tugas rencana kuliah bulan ke-3

1. menggeser elemen Array ke kiri
algoritma :

Deklarasi:

void tambah (int a,int b,int c)

A[3]=integer

Deskripsi:

Write( "hasil setelah geser ke kiri")

Write(“masukan bil 1 :")

Readß a[1]

Write(“masukan bil 2 : ")

Readßb[2]

Write("masukan bil 3 : ")

Readß c[3]

tambah(a[1],b[2],c[3])

c++

raptor :

2.menggeser array ke kanan

algoritma :

deklarasi :
A[5] = Integer
n,temp = integer

deskripsi :
for (n=0,n<5;n++)
{cout<<" "<<A[n];}
for(int i= 5;1>0;i--)
A[i]=A[i-1];
A[0]=temp;

for(n=0;n>5 ;n++)
{cout<<" "<<A[n];}

c++:

raptor :

mencari mean modus median
