文言文

由【键盘】入之甲、乙二整形元素。
以操作符【+】计算甲、乙之和。
存入另一整形元素丙。书之。

伪代码（PQ）

set keyboard as stdin
set screen as stdout
input int1024 a b
c=a(operator +)b
output c as int1024

伪代码(XD20)
这个在XD22中也可运行

function main
begin.
stdin a
stdin b
stdout a+b
end.

伪代码（XD22）

select keyboard as stdin
select screen as stdout
gnu -O2 -Wall
function main
begin.
stdin a
stdin b
stdout a+b
end.

伪代码（Z）

select keyboard as input
select screen as output
select windows11 as system
select Z22 as language
select ZS22 as compiler
begin.
read a
read b
write a+b
end.
flush.

Pascal

var a, b: longint;
begin
    readln(a,b);
    writeln(a+b);
end.

C++

#include<bits/stdc++.h>
using namespace std;
int fu=1,f=1,a,b,c=0;
int main(){
    cin>>a>>b;
    if(a<0&&b>0)fu=2;
    if(a>0&&b<0)fu=3;
    if(a<0&&b<0)f=-1;
    if(a==0){cout<<b;return 0;}
    if(b==0){cout<<a;return 0;} 
    a=abs(a);
    b=abs(b);
    if(a>b&&fu==3)f=1;
    if(b>a&&fu==3)f=-1;
    if(b>a&&fu==2)f=1;
    if(b<a&&fu==2)f=-1;
    if(fu==1)c=a+b;
    if(fu>1)c=max(a,b)-min(a,b);
    c*=f;
    cout<<c;
    return 0;
