冷清啊。。我来一发Python3的题解

a, b = map(int, input().split())
print(a + b)

恩 就是这么简洁qwq

#include <iostream>
using namespace std;
int main()
{
    int a,b;
    cin>>a>>b;
    cout<<a+b;
    return 0;
}

#include <iostream>
using namespace std;
int main()
{
int a,b;
cin>>a>>b;
cout<<a+b;
return 0;
}

#include<iostream>
using namespace std;
int main()
{
int a,b,c;
cin>>a>>b;
c=a+b;
cout<<c<<endl;
return 0;
}

很简单

#include <cstdio>

    cout<<a+b<<endl;
    return 0;

int main (int argc, char* argv[]) {
      cin >> a >> b;
        cout << a+b << endl;
        return 0;'
    }

//读入优化

int read()
{
int x=0;char c;int f=1;
for(c=getchar();c<'0'||c>'9';c=getchar())if(c=='-')f=-1;

cout<<a+b<<endl;

#include <stdio.h>

{

scanf("%d%d",&a,&b);
printf("%d\n",a+b);
}

一道最基本的入门题，是基础，很简单
#include<cstdio>
#include<iostream>
using namespace std;
int main()
{
int n,m,k;
cin>>n>>m;
k=n+m;
cout<<k;
return 0;
}

#include<cstdio>
#include<cstdlib>
#include<cstring>
#include<iostream>
using namespace std;
int main(){
int a,b;
cin>>a>>b;
cout<<a+b;
return 0;
}

#include<cstdio>
#include<cstdlib>
#include<cstring>
#include<iostream>
using namespace std;
int main(){
int a,b;
cin>>a>>b;
cout<<a+b;
return 0;
}

#include<cstdio>
#include<cstdlib>
#include<cstring>
#include<iostream>
using namespace std;
int main(){
int a,b;
cin>>a>>b;
cout<<a+b;
return 0;
}

#include<iostream>
using namespace std;

int main()
{
    int a,b;
        cin>>a>>b;
        cout<<a+b;
        return 0;
}

好长时间才做出来
#include<cstdio>
#include<cstring>
#include<iostream>
using namespace std;
char a1[10000],b1[10000];int a[10000],b[10000],c[10000],x=0,lena,lenb,lenc=1,i;
int main()
{
scanf("%s",a1);scanf("%s",b1);lena=strlen(a1);lenb=strlen(b1);
for(i=0;i<=lena-1;i++) a[lena-i]=a1[i]-'0';
for(i=0;i<=lenb-1;i++) b[lenb-i]=b1[i]-'0';
while(lenc<=lena||lenc<=lenb)
{
c[lenc]=a[lenc]+b[lenc]+x;
x=c[lenc]/10;
c[lenc]%=10;
lenc++;
}
if(0==(c[lenc]=x)) lenc--;
for(i=lenc;i>=1;i--) cout<<c[i];return 0;
}

高精度的代码，其实是比较暴力的高精，但是因为它小于等于2^15-1，所以没什么关系。
我是通用性的高精度代码，所以数组开了10000.接下来就是——代码！

#include<cstdio>
#include<cstring>
#include<iostream>
using namespace std;
char a1[10000],b1[10000];int a[10000],b[10000],c[10000],x=0,lena,lenb,lenc=1,i;
int main()
{
scanf("%s",a1);scanf("%s",b1);lena=strlen(a1);lenb=strlen(b1);
for(i=0;i<=lena-1;i++) a[lena-i]=a1[i]-'0';
for(i=0;i<=lenb-1;i++) b[lenb-i]=b1[i]-'0';
while(lenc<=lena||lenc<=lenb)
{
c[lenc]=a[lenc]+b[lenc]+x;
x=c[lenc]/10;
c[lenc]%=10;
lenc++;
}
if(0==(c[lenc]=x)) lenc--;
for(i=lenc;i>=1;i--) cout<<c[i];return 0;
}
