C code to Generate Rhombus patterns using do-while loop
C code to Generate Rhombus patterns using do-while loop
In this article, we will discuss the concept ofC code to Generate Rhombus patterns using do-while loop
In this post, we are going to learn how to use do-while loop to write a program for print rhombus and hollow rhombus patterns using given symbol in C programming language.
#include
#include
//Program to print rhombus pattern using do-while loop
int main() {
int i,j,rows;//int variable declaration
char ch;//char variable declaration
printf("Enter the number of rows\n");
//ask input from the user for rows
scanf("%d%c",&rows,&ch);
//store the given input in the rows variable
printf("Enter the Symbol for pattern\n");
//ask input from the user for character
ch=getchar();
//store the given input in the ch variable
printf("\n");//move to next line
i=1;
do{//outer for loop
j=1;
do{//inner for loop
printf(" ");//print space
j++;
}while(j<=rows-i);
j=1;
do{//inner for loop
printf("%c",ch);//print character after space
j++;
}while(j<=rows);
printf("\n");//move to next line
i++;
}while(i
When the above code is executed, it produces the following result
Rhombus patterns
Code to print Hollow Rhombus pattern using do-while loop
Hollow Rhombus patterns
Program 2
This program allows the user to enter the number of rows and symbols then it will display the Hollow rhombus pattern using do-while loop in C programming language
#include
#include
int main()
{
int i,j,rows;
char ch;
printf("Enter the number of rows\n");
scanf("%d%c",&rows,&ch);
printf("Enter the Symbol for pattern\n");
ch=getchar();
printf("\n");
i=1;
do{//outer for loop
j=1;
do{
printf(" ");//print space
}while(j++<=rows-i);//inner for loop
if(i==1 || i==rows){
j=1;
do{
printf("%c",ch);//print symbol after space
}while(++j<=rows);
}
else{
j=1;
do{
if(j==1 || j==rows)
printf("%c",ch);//print char
else
printf(" ");//print space
}while(++j<=rows);
}
printf("\n");//move to next line
i++;
}while(i<=rows);
getch();
return 0;
}
When the above code is executed, it produces the following result
