when i input “yy” scanf() uses the second y automatically and doesn’t wait for another char input.

`while(1) {
    char response;

    printf("Start new blackjack game? y/n: ");
    scanf(" %1c", &response);
    if(response == 'y') {
        printf("game started!n");
    } else if(response == 'n') {
        break;
    } else {
        continue;
    }
 
 
}`

I tried to make scanf() take in one character as a yes or no input to start a blackjack game but it always uses old, unused characters that were inputed, and it only works when one character is inputed.
