我的作业如下：

#include <stdio.h>
int main()
{
    float money,duration,rate,total;
	printf("Please enter your desposit amount(yuan) and duration(month).\n");
	scanf("%f,%f",&money,&duration);
	if (duration<3) rate=0.003;
	    else if (duration<6) rate=0.0135;
	 	    else if (duration<12) rate=0.015;
	 		    else if (duration<24) rate=0.0175;
	 			    else if (duration<36) rate=0.0225;
	 				    else rate=0.0275;
	total=money+money*rate*duration/12;
	printf("total=%.2f",total);
}
