1. FOR

Contoh 1:

#include<iostream.h>

#include<stdio.h>

#include<conio.h>

main()

{ int i,a;

clrscr();

for(a=10;a>=1;--a)

cout<<" "<<a;

getch();

}

Hasil : 10 9 8 7 6 5 4 3 2 1

Contoh 2 :

#include<iostream.h>

#include<stdio.h>

#include<conio.h>

main()

{ int a;

clrscr();

for(a=1;a<=10;++a)

cout<<" "<<a;

getch();

}

Hasil : 1 2 3 4 5 6 7 8 9 10

Contoh 3 :

#include <stdio.h>

#include <conio.h>

#include <iostream.h>

main()

{

int x, y;

clrscr();

for(x = 1;x <= 5; ++x)

{

for(y = 1; y <= x; ++y)

cout<<" "<<y;

cout<<endl;

}

getch();

}

Hasil :

Contoh 4:

#include<iostream.h>

#include<stdio.h>

#include<iomanip>

#include<conio.h>

main()

{

int a;

clrscr();

for(a=1; 17>a;a++)

{ gotoxy(a,a);textcolor(a);

cprintf("\n warna ke-%d",a);

}

textcolor(4+BLINK);cprintf("Borland C++");

getche();
