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
Pattern 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
#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
#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
Pascal triangle pyramid pattern
#include <iostream>
#include <conio.h>
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;
}
When the above code is compiled and executed, it produces the following results
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1
1 6 15 20 15 6 1
Pattern 5
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int rows,i,j=0,num=0,count1=0,spaceCount;
cout<<"Enter the number of rows: \n";
cin>>rows;
for(i=1; i<=rows; i++){//outer for loop - parent
for(spaceCount=1; spaceCount<=rows-i; spaceCount++){
cout<<" ";//print space-inner for loop
count1++;
}
while(j!=2*i-1)
{
if(count1<=rows-1){
cout<<i+j;
num++;
}
else{
num++;
cout<<(i+j-2*num);
}
++j;
}
num=count1=j=0;
cout<<"\n";
}
getch();
return 0;
}
When the above code is compiled and executed, it produces the following results
Enter the number of rows:
4
1
2 3 4
3 4 5 6 7
4 5 6 7 8 9 10
Pattern 6
#include <iostream>
#include <conio.h>

}
++j;
}
num=count1=j=0;
cout<<"\n";
}

return 0;
}
When the above code is compiled and executed, it produces the following results
Enter the number of rows:
