pascal编程题

一道简单的Pascal编程题：编程由键盘输入的两个整数a，b，计算出他们的和并输在屏幕上

var

a,b:integer;

begin

readln(a,b);

writlen('a+b=',a+b);

readln;

end;

program plus;

var a,b:longint;

begin

readln(a,b);

writeln(a+b);

end.

program asdf; var a,b:longint;

begin writeln('please write a,b');

readln(a,b);

writeln(a,'+',b,'=',a+b);

readln;{让结果可以直接观察｝ end.

我可以给你个程序；

Program huida;

Var a,b:integer; //定义数据结构

Begin //主程序开始

writeln('a=?'); //输出‘a=？’

readln(a); //输入a

writeln('b=?'); //输出‘b=？’

readln(b); //输入b

s:=a+b; //求和

writeln('和为',s); //输出结果

End.

program addnum; var a:int;

b:int; begin write('a=?');

readln(a); write('b=?');

readln(b); writeln(a+b); end.
