我正在尝试编写这个程序来计算存款的简单利息.它应该将利息金额加到原始存款上.

但它继续使变量"速率"0,这就是为什么当我运行它,结果为0.任何帮助表示赞赏.

  #include <stdio.h>

int main(void){

    double d;
    double rate;
    double y;
    double final;
    int x;

    printf("Enter the deposit: ");
    scanf("%d", &d);

    printf("Enter the interest rate (0-100): ");
    scanf("%d", &rate);

    printf("Enter the number of years: ");
    scanf("%i", &x);

    rate = rate / 100;

    y = d * rate * x;

    final = d + y;


    printf("After %i number of years, the deposit in the savings account is now %d", x, rate);

}
