Program C++ Deret Bilangan

program C++ Deret Bilangan Ganjil dan GenapSOAL DAN JAWABAN 

Buatlah program untuk menghitung 10 deret bilangan genap dengan hasilnya :
2 + 4 + 6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 = 110



#include<iostream.h>
#include<conio.h>


main()
{
int a=2,b=20,n;

for(a=a;a<=b;a+=2)
{                          
cout<<a;
if(a<b)
{
cout<<" + ";
}
}

cout<<" = ";
n=b/2;
n=n*(n+1);
cout<<n;

   getch();

}



Buatlah program untuk menghitung 10 deret bilangan ganjil dengan hasilnya :
1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 = 100


#include<iostream.h>
#include<conio.h>


main()
{
int a=1,b=19,n;


for(a=a;a<=b;a+=2)
{
cout<<a;
if(a<b)
{
cout<<" + ";
}
}


cout<<" = ";
n=(b+1)/2;
n=n*n;
cout<<n;


   getch ();
}



Buatlah program untuk menghitung penjumlahan deret bilangan membentuk segitiga siku dengan hasilnya :
1 = 1
1 + 2 = 3
1 + 2 + 3 = 6
1 + 2 + 3 + 4 = 10
1 + 2 + 3 + 4 + 5 = 15


#include<iostream.h>
#include<conio.h>


main()
{
int A,i,j,jum;


for (i=1;i<=4;i++)
{
jum=0;
for (j=1;j<=i;j++)
{
if (j != 1)
cout<<"+";
cout<<j;
jum +=j;
}
cout<<"\t\t=  "<<jum<<endl;
}


for (i=5;i==5;i++)
{
jum=0;
for (j=1;j<=i;j++)
{
if (j != 1)
cout<<"+";
cout<<j;
jum +=j;
}
cout<<"\t=  "<<jum<<endl;
}


getch();
}

We've got an unbelievable wealth of franchises and content that we can create to put on places like Disney+ or in movie theaters. So, really, our strength in the past is our strength in the future. And that's what will drive us to that restoration of the magic. And so, I'm bullish about the future. I'm extremely bullish about the Walt Disney Company and its ability and its mission to create those magical memories that last a lifetime.
