Finding reverse number means for example take 123 then we need to get 321 is its reverse number. In c programming we can do it by using for loop and while loop. Lets us see an example C program to get reverse number of a number by using while loop and for loop. while(n != 0) { rem = n%10; reverse_Number = reverse_Number*10 + rem; n /= 10; }
Program #1 : Write a c program to reverse number using for loop. #include <stdio.h> // www. instanceofjava.com all rights reserved int main() { int n, reverse_Number = 0, rem,Original_number=0; printf("Enter a number to get reverse number "); scanf("%d", &n); Original_number=n; while(n != 0) { rem = n%10; reverse_Number = reverse_Number*10 + rem; n /= 10; } printf("Reversed Number of %d is = %d",Original_number=0;,reverse_Number); getch(); } Output: Program #2 : Write a C program to reverse a number using for loop #include <stdio.h> // www. instanceofjava.com all rights reserved int main() { int n, reverse_Number = 0, rem,Original_number=0; printf("Enter a number to get reverse number "); scanf("%d", &n); Original_number=n; for(;n != 0;) { rem = n%10; reverse_Number = reverse_Number*10 + rem; n /= 10; } printf("Reversed Number of %d is = %d",Original_number,reverse_Number); getch(); } Output: Enter a number to get reverse number 123987 Reversed Number of 123987 is = 789321
