一个计算收益复利的小例子， 用c语言简单编程， 如 test 30 20 40；
30以万为单位，20是年收益百分比，40是年数。
#include <stdio.h>
#include <stdlib.h>#define YEAR_GET_TYPE 0 // 年测试类型// 年的计算
#ifdef YEAR_GET_TYPE
#define NAME "YEAR" // 年名称
#define YEAR_TIMES 40 // 年数
#define YEAR_GET 20 // 年率
#else
// 月的计算
#define NAME "MOON" // 月名称
#define YEAR_TIMES 12 // 月数
#define YEAR_GET 3 // 月率
#endif//#define YEAR_WASTE 120000 // 年花费
//#define TATOL_NUM 1000000 // 总额#define YEAR_WASTE 0 // 年花费
#define TATOL_NUM 300000 // 总额int main(int argc, char* argv[])
{float fYearGet = ((float)YEAR_GET) / 100; // 百分比年率float fTatolNum = TATOL_NUM;int nYearNum = YEAR_TIMES;if (2 == argc){fTatolNum = atoi(argv[1])*10000;}else if (3 == argc){fTatolNum = atoi(argv[1]) * 10000;fYearGet = ((float)atoi(argv[2])) / 100; // 百分比年率}else if (4 == argc){fTatolNum = atoi(argv[1]) * 10000;fYearGet = ((float)atoi(argv[2])) / 100; // 百分比年率nYearNum = atoi(argv[3]);}printf("-----------------------------yearget------------------------------------\n");printf("test.exe 30 20 or test.exe 30 20 40 -----------\n");printf("TATOL_NUM:%.0fw ", fTatolNum/10000);printf("%s_GET:%.2f%%\n", NAME, fYearGet * 100);printf("%s_WASTE:%d ", NAME, YEAR_WASTE);printf("%s_TIMES:%d\n", NAME, nYearNum);printf("------------------------------------------------------------------------\n");// 总记录printf("%s%d tatol = %f \n", NAME, 0, fTatolNum);for (int i = 0; i < nYearNum; i++){// 计算剩余fTatolNum = fTatolNum * (1 + fYearGet) - YEAR_WASTE;//打印换行if ((i != 0) && (0 == i % 10)){printf("\n");}// 打印printf("%s%d tatol = %f \n", NAME, i + 1, fTatolNum); }getchar();return 0;
}
运行结果如下：
