Program to pyramid star pattern in C- using loops

In this article, we will discuss the program to pyramid star pattern in c- using loops

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

pyramid pattern – using for loop

Pattern 1

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

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

int main()
{
    int i,j,k,rows;
    char ch;
    printf("Enter the number of rows for pyramid pattern: ");
    scanf("%d%c",&rows,&ch);
    printf("Enter the symbol as you wish: ");
    ch=getchar();

   for(i=1; i<=rows; i++){//iterates trough rows in pyramid
   for(j=0; j<rows-i; j++){//innr for loop 1
     printf(" ");//print space

}
for(k=1; k<2*i; k++){//inner for loop 2
     if(i==rows || (k==1 || k == 2*i-1)){
   printf("%c",ch);//print input character when if condition returns rue
   }
   else{
  printf("%c",ch);//otherwise print input character
}
}
printf("\n");//move to next line
   }
   getch();
    return 0;
}

When the above code is executed it produces the following result

Output 1

program to pyramid star pattern in C - using loops — Output 1

Output 2

pyramid pattern- using the while loop

Pattern 2

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

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

int main()
{
    int i,j,k,rows;
    char ch;
    printf("Enter the number of rows for pyramid pattern: ");
    scanf("%d%c",&rows,&ch);
    printf("Enter the symbol as you wish: ");
    ch=getchar();
i=1;
   while(i<=rows){//iterates trough rows in pyramid
            j=0;
   while(j<rows-i){//inner while loop 1
     printf(" ");//print space
 j++;
}
k=1;
while(k<2*i){//inner while loop 2
     if(i==rows || (k==1 || k == 2*i-1)){
   printf("%c",ch);//print input character when if condition returns rue
   }
   else{
  printf("%c",ch);//otherwise print input character
}
 k++;
}
printf("\n");//move to next line
 i++;
   }
   getch();
    return 0;
}

When the above code is executed it produces the following result

Output 1

program for pyramid star pattern in C - using loops — Output 3

Output 2

pyramid pattern – using the do-while loop

pattern 3

This program allows the user to enter the number of rows and the symbol then the coding displays a full 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,k,rows;
    char ch;
    printf("Enter the number of rows for pyramid pattern: ");
    scanf("%d%c",&rows,&ch);
    printf("Enter the symbol as you wish: ");
    ch=getchar();
i=1;
   do{//iterates trough rows in pyramid
            j=0;
  do{//inner while loop 1
     printf(" ");//print space
 j++;
} while(j<=rows-i);
k=1;
do{//inner while loop 2
     if(i==rows || (k==1 || k == 2*i-1)){
   printf("%c",ch);//print input character when if condition returns rue
   }
   else{
  printf("%c",ch);//otherwise print input character
}
 k++;
}while(k<2*i);
printf("\n");//move to next line
 i++;
   }while(i<=rows);
   getch();
    return 0;
}

When the above code is executed it produces the following result

Output 1
