In this tutorial, we will discuss a concept of C program to display integrated pyramid number pattern using while loop
In the C programming language, we can use for loop ,while loop and do-while loop to display different number (binary, decimal), alphabets or star pattern programs.
In this article, we are going to learn how to Display integrated pyramid number pattern using while loop in C language
Program 1
#include <stdio.h>
#include <stdlib.h>
int main()
{
int i,j,row;
printf("Enter the number of rows: ");
scanf("%d",&row);//Takes input fromt the user
printf("\n");//move to next line
i=1;
while(i<=row){
j=i;
while(j<=row){ //Print number
printf("%d",j);
j++;
}
i++;
printf("\n");
}
i=row-1;
while(i>=1){
j=i;
while(j<=row){
printf("%d",j); //Print number
j++;
}
i--;
printf("\n");
}
getch();
return 0;
}
When the above code is executed, it produces the following results
Program 2
#include <stdio.h>
#include <stdlib.h>
int main()
{
int i,j,row;
printf("Enter the number of rows: ");
scanf("%d",&row);//Takes input fromt the user
printf("\n");
i=1;
while(i<=row){//print upper part of shape
j=1;
while(j<i){
printf(" ");//print space
j++;
}
j=i;
while(j<=row){
printf("%d",j);//print number
j++;
}
i++;
printf("\n");//move to next line
}
i=row-1;
while(i>=1){//print lower part of shape
j=1;
while(j<i){
printf(" ");//print space
j++;
}
j=i;
while(j<=row){
printf("%d",j);//print number
j++;
}
i--;
printf("\n");
}
getch();
return 0;
}
When the above code is executed, it produces the following results
Program 3
#include <stdio.h>
#include <stdlib.h>
int main()
{
int i,j,row;
printf("Enter the number of rows: ");
scanf("%d",&row);//Takes input fromt the user
printf("\n");
i=1;
while(i<=row){
j=1;
while(j<=i){
printf(" ");
j++;
}
j=i;
while(j<=row){
printf("%d",j);//print number
printf(" ");//print space
j++;
}
i++;
printf("\n");//move to next line
}
i=row-1;
while(i>=1){
j=1;
while(j<=i){
printf(" ");//print space
j++;
}
j=i;
while(j<=row){
printf("%d",j);//print number
printf(" ");//print space
j++;
}
i--;
printf("\n");
}
getch();
return 0;
}
When the above code is executed, it produces the following results
Program 4
#include <stdio.h>
#include <stdlib.h>
int main()
{
int i,j,row;
printf("Enter the number of rows\n");
scanf("%d",&row);//Takes input fromt the user
printf("\n");
i=1;
while(i<=row){
j=1;
while(j<=row-i){
printf(" ");
j++;
}
j=1;
while(j<=i){
printf("%d",j);
printf(" ");
j++;
}
i++;
printf("\n");
}
i=1;
while(i<=row-1){
j=1;
while(j<=i){
printf(" ");
j++;
}
j=1;
while(j<=row-i){
printf("%d",j);
printf(" ");
j++;
}
i++;
printf("\n");
}
getch();
return 0;
}
When the above code is executed, it produces the following results
Program 5
include <stdio.h>
#include <stdlib.h>
int main()
{
int i,j,k,rows;
printf("Enter the number of rows\n");
scanf("%d",&rows);//Takes input fromt the user
printf("\n");
i=1;
while(i<=rows){
j=1;
while(j<=i){
printf("%d",j);
j++;
}
j=i*2;
while(j<rows*2){
printf(" ");
j++;
}
k=i;
while( k>=1){
printf("%d",k);
k--;
}
printf("\n");
i++;
}
getch();
return 0;
}

Program 6
#include <stdio.h>
#include <stdlib.h>
int main()
{
int i,j,k,rows;
printf("Enter the number of rows\n");
scanf("%d",&rows);//Takes input fromt the user
printf("\n");
i=rows;
while(i>=1){
j=1;
while(j<=i){
printf("%d",j);
j++;
}
j=i*2;
while( j<rows*2-1){
printf(" ");
j++;
}
k=i;;
while( k>=1){
if(k!=rows)
printf("%d",k);
k--;
}
printf("\n");
i--;
}
getch();
return 0;
}
When the above code is executed, it produces the following results
Program 7
#include <stdio.h>
#include <stdlib.h>
int main()
