C program to generate Double pyramid number pattern

C program to generate Double pyramid number pattern

In this tutorial, we will discuss a simple concept of the C program to generate Double pyramid number pattern

In this post, we will learn how to create double(Integrated) pyramid number pattern.

We can use for loop, while loop or do while loop to display different integrated pyramid number patterns.

 

Here we will use for loop to print different integrated pyramid number patterns

Program 1

Generate Integrated pyramid number pattern 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int rows,i,j;
    printf("Enter the number of rows: ");
    scanf("%d",&rows);
    for(i=1; i<=rows; i++){    //print upper part
    for(j=i; j<=rows; j++){
      printf("%d",j);//print number to upper part
}
printf("\n");//move to next line
}

for(i=rows-1; i>=1; i--){  //print lower part
    for(j=i; j<=rows; j++){
      printf("%d",j);//print number
}
printf("\n");//move to next line
        }
        getch();
    return 0;
}

When the above code is executed, it produces the following result

Enter the number of rows: 6
123456
23456
3456
456
56
6
56
456
3456
23456
123456

 

Program 2

Generate Integrated pyramid number pattern 2

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int rows,i,j;
    printf("Enter the number of rows: ");
    scanf("%d",&rows);
    for(i=rows; i>=0; i--){    //print upper part
    for(j=1; j<=i; j++){
      printf("%d",j);//print number
      printf(" ");
}
printf("\n");//move to next line
}
for(i=1; i<=rows; i++){  //print lower part
    for(j=1; j<=i; j++){
      printf("%d",j);//print number to lower part
      printf(" ");
}
printf("\n");//move to next line
        }
    return 0;
}

When the above code is executed, it produces the following result

Enter the number of rows
6
1 2 3 4 5 6 
1 2 3 4 5 
1 2 3 4 
1 2 3
1 2
1
1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4 5 6

 

 

Program 3

Generate Integrated pyramid number pattern 3

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int rows,i,j,k;
    printf("Enter the number of rows\n");
    scanf("%d",&rows);
    for(i=1; i<=rows; i++){    //print upper part
    for(j=1; j<=i; j++){
      printf(" ");//print space
}
for(k=i; k<=rows; k++){
      printf(k);//print number
      printf(" ");
}
printf("\n");
}

for(i=rows-1; i>=1; i--){  //print lower part
    for(j=1; j<=i; j++){
      printf(" ");
}
for(k=i; k<=rows; k++){
      printf(k);//print number
      printf(" ");
}
printf("\n");

}
getch();
return 0;
}

 

When the above code is executed, it produces the following result

Enter the number of rows: 6
1   2   3   4   5   6
  2   3   4   5   6
    3   4   5   6
      4   5   6
        5   6
          6
        5   6
      4   5   6
    3   4   5   6
  2   3   4   5   6
1   2   3   4   5   6

 

Program 4

Generate Integrated pyramid number pattern 4

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int rows,i,j;
    printf("Enter the number of rows: ");
    scanf("%d",&rows);
    for(i=1; i<=rows; i++){    //print upper part
    for(j=1; j<i; j++){
      printf(" ");//print space
}
for(j=i; j<=rows; j++){
      printf("%d",j);//print number to upper part
}
printf("\n");
}

for(i=rows-1; i>=1; i--){
  for(j=1; j<i; j++){
      printf(" ");//print space

for(j=i; j<=rows; j++){  //print lower part
      printf("%d",j);//print number to lower part
}
printf("\n");
        }
    return 0;
}

int main()
{
    int rows,i,j,k;
    printf("Enter the number of rows: ");
    scanf("%d",&rows);
    for(i=1; i<=rows; i++){    //print upper part
    for(j=1; j<=rows-i; j++){
      printf(" ");//print space
}
for(k=1; k<=i; k++){
      printf("%d",k);//print number to upper part
      printf(" ");

for(i=1; i<=rows-1; i++){  //print lower part
    for(j=1; j<=i; j++){
      printf(" ");//print space

for(k=1; k<=rows-i; k++){
      printf("%d",k);//print number to lower part
      printf(" ");
}
printf("\n");//move to next line
        }
    return 0;
}

 

When the above code is executed, it produces the following result

Enter the number of rows: 6
