*Cách khác:
uses crt;
var a,b,c,d,max:integer;
begin
clrscr;
write('Nhap a='); readln(a);
write('Nhap b='); readln(b);
write('Nhap c='); readln(c);
write('Nhap d='); readln(d);
writeln('Tong cua 4 so la: ',a+b+c+d);
max:=a;
if max<b then max:=b;
if max<c then max:=c;
if max<d then max:=d;
writeln('Gia tri lon nhat la: ',max);
readln;
end.
#include <bits/stdc++.h>
using namespace std;
long long a,b,i,dem,s;
int main()
{
cin>>a>>b;
dem=0;
s=0;
for (i=a; i<=b; i++)
if (i%2==0)
{
dem++;
s=s+i;
}
cout<<dem<<" "<<s;
return 0;
}
#Include <bits/stdc++.h>
using namespace std;
int a,b,c;
int main()
{
cin>>a>>b>>c;
cout<<a+b+c<<endl;
cout<<a-b-c<<endl;
cout<<a*b*c;
return 0;
}
Bài 2:
#include <bits/stdc++.h>;
using namespace std;
int main();
{
long m,n;
cout<<"Nhap m="; cin>>m;
cout<<"Nhap n="; cin>>n;
cout<<m*n-2;
return 0;
}
