Print Hollow Inverted Pyramid pattern in C language

In this article, we will discuss the Print Hollow Inverted Pyramid pattern in C language

In this post, we will learn how to create the hollow inverted Pyramid star pattern using for, while and do-wile loop

Code to Pyramid pattern-using for loop

Program 1

This program allows the user to enter the number of rows and the symbol then the program displays a hollow inverted pyramid star pattern with a given symbol using for loop in C language

Program 1

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

int main()
{
    int i,j,rows;//declared variables
    char ch;
    printf("Enter number of rows\n");
    scanf("%d%c",&rows,&ch);
    //Takes number of rows from user
    printf("Enter the symbol\n");
    ch=getchar();
    //input symol for pattern
    for(i=1; i<=rows; i++){//to iterates each row
for(j=1; j<=i; j++){//Print space for Pyramid shape
printf(" "); //print space
}
for(j=1; j<=(rows*2-(2*i-1)); j++){//to print *
if(i==1 || j==1|| j==(rows*2-(2*i-1))){

 printf("%c",ch); //print star
  }
 else {
printf(" "); //print space
 }

}
printf("\n");
}
getch();
    return 0;
}

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

Code to Pyramid pattern-using while loop

Program 2

This program allows the user to enter the number of rows and the symbol then the program displays a hollow inverted pyramid star pattern with a given symbol using while loop in C language

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

int main()
{
    int i,j,rows;//declared variables
    char ch;
    printf("Enter number of rows\n");
    scanf("%d%c",&rows,&ch);
    //Takes number of rows from user
    printf("Enter the symbol\n");
    ch=getchar();
    //input symol for pattern
    i=1;
    while(i<=rows){//to iterates each row
            j=1;
while(j<=i){//Print space for Pyramid shape
printf(" "); //print space
 j++;
}
j=1;
while( j<=(rows*2-(2*i-1))){//to print *
if(i==1 || j==1|| j==(rows*2-(2*i-1))){

 printf("%c",ch); //print star
  }
 else {
printf(" "); //print space
 }
 j++;
}
printf("\n");
 i++;
}
getch();
    return 0;
}

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

Code to Pyramid pattern-using do-while loop

Program 3

This program allows the user to enter the number of rows and the symbol then the program displays a hollow inverted pyramid star pattern with a given symbol using the do-while loop in C language

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

int main()
{
    int i,j,rows;//declared variables
    char ch;
    printf("Enter number of rows\n");
    scanf("%d%c",&rows,&ch);
    //Takes number of rows from user
    printf("Enter the symbol\n");
    ch=getchar();
    //input symol for pattern
    i=1;
    do{//to iterates each row
            j=1;
do{//Print space for Pyramid shape
printf(" "); //print space
 j++;
}while(j<=i);
j=1;
do{//to print *
if(i==1 || j==1|| j==(rows*2-(2*i-1))){

 printf("%c",ch); //print star
  }
 else {
printf(" "); //print space
 }
 j++;
}while( j<=(rows*2-(2*i-1)));
printf("\n");
 i++;
}while(i<=rows);
getch();
    return 0;
}
