实现一个简单的整数计算器，能够进行加、减、乘、除和乘方运算。使用时算式采用后缀输入法，每个操作数、操作符之间都以空白符分隔。例如，若要计算"3+5"则输入"3 5 +"。乘方运算符用"^"表示。每次运算在前次结果基础上进行，若要将前次运算结果清除，可键入"c"。当键入"q"时程序结束。-A simple integer calculator capable of addition, subtraction, multiplication, addition to computing and power. Use the formula using the suffix input method, each operand, the operator between the blank-delimited. For example, to "3+5", enter "35+". Involution operator "^". Each operator on the basis of previous results to the previous result of the operation to clear, you can type "c". Type "q" end of the process.
