我们所设计的程序是《小学生四则运算》。此程序由加减乘除法构成，每种算法又由一位数与一位数运算，一位数与两位数运算，两位数与两位数运算组成。本程序由我，罗莹，韩磊，分工完成其中我负责加减法的编制。在这里，我们涉及到了多种函数的调用。-We are design program is the primary school students arithmetic ". This procedure by add, subtract, multiply and divide method constitute, each algorithm by single digits and with a digit calculation, the single digits and two digits operations, two digits and two digits of operation. This procedure by me, LuoYing, HanLei, division of I am responsible for the complete of addition and subtraction. Here, we involved a variety of function calls.
