d" ,   & n ) ;      t   =   n ;       while   ( t   !=   0 )     {       reverse   =   reverse   *   10 ;       reverse   =   reverse   +   t % 10 ;       t   =   t / 10 ;     }       if   ( n   ==   reverse )         printf ( "%d is a palindrome number. \n " ,   n ) ;     else         printf ( "%d isn't a palindrome number. \n " ,   n ) ;       return   0 ; } Output : Enter a number : 12321 12321  is a palindrome number.

C programming - Calculate Average Using Arrays Examples #include int main() { int n, i; float num[100], sum = 0.0, average; printf("Enter the numbers of elements: "); scanf("%d", &n); while (n > 100 || n Output Enter the numbers of elements: 6 1. Enter number: 45.3 2. Enter number: 67.5 3. Enter number: -45.6 4. Enter number: 20.34 5. Enter number: 33 6. Enter number: 45.6 Average = 27.69
