Pattern Programs in C

Here in this article, we will cover the top example programs in C. Also, the rationale is all-inclusive and can be applied to various programming dialects, like C++, Java, and Python.

Pattern in C

List of pattern programs in c:

1. Solid Rectangular Star Pattern in C

rows: 3

columns: 5

* * * * *
* * * * *

Program

#include <stdio.h>

int main()
{

int rows, columns,i,j;
printf("Enter the number of rows : ");
scanf("%d", &rows);
printf("Enter the number of columns : ");
scanf("%d", &columns);

printf("\n");

/* print solid rectangle*/

for (i = 1; i <= rows; i++)
{
      for (j = 1; j <= columns; j++)
       {
             printf("*");
       }
      printf("\n");
}
return 0;
}

Output

Enter the number of rows : 3
Enter the number of columns : 5

Program

int main()
{
int rows, columns,i, j;
printf("Enter the number of rows : ");
scanf("%d", &rows);
printf("Enter the number of columns : ");
scanf("%d", &columns);
printf("\n");
/*Logic for holow rectangle*/
for (i = 1; i <= rows; i++)
{
	for (j = 1; j <= columns; j++)
	{	
    	if (i==1 || i==rows || j==1 || j==columns)
			printf("*");
		else
			printf(" ");
	}
	printf("\n");
}
return 0;
}

Output

Enter the number of rows : 4
Enter the number of columns : 5

Program

#include 
int main()
{
int stars,i, j;;
printf("Enter the number of stars : ");
scanf("%d", &stars);
/*Logic for half Pyramid*/
for (i = 1; i <= stars; i++)
{
	for (j = 1; j <= i; j++)
	{	
    	    printf("*");
	}
	printf("\n");
}
return 0;
}

Output

Enter the number of stars : 6

Program

int main()
{
int stars,i, j;;
printf("Enter the number of stars : ");
scanf("%d", &stars);

/*Logic for inverted Pyramid*/
for (i = stars; i >= 1; i--)
{
	for (j = 1 ; j <= i; j++)
	{	
         	printf("*");
	}
	printf("\n");
}
return 0;
}

Output

Enter the number of stars : 6

Program

#include <stdio.h>   
int main()  
{  
    int height,space,i,j,k;  
    printf("Enter the height of the triangle: ");  
    scanf("%d",&height);  
    space=height;  
   for( i=1;i<=height;i++)  
   {  
       for( j=1;j<space-1;j++)  
       {  
           printf(" ");  
       }  
       for( k=1;k<=2*i-1;k++)  
       {  
         printf("*");  
       }  
       space--;  
     
      printf("\n");  
    }  
    return 0;
