CPP program to print Floyd’s triangle number patterns
In this tutorial, we will discuss about CPP program to print Floyd’s triangle number patterns
In C++ language, we can write different Floyd’s triangle number pattern program using nested for loop.
To understand this pattern, you must know how for loop and nested for loop works in C++ language
C++ floyd’s triangle number pattern programs
Number pattern 1
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int i,j,row;
cout<<"Enter the value for row :";
cin>>row;
cout << "The number floyd's triangle patterns" << endl;
for(i=1; i<=row; i++ ){
for(j=1; j<=i; j++ ){
cout<<i<<" ";
}
cout<< endl;
}
getch();
return 0;
}
When the above code is executed, it produces the following results:
Enter the value for the row: 8 The number Floyd's triangle pattern 1 22 333 4444 55555 666666 7777777 88888888
Number pattern 2
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int i,j,row;
cout<<"Enter the value for row :";
cin>>row;
cout << "The number floyd's triangle patterns" << endl;
for(i=1; i<=row; i++ ){
for(j=1; j<=i; j++ ){
cout<<j<<" ";
}
cout<< endl;
}
getch();
return 0;
}
When the above code is executed, it produces the following results:
Enter the value for the row: 7 The number Floyd's triangle pattern 1 12 123 1234 12345 123456 1234567
Number pattern 3
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int i,j,k=1,rows;
cout<<"Enter number of rows";
cin>>rows;
cout<<"You entered 8 \n here your triangle pattern\n";
for(i=1; i<=rows; i++){
for(j=1; j<=i; j++){
cout<<k<<" ";
k++;
}
cout<< endl;
}
getch();
return 0;
}
When the above code is executed, it produces the following results:
Enter number of rows: 8 you entered 8 here your triangle pattern 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36
Number pattern 4
inverted floyd’s triangle pattern printing using nested for loop
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int i,j,rows;
cout<<"Enter the number of rows you want :";
cin>>rows;
cout << "here your "<<rows << " number of rows floyd's triangle"<<endl;
for(i=rows; i>=1; i--){
for(j=1; j<=i; j++){
cout<<j<<" ";
}
cout<<endl;
}
getch();
return 0;
}
When the above code is executed, it produces the following results:
Enter number of rows you want: 8 here your 8 number of Floyd's triangle 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 1 2 3 4 5 6 1 2 3 4 5 1 2 3 4 1 2 3 1 2 1
Number pattern 5
floyd’s triangle pattern printing using for loop and while loop
#include <iostream>
using namespace std;
int main()
{
int rows,n;
cout<<"Enter the number of rows you want :";
cin>>rows;
cout << "Here number pattern is:" << endl;
for(int i=1; i<=rows; ++i)
{
n=rows-i;
while(n>0)
{
cout<<" ";
n--;
}
for(int j=i; j>=1; j--)
{
cout<<j;
}
cout<<"\n";
}
return 0;
}
When the above code is executed, it produces the following results:
1
21
321
4321
54321
654321
7654321
87654321
