Write a c program where program should read four digit number and display those entered number into reverse order.

C Code

#include<stdio.h>
#include<conio.h>
int main(void){

        int number;

        printf("Enter a four digit number:");
        fflush( stdout );
        scanf("%d", &number);

        printf("the number in reversed order:");

        printf("%d", number%10);
        number = number/10;

        printf("%d", number%10);
        number = number/10;

        printf("%d", number%10);
        number = number/10;

        printf("%d", number%10);

        return 0;
}

Output

When a user enters the value 1234
there is printf(“%d”,number%10); statement is used. It shows the value 4 because when 1234 is divided by 10 remainders is 4.
after that number = number / 10 display value 4…
the value of the number becomes 123 this process is repeated 3 times and the final output will be 4321

Write a C program to read a three-digit number and display it in reverse order.

C Code

#include<stdio.h>
#include<conio.h>
void main(){

        int number;

        printf("Enter a three digit number:");
        fflush( stdout );
        scanf("%d", &number);

        printf("the number in reversed order:");

        printf("%d", number%10);
        number = number/10;

        printf("%d", number%10);
        number = number/10;

        printf("%d", number%10);

        getch();
}
