Problem Statement :
Write a program to reverse a number
Code:
#include <stdio.h>
int main(){
//18. Write a program to reverse a number.
int n, reverse=0 ,remainder;
printf("\tReverse A Number");
printf("\n========================================");
printf("\nEnter The Number : ");
scanf("%d",&n);
while(n != 0){
remainder = n%10;
reverse = (reverse*10) + remainder;
n /= 10;
}
printf("\n__________________________________________");
printf("\n\nReversed Number Is : %d",reverse);
printf("\n\n__________________________________________\n\n");
return 0;
}
Description :
- This is a C program that reverses a given integer number. The program prompts the user to input a number and then uses a while loop to reverse it. The variables
reverse,remainder, andnare declared and initialized to 0. In each iteration of the loop, the program calculates the remainder of the number when divided by 10, and then updates thereversevariable by multiplying it by 10 and adding the remainder. The program then divides the original numbernby 10 and continues the loop untilnbecomes 0. Finally, the program prints the reversed number to the console along with a message. The program ends by returning 0 to indicate that it has executed successfully.
