C++ program to reverse the number entered by the user, then displays the reversed number on the screen.
For example, if the user enters 678 as input, 876 is displayed as output. We use the mod(%) operator in the program to get the digits of an integer.
C++ Program Code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | #include<iostream> using namespace std; int main() { int n, reverse=0, rem; cout<<"Enter a number: "; cin>>n; while(n!=0) { rem=n%10; reverse=reverse*10+rem; n/=10; } cout<<"Reversed Number: "<<reverse<<endl; return 0; } |
Output:
1 2 3 4 | Enter a number: 12345 Reversed Number: 54321 |
