why after looping there's a newline

so i'm trying to make a penalty kick scorekeeper. i set it to be 5 rounds at first, and when the scores are tied, it will repeat another 5 rounds. the problem is there's seem to be a newline appeared after it.

#include <stdio.h>

int main()
{
    int penalty2=0,penalty1=0,i=0;
    char home[15]="HOME",away[15]="AWAY";

    printf("\nSTARTS PENALTY SHOOTOUT\n\n\t\t%s\t\t VS\t\t %s\n\n",home,away);
    do{
        char penal1=' ',penal2=' ',penal3=' ',penal4=' ',penal5=' ',penal6=' ',penal7=' ',penal8=' ',penal9=' ',penal10=' ';
        for(i=1;i<=10;++i)
        {
            printf("\nEnter X for MISS and O for GOAL\n\n:>>");
            if(i==1)
            {
                scanf("%c",&penal1);
                printf("\n\n%-15s\t\t %c %c %c %c %c \n-------------------------------------\n%-15s\t\t %c %c %c %c %c \n\n",home,penal1,penal2,penal3,penal4,penal5,away,penal6,penal7,penal8,penal9,penal10);
                if (penal1=='O'||penal1=='o')
                {
                    ++penalty1;
                }
            }
            else if(i==2)
            {
                scanf(" %c",&penal6);
                printf("\n\n%-15s\t\t %c %c %c %c %c \n-------------------------------------\n%-15s\t\t %c %c %c %c %c \n\n",home,penal1,penal2,penal3,penal4,penal5,away,penal6,penal7,penal8,penal9,penal10);

On the 2nd time through the loop, scanf("%c",&penal1); is scanning in the '\n' from the previous user input. Add a preceding space like code used in other places to consume all preceding white-space.

scanf(" %c",&penal1);  // added space.

Code should check not only for 'O' and 'o', but 'X' and 'x' to be certain some other input did not occur.
