Try that.

    do{

        int rows[] = {0, 3, 5, 7};
        int i, j;
        int player =1;
        int rowChosen, sticksChosen;
        int sum;

        printf("\n\n");
        printf("\t\t******************************\t");
        printf("\n\t\t****WELCOME TO GAME OF NIM****\t\t\n");
        printf("\t\tErvin Ardiente & Orven Dumasig\t\n");
        printf("\t\t******************************\t\n\n");

        sum=rows[1]+rows[2]+rows[3];

        while(sum>0)
        {

           for(i = 1; i <=3; i++)
           {
              if(rows[i])
              {
                 printf("\nRow %d:", i);
                 for(j = 0; j < rows[i] ; j++)
                 {
                    printf("\t|");
                 }
                 printf("\n");
              }
           }
           printf("\n");

           printf("\nPlayer %d's turn! \n\n",player);
           player++;
           if(player == 3)
           {
                player = player - 2;
           }
           printf("Please Enter a Row: ");
           scanf("%d", &rowChosen);

        while(rowChosen > 3 || rowChosen < 1 || rows[rowChosen]== 0)
        {
            printf("Error! Please enter a row with sticks: ");
            scanf("%d", &rowChosen);
        }

        printf("Please Enter Number of sticks to remove: ");
        scanf("%d", &sticksChosen);

        while(sticksChosen > rows[rowChosen] || sticksChosen < 1)
        { 
            printf("Error! Please Enter Number of sticks to remove: ");
            scanf("%d", &sticksChosen); 
        }    
        rows[rowChosen] -= sticksChosen;
        sum -= sticksChosen;

        if(sum==0)
            {
                printf("\n\nPlayer %d You lose!\n\n", player);
            }
        }

        printf("Do you want to try again? (Y/N)");
        scanf(" %c", &ans);

    }while (ans == 'Y' || ans == 'y');

 return 0;

}

Note that I moved all the rows up by one, so rows[0] is empty and not part of the game, anymore.

@Adak, Sir the the one who will picks the last stick will be the looser not the one who gets last.

I got the problem:

Player 2 turn:

Row1: I
Row2:
Row3:

Enter row: 1
Enter sticks to remove: 1

Player 2 is the looser.

My code actually says: Player 1 is the looser. how come? T.T the player 2 must be the looser cause he/she picks the last stick.

Code:

  if(sum == 0)
            {
                printf("\n\nPlayer %d You lose!\n\n", player);
            }

What are you trying to say?..

Code:

            for(i = 0; i < 3; i++)
                {
                    if(rows[i] ==0) 
                        {
                            printf("\nRow %d:", i+1);
                            for(j = 0; j < rows[i] ; j++)
                        {
                            printf("\t|");
                        }

                            printf("\n");
                        }
                }

is this what you try to say? or what?..

@Adak, oh the program works sorry for not reading it.. now i know.
But i wanted that the row1: (empty) and it not part of the game anymore,
do you have an idea?..

It deleted the row i wanted that the row is still there but its not part of the game anymore..
anyone?

Code:

#include <stdio.h>


int main ()
{

    char ans;

    do{

        int rows[] = {0, 3, 5, 7};
        int i, j;
        int player =1;
        int rowChosen, sticksChosen;
        int sum;

        printf("\n\n");
        printf("\t\t******************************\t");
        printf("\n\t\t****WELCOME TO GAME OF NIM****\t\t\n");
        printf("\t\tErvin Ardiente & Orven Dumasig\t\n");
        printf("\t\t******************************\t\n\n");

        sum=rows[1]+rows[2]+rows[3];

        while(sum>0)
        {

           for(i = 1; i <=3; i++)
           {
              if(rows[i])
              {
                 printf("\nRow %d:", i);
                 for(j = 0; j < rows[i] ; j++)
                 {
                    printf("\t|");
                 }
                 printf("\n");
              }
           }
           printf("\n");

           printf("\nPlayer %d's turn! \n\n",player);
           player++;
           if(player == 3)
           {
                player = player - 2;
           }
           
           printf("Please Enter a Row: ");
           scanf("%d", &rowChosen);

        while(rowChosen > 3 || rowChosen < 1 || rows[rowChosen]== 0)
        {
            printf("Error! Please enter a row with sticks: ");
            scanf("%d", &rowChosen);
        }

            printf("Please Enter Number of sticks to remove: ");
            scanf("%d", &sticksChosen);

        while(sticksChosen > rows[rowChosen] || sticksChosen < 1)
        {
            printf("Error! Please Enter Number of sticks to remove again: ");
            scanf("%d", &sticksChosen);
        }

        rows[rowChosen] -= sticksChosen;
        sum -= sticksChosen;

        if(sum==0)
            {
                printf("\n\nPlayer %d You lose!\n\n", player);
            }
        }

        printf("Do you want to try again? (Y/N)");
        scanf(" %c", &ans);

    }while (ans == 'Y' || ans == 'y');

 return 0;

}

One problem also is, when it declared the looser the looser will be the one who picks the
last stick not the one who is not picking the stick anymore..

This doesnt delete any of sticks in a row.
