我刚刚开始学习C。因此，为了进行练习，我决定编写一个利率计算器，但由于某种原因，我的计算结果始终为0，因此我无法弄清楚。如果可以的话请看一看。

#include <stdio.h>


main()
{


int time;
float principle, rate, total;

printf("What is your starting amount? ");
scanf(" %f", &principle);
printf("What is your interest rate? ");
scanf(" %f", &rate);
printf("How long do you want to save? ");
scanf(" %d", &time);

total = principle * rate * time;
printf("You will have earned an interest amount of $%d", total);
return 0;
}

最佳答案

printf("You will have earned an interest amount of $%d", total);

由于total是浮点型，因此%d应该是%f。另外，在每行的末尾添加新行也是一种不错的感觉。

printf("You will have earned an interest amount of $%f\n", total);
