#include<iostream.h> #include<conio.h> void main() { clrscr(); int i, j; for(i=0; i<5; i++) { for(j=5; j>i; j--) { cout<<"* "; } cout<<"\n"; } getch(); }

When the above C++ program is compile and executed, it will produce the following output (inverted half pyramid using stars):


This C++ program prints the inverted half pyramid using numbers.

#include<iostream.h> #include<conio.h> void main() { clrscr(); int i, j, num=1; for(i=0; i<5; i++) { for(j=5; j>i; j--) { cout<<num<<" "; num++; } cout<<"\n"; num=1; } getch(); }

When the above C++ program is compile and run, it will produce the following output (inverted half pyramid using numbers):


/* C++ Pattern Program of Numbers */ #include<iostream.h> #include<conio.h> void main() { clrscr();

int i, j, num=1, incr=1; for(i=0; i<5; i++) { for(j=0; j<incr; j++) { cout<<num++<<" "; /* in the above statement * first num printed their * previous value, then * incremented by 1 */ } cout<<"\n"; incr=incr+2; } getch(); }

The sample run of this C++ program is :

C++ Pattern Program No. 13

/* This C++ program prints pattern of numbers */ #include<iostream.h> #include<conio.h> void main() { clrscr(); int i, j, k, num=1, decr=8, count=0, temp; for(i=0; i<5; i++) { // this loop is to print spaces for(k=0; k<decr; k++) { cout<<" "; } // this loop is to give the required value to num for(j=0; j<i; j++) { count++; } num = count; temp = num; // this loop is to print the numbers for(j=0; j<i; j++) { cout<<num--<<" "; /* from the above statement,

* num is first printed, then * decremented by 1 */ } cout<<"\n"; num = temp; decr=decr-2; } getch(); }

Here is the sample run of the above C++ program:


/* This C++ program prints the alphabet * patterns on the screen */ #include<iostream.h> #include<conio.h> void main() { clrscr(); int i, j, incr=1; char ch = 'A'; for(i=0; i<5; i++) { for(j=0; j<incr; j++) { cout<<ch<<" "; ch++; } cout<<"\n"; incr = incr + 2; } getch(); }

Below is the sample run of this C++ program :


/* Now this C++ program also prints the * pattern of alphabet but in different * order */ #include<iostream.h> #include<conio.h> void main() { clrscr(); int i, j, k, decr=8, count=64, temp; char ch='A'; for(i=0; i<5; i++) { for(k=0; k<decr; k++) { cout<<" "; } for(j=0; j<i+1; j++) { count++; } ch = count; temp = ch; for(j=0; j<i+1; j++) { cout<<ch--<<" "; } cout<<"\n"; ch = temp; decr=decr-2; } getch(); }

Here sample run given of this C++ program:

40 Print Diamond Pattern in C++

To print diamond pattern of stars in C++ programming, you have to ask from the user to enter the number of rows (upto which he/she want to print the diamond patter) for dimension of diamond. Now to print diamond pattern of stars, use six for loops. The first for loop (outer for loop which contains two for loops. One to print spaces and the second to print stars) is to print pyramid pattern of stars. The second for loop (the second outer for loop which also contains

two for loops. One to print spaces and second to print stars) is used to print reverse pyramid of stars. Which wholly makes a diamond pattern of stars as shown here in the following program.

C++ Programming Code to Print Diamond Pattern

Following C++ program ask to the user to enter number of rows for diamond dimension to print the diamond pattern, then display the result on the screen:

/* C++ Program - Print Diamond Pattern */ #include<iostream.h> #include<conio.h> void main() { clrscr(); int n, c, k, space=1; cout<<"Enter number of rows (for diamond dimension) : "; cin>>n; space=n-1; for (k=1; k<=n; k++) { for(c=1; c<=space; c++) { cout<<" "; } space--; for(c=1; c<=(2*k-1); c++) { cout<<"*"; } cout<<"\n"; } space=1; for(k=1; k<=(n-1); k++) { for(c=1; c<=space; c++) { cout<<" "; } space++; for(c=1 ; c<=(2*(n-k)-1); c++) { cout<<" "; } cout<<"\n"; } getch(); }
