There are many pattern programs are written by programmers for practice purposes. The diamond pattern programs are one of them. Here we will write half diamond pattern in the C programming language.
C Program to Print Half Diamond Star Pattern
Write a C program to print the half diamond using stars. If the input n=5, the output is:-
*
**
***
****
*****
****
***
**
*
For input n, there are 2*n-1
rows. For row (say i) if i<n
then rows having i
stars, else it has -(2*n-i)
rows.
In the below program, the star variable holds the number of stars in the nth row. In every row, the star variable is updated. When i>n
then (2*n-i) will be negative so, the abs() function is used to find the absolute value of (2*n-i).
#include<stdio.h>
#include<stdlib.h>
int main()
{
int n, star;
printf("Enter number of rows: ");
scanf("%d",&n);
for(int i=1; i< 2*n; i++)
{
if(i < n) star=i;
else star = abs(2*n-i);
for(int j=1; j<=star; j++)
printf("*");
printf("\n"); //next line
}
return 0;
}
C Program to Print Mirrored Half Diamond Star Pattern
Write a C program to display mirrored half diamond using the stars. For input n=5 the output is,
*
**
***
****
*****
****
***
**
*
For input n there are 2*n-1
rows. In the ith row, there are n-i
(positive value) spaces, after that there are i
stars are present.
Program to display mirrored half diamond star pattern using the C programming language.
#include<stdio.h>
#include<stdlib.h>
int main()
{
int n;
printf("Enter number of rows: ");
scanf("%d",&n);
for(int i=1; i<= 2*n; i++)
{
for(int j=1; j<=n; j++)
if(j<= abs(n-i)) printf(" ");
else printf("*");
printf("\n"); //next line
}
return 0;
}
Half Diamond Pattern Programs Using Numbers
Write a C program to display the given below half diamond using numbers. For input n = 4 the output is,
1
2*2
3*3*3
4*4*4*4
3*3*3
2*2
1
For input n there are 2*n-1
rows are there. In ith row up to 2*i-1
places, on every even place, there is a star and on odd places the value of i is present.
#include<stdio.h>
#include<stdlib.h>
int main()
{
int n, place;
printf("Enter number of rows: ");
scanf("%d",&n);
for(int i=1; i< 2*n; i++)
{
if(i < n) place=i;
else place = abs(2*n-i);
for(int j=1; j< 2*place; j++)
if(j%2==0) printf("*"); //stars
else printf("%d",place); //numbers
printf("\n"); //next line
}
return 0;
}
Write a C program for the given below number pattern. The input n=5, the output is,
1
12
123
1234
12345
1234
123

Code for the above pattern,
#include<stdio.h>
#include<stdlib.h>
int main()
{
int n, place, a;
printf("Enter number of rows: ");
scanf("%d",&n);
for(int i=1; i< 2*n; i++)
{
a=1;
if(i < n) place=i;
else place = abs(2*n-i);
for(int j=1; j<=place; j++)
printf("%d",a++);
printf("\n"); //next line
}
return 0;
}
