Example of Infix to Postfix Conversion Let's take an example to better understand the algorithm Infix Expression:A+(B*C-(D/E^F)*G)*H, where^is an exponential operator. Step by step output for infix to postfix conversion Input StringOutput StackOperator Stack ...
char infix[] = "a+b*(c^d-e)^(f+g*h)-i"; infixToPostfix(infix); return 0; } 相关问题与解答: 1、什么是中缀表达式和后缀表达式? 答:中缀表达式是运算符位于操作数中间的表示方式,而后缀表达式(逆波兰表示法)则是运算符位于操作数之后的表示方式。

在main函数中,我们通过scanf函数读取用户输入的中缀表达式,并将其存储在infix数组中。 4. 调用转换函数 调用infixToPostfix函数,将读取到的中缀表达式转换为后缀表达式,并存储在postfix数组中。 5. 输出或返回转换后的后缀表达式 在main函数的最后,通过printf函数输出转换后的后缀表达式。 以上代码实现了中缀表达式到后缀...
string infixToPostfix(string infix) { stringstream postfix; stack<char> opStack; for (int i = 0; i < infix.length(); i++) { char ch = infix[i]; if (isOperator(ch)) { while (!opStack.empty() && isOperator(opStack.top()) && getPriority(opStack.top()) >= getPriority(ch)) ...
infixToPostfix(infixExp, postfixExp); printf("后缀表达式为:%s\n", postfixExp); //计算后缀表达式的值并输出 int result = evaluatePostfix(postfixExp); printf("计算结果为:%d\n", result); return 0; ``` 这个简易计算器的实现基于栈的数据结构。它首先将用户输入的中缀表达式转换为后缀表达式,然后计算...
