Cpp program to pyramid number pattern

Cpp program to pyramid number pattern

In this tutorial, we will discuss the Cpp program to pyramid number pattern

In this topic, we will learn how to create number pattern in C++ language using for loop and while loop

pyramid number pattern programs in C++language

Pattern 1

Pyramid triangle number pattern program 1

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int i,j,k,rows;
    cout<<"Enter the rows: ";
    cin>>rows;//get input from user
    for(i=1; i<=rows; i++){
            for(j=1; j<=rows; j++){
        cout <<" ";//print space

    }
    for(k=1; k<=i; k++){
        cout <<i;//print number
        cout <<" ";//print space amon  g the numbers

    }
    cout<<"\n";//move to nesxt line
    rows=rows-1;//row value decrease by 1
    }
    getch();
    return 0;
}

When the above code is compiled and executed, it produces the following results

Enter the rows: 9
          1
        2   2
      3   3   3
    4   4   4   4
 5    5   5   5   5

 

Pattern 2

Pyramid triangle number pattern program 2

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int rows,i,j,k,l=1;
    cout<<"Enter the number of rows :";
    cin>>rows;//get user input from user
    cout<<"Here your pyramid pattern\n";
    for(i=1; i<=rows; i++){
        for(j=1; j<=rows-i; j++){//iterates for print space
        cout<<" ";//print space
    }
    for(k=1; k<=i; k++){
       cout<<k; //print number
       cout<<" ";//print space among the numnbers
    }
    cout<<"\n";
    k=k-1;
    }
    getch();
    return 0;
}

When the above code is compiled and executed, it produces the following results

Enter the number of rows :7
Here your pyramid pattern

                       1
                     1   2
                   1   2   3
                 1   2   3   4
              1    2   3   4   5
            1   2    3   4   5   6
          1   2    3   4   5   6   7

 

Pattern 3

Pyramid triangle number pattern program 3

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int rows,i,j,k,l=1;
    cout<<"Enter the number of rows :";
    cin>>rows;
    cout<<"Here your pyramid pattern\n";
    for(i=1; i<=rows; i++){
        for(j=1; j<=rows-i; j++){//iterates for space
        cout<<" ";//print initial space for pyramid shape
    }
    for(k=1; k<=i; k++,l++){
       cout<<l;//print numbers
       cout<<" ";//print space amongthe numbers
    }
    cout<<"\n";//move to next line
    }
    getch();
    return 0;
}

When the above code is compiled and executed, it produces the following results

Enter the number of rows: 4
Here your pyramid pattern

          1
       2    3
     4   5    6
   7   8   9    10

 

Pattern 4

Pyramid triangle number pattern program 4

Pascal triangle pyramid pattern

#include <iostream>

using namespace std;
int main()
{
    int rows,i,j,space_count,count1=1;
    cout<<"Enter the number of rows: \n";
    cin>>rows;
    for(i=0; i<=rows; i++){//outer for loop - parent
        for(space_count=1; space_count<=rows-i; space_count++){
                cout<<" ";//print space-inner for loop
    }
    for(j=0; j<=i; j++){
            if(j==0 || i==0)
            count1=1;
    else
            count1=count1*(i-j+1)/j;
            cout<<count1<<" ";
    }
    cout<<"\n";
    }
getch();
    return 0;
}

              1
            1   1
          1   2   1
        1   3   3   1
      1   4   6   4   1
