long num, reverse = 0, temp, remainder;
printf("Enter the number\n");
temp = num;
while (num > 0)
remainder = num % 10;
reverse = reverse * 10 + remainder;
num /= 10;
printf("Given number = %ld\n", temp);
printf("Its reverse is = %ld\n", reverse);
$ cc pgm42.c $ a.out Enter the number 567865 Given number = 567865 Its reverse is = 568765
