这篇博客针对QtC桌面计算器源码编写代码代码整洁规则易读。 学习与应用推荐首选。 文章目录
一、所需工具软件
二、使用步骤
1. 引入库
2. 主要代码
3. 运行结果
三、在线协助 一、所需工具软件
1. VS, Qt
2. C 二、使用步骤
1.引入库
代码如下示例 #include QDebug
#include iostream
#include cmath
#include QChar
#include QDialog
#include QFile
2.主要代码
代码如下示例 void MainWindow::Calc_Suffix()
{for(int i0;iout.size();i){bool is_Num true;out[i].toDouble(is_Num);if(is_Num)//如果是数字直接入栈{s2.push(out[i].toDouble(is_Num));}else if(out[i]s||out[i]c||out[i]t||out[i]^){double xs2.pop();if(out[i]s)xsin(x);else if(out[i]c)xcos(x);else if(out[i]t)xtan(x);else if(out[i]l)xlog(x);else if(out[i]^){int yx;xs2.pop();int zx;for(int j1;jy;j)xx*z;}s2.push(x);}else if(out[i]||out[i]-||out[i]*||out[i]/)//如果是运算符弹栈两次并进行运算运算后结果入栈{double xs2.pop();double ys2.pop();if(out[i]){s2.push(yx);}else if(out[i]-){s2.push(y-x);}else if(out[i]*){s2.push(y*x);}else if(out[i]/){s2.push(y/x);}}}result s2.pop();qDebug()result;
