这两个c程序加法器有什么区别 这是面向过程语言的程序模块化的思想，把一个功能分成一个个的模块（函数）假如这里面不仅是加法，而是加减乘除四种分别都做的话你要写四个的MAIN函数includeint a，b，c；main(){printf(\"please input value of a and b：\\n\")；scanf(\"%d%d\"，&a，&b)；printf(\"%d\\n\"，c，c=a+b)；}而如果分成一个个的模块，只要写一个MAIN函数，调用四个模块，封装的思想，使代码不重复，
java加法器的程序，帮忙看看 我给你做了一个，你看看对你有没有点帮助吧~import java.awt.*；import java.awt.event.*；public class Adder implements ActionListener{private Frame f；private Panel p1，p2；private Label la1，la2，la3；private Button b1，b2，b3，b4；private TextField t1，t2，t3；public Adder(){f=new Frame(\"计算器\")；p1=new Panel()；p2=new Panel()；la1=new Label(\"左数\")；la2=new Label(\"右数\")；la3=new Label(\"结果\")；t1=new TextField()；t2=new TextField()；t3=new TextField()；b1=new Button(\"+\")；b2=new Button(\"-\")；b3=new Button(\"*\")；b4=new Button(\"/\")；f.setLayout(new FlowLayout(FlowLayout.LEFT))；f.setLayout(new GridLayout(2，1))；p1.setLayout(new GridLayout(3，2))；p2.setLayout(new GridLayout(1，4))；p1.add(la1)；p1.add(t1)；p1.add(la2)；p1.add(t2)；p1.add(la3)；p1.add(t3)；p2.add(b1)；p2.add(b2)；p2.add(b3)；p2.add(b4)；f.add(p1)；f.add(p2)；b1.addActionListener(new ActionListener(){public void actionPerformed(ActionEvent e){double a1=Double.parseDouble(t1.getText())；double a2=Double.parseDouble(t2.getText())；t3.setText(String.valueOf(a1+a2))；}。
求高手看看我的程序问题，出在哪，一个简单加法器 #includesbit key1=P3^0；sbit key2=P3^1；sbit key3=P3^2；sbit key4=P3^3；main(){P1=0xff；while(1){if(key1){while(key1)；P1=0xfe；}else if(key2){while(key2)；P1=0xfd；}else if(key3){while(key3)；P1=0xfb；}else if(key4){while(key4)；P1=0xf7；}}}
