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
#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
#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
#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
#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;
}
When the above code is executed, it produces the following result
Enter the number of roes: 6
123456
23456
3456
456
56
6
56
456
3456
23456
123456
Program 5
#include <stdio.h>
#include <stdlib.h>
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(" ");
}
printf("\n");
}
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
