小练习-加减游戏

#include
int main(void)
{
    int a, b, c;
    char input[10];
        printf("Please enter two numbersn ");
        label1:
        printf("Number a:_____bbbbb");
        scanf_s("%d", &a);
        printf("Number b:_____bbbbb");
        scanf_s("%d", &b);
        printf("Please enter answer of sum these number:_____bbbbb");
        scanf_s("%d", &c);
        while (c != a + b) {
            printf("Please try again!:_____bbbbb");
            scanf_s("%d", &c);
        }
        printf("Your answer is right!n");
        printf("n");
        printf("Do you want it again?input:y/n?");
        getchar();
        c = getchar();
        if (c == 'y')
        {
            goto label1;
        }   
        else
    printf("program quit!n");
    return 0;
}

写了一个简单的小练习，但是看到相关的文章说，不建议使用goto，请各位大神帮忙看看，能否简化一下，小弟学习学习！谢谢！
