Simple last Selector Looser game by using "c".

 Algorithm:-

1)Take i=21;
2) player 1 Enter the value among 1,2,3,4 as c1.
3) i=i-c1
4) Print remaining number after subtraction.
5) Player 2 enter the number among 1,2,3,4 as c2 but less than remaining after subtraction.
6) Repeated above process till i==0;
7) if process end after Player 1 selection then player 1 loose , else player2 loose.

CODE:-

#include <stdio.h>

int main()

{

    int i=21;

    int s1,s2;//r1,r2;

    while(i>0)

    {

        printf("Player 1 Enter the number 1,2,3,4=");

        scanf("%d",&s1);

       // printf("Player 2 Enter the number 1,2,3,4=\n");

       // scanf("%d",&s2);

        if(s1>=1 && s1<=4)

        {

        i=i-s1;

        if(i==0)

        {

            printf("\n                                    Player 1 Loose.     ");

            break;

        }

        printf(" ********please enter the value less than %d******** \n",i);

        }

        else

        {

        printf("********please Enter the number 1,2,3 and 4.********\n");

        }

        printf("Player 2 Enter the number 1,2,3,4=");

        scanf("%d",&s2);

        if(s2>=1 && s2<=4)

        {

         i=i-s2;

        if(i==0)

        {

            printf("\n                                        Player 2 Loose.");

            break;

        }

        printf("******** please enter the value less than %d********\n ",i);

        }

        else

        {

        printf("********please Enter the number 1,2,3 and 4.********\n");

        }

       // if(r1==0 || r2==0)

            //i==0;

    }

    

    return 0;
