Primul ex:
-------------------------------------------
#include <iostream>
using namespace std;
int a,b;
int main(){
cin>>a;
cout<<a/10<<","<<a%10;
b=(a%10)*10+a/10;
cout<<b;
}
-----------------------------------------
Al doilea:
#include <iostream>
using namespace std;
int a,b,c;
int main(){
cin>>a;
cin>>b;
cin>>c;
cout<<a<<b<<c<<"\n";
cout<<a<<c<<b<<"\n";
cout<<b<<a<<c<<"\n";
cout<<b<<c<<a<<"\n";
cout<<c<<a<<b<<"\n";
}
--------------------------------------------
Al treilea:
#include <iostream>
using namespace std;
int a;
int main(){
cin>>a;
cout<<2*a<<","<<3*a<<","<<4*a<<","<<5*a<<","<<6*a;
}
--------------------------------------------
Al patrulea:
#include <iostream>
using namespace std;
int a;
int main(){
cin>>a;
cout<<a-111;
}
--------------------------------------
Ultima:
#include <iostream>
using namespace std;
int a,b,c;
int main(){
cin>>a;
b=a/10;
b=b%10;
c=a%10;
cout<<b<<","<<c<<","<<b+c<<","<<b*c;
}
Cu placere :)
