Pascal Triangle program in C++ language

Pascal Triangle program in C++ language

In this tutorial, we will discuss the concept of Pascal Triangle program in C++ language

In this topic, we are going to learn how to write a program to print Pascal triangle pattern using number in C++ programming language

Here, we use for, while and do-while loops for printing pascal triangle

Display pascal pattern in C++ using loops

C++ Code display triangle using for loop

In this program, the user is asked to enter number of rows and then it will display triangle number pattern using for loop in C++ language

Program 1

#include 
#include 
using namespace std;

int main()
{
    int rows,i,j,space,counter=1;
 cout<<"Enter the No of rows: ";
 cin>>rows;
//input rows for print pascal triangle
 for( i=0; i
When the above code is executed, it produces the following result

 
 
C++ Code display triangle using while loop
In this program, the user is asked to enter the number of rows and then it will display a triangle number pattern using the while loop in the C++ language
Program 2


#include 
#include 
using namespace std;

int main()
{
    int rows,i,j,space,counter=1;
 cout<<"Enter the No of rows: ";
 cin>>rows;
//input number of rows for print pascal triangle
 i=0;
 while(i
When the above code is executed, it produces the following result

 
C++ Code displays triangle using a do-while loop
In this program, the user is asked to enter a number of rows and then it will display a triangle number pattern using the do-while loop in C++ language
Program 3


#include 
#include 
using namespace std;

int main()
{
    int rows,i,j,space,counter=1;
 cout<<"Enter the No of rows: ";
 cin>>rows;//input number of rows for print pascal triangle
 i=0;
 do{//outer do while loop
        space=1;
   do{//inner do-while loop
   cout<<" ";
   space++;
   }while( space<=rows-i );
j=0;
  do{//inner do-while loop
   if(j==0 || i==0)
    counter=1;
   else
     counter=counter*(i-j+1)/j;
     cout<
When the above code is executed, it produces the following result
