Solution Approach
We will use the loops to solve the full pyramid of odd number patterns. The following steps have to be performed to obtain the pattern.
- Take an outer ‘for’ loop to print all the rows.
- Take two inner ‘for’ loops to print the first half of the spaces, and the second half to print the odd number.
- We can increment the odd number by 2 after every iteration of the row. We will initialize the number as 1.
Implementation in C
Here is the source code of the C program to print the full pyramid of odd number patterns.
#include <stdio.h>
int main() {
printf("Enter the row size:");
int row_size;
int num = 1;
scanf("%d",&row_size);
for(int j = 0; j < row_size; j++) {
for(int i = row_size - 1; i > j; i--) {
printf(" ");
}
for(int i = 0; i < num; i++) {
printf("%d",num);
}
num += 2;
printf("\n");
}
}

Implementation in C++
Here is the source code of the C++ program to print the full pyramid of odd number pattern.
#include <iostream>
using namespace std;
int main() {
printf("Enter the row size:");
int row_size;
int num = 1;
cin>>row_size;
for(int j = 0; j < row_size; j++) {
for(int i = row_size - 1; i > j; i--) {
cout<<" ";
}
for(int i = 0; i < num; i++) {
cout<<num;
}
num += 2;
cout<<"\n";
}
}

Implementation in Java
Here is the source code of the Java program to print the full pyramid of odd number pattern.
import java.util.Scanner;
public class CodingNinjas {
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter the row size:");
int num = 1;
int rowSize = sc.nextInt();
for(int j = 0; j < rowSize; j++) {
for(int i = rowSize - 1; i > j; i--) {
System.out.print(" ");
}
for(int i = 0; i < num; i++) {
System.out.print(num);
}
num += 2;
System.out.println();
}
}
}

Implementation in Python
Here is the source code of the Python program to print the full pyramid of odd number pattern.
print("Enter the row size: ")
num = 1
row_size = int(input())
for j in range(row_size):
i=row_size-1
while i>j:
print(" ", end="")
i=i-1
for i in range(num):
print(num, end="")
num=num+2
print()
