Card Game - XI

Patrick and Johnny started to play a card game-XI. In this game, Patrick and Johnny have to pick one card each. The game rule is as follows

i) If both card numbers are positive, reverse the digits in two card numbers and display their sum

ii) If one card number is negative, reverse the digits in positive card number and reverse the sign of negative card number, finally display their sum

iii) If both card numbers are negative, reverse the sign the two negative card number and display their sum. They approach you and ask for your help.

Can you please help them?

Write a C program to reverse a given two number as per above game rules and display their sum using while loop.

Input Format:

Input consists of 2 integers.

The first input consists of an integer, which corresponds to the card number picked by Patrick.

The first input consists of an integer, which corresponds to the card number picked by Johnny.

Output Format:

Output consists of a single integer, which corresponds to the sum. The leading 0's are omitted.

[All text in bold corresponds to the input and the rest corresponds to output]

Sample Input and Output 1:

Enter the card number picked by Patrick:

456

Enter the card number picked by Johnny:

32

Sum is 677

 

Sample Input and Output 2:

Enter the card number picked by Patrick:

-56

Enter the card number picked by Johnny:

450

Sum is 110

Sample Input and Output 3:

Enter the card number picked by Patrick:

-56

Enter the card number picked by Johnny:

-789

Sum is 845

Program Code:

#include <stdio.h>

#include<stdlib.h>

int reversDigits(int num)

{

    int rev_num = 0;

    while(num > 0)

    {

        rev_num = rev_num*10 + num%10;

        num = num/10;

    }

    return rev_num;

}

int main()

{

    int num1, num2, sum;

    printf("Enter the card number picked by Patrick:\n");

    scanf("%d", &num1);

    printf("Enter the card number picked by Johnny:\n");

    scanf("%d", &num2);

    if(num1<0)

    num1=abs(num1);

    else

    num1= reversDigits(num1);

    if(num2<0)

    num2=abs(num2);

    else

    num2= reversDigits(num2);

    sum = num1+num2;

    printf("Sum is %d", sum);

    return 0;

}
