C未正确读取输入值

我对C非常陌生,在处理一个需要从控制台中提取不确定数量的值的项目时,我发现它没有提取正确的值。它看起来像地址,我相信这意味着这是一个指针问题,但我似乎找不到它。

int getVals(int degree){

        double sum;
        double x;
        double coefs[degree];
        for(int counter = 0; counter<=degree; counter = counter+1){
                double nxt;
                scanf(" %d", &nxt);
                coefs[counter] = nxt;
                printf("coefs[%d] = %d\n", counter, coefs[counter]);

        }
        printf(" x ? ");
        scanf(" %d", &x);
        printf("degree %d x %d\n", degree, x);
        sum = poly(x, degree, coefs);
                printf ("polynomial evaluate to: %lf\n", sum);
        int newDegree;
        scanf(" %d", &newDegree);
        degree = newDegree;
        if(degree>-1){
                getVals(degree);
        }
        else
                return degree;
}

注:poly返回评估多项式的双重结果 在输入次数1和系数1.5后,我得到以下无限循环。它不允许我输入x。 Infinite loop
