Pattern In C Programming | C Program To Print Simple Pattern

In this program, we are going to make pattern in c programming using loops. It gives us a better understanding of the implementation of loops.

Pre-requisite: For/While loop

Half Pyramid Pattern in C

In this program, we will print half pyramid of numbers.

1
1 2
1 2 3
1 2 3 4

In the above pattern. we can observe that there are four rows and ith row has i columns. We will use 2 loops, the outer loop will iterate through rows and the inner loop will print numbers. It is also known as the triangular pattern in c.

#include <stdio.h>

int main() {
    
    int i=1;
    while(i<=4)
    {
        int j=1;
        while(j<=i){
            printf("%d ",j);
            j++;
        }
        
        printf("\n");
        i++;
        
    }
    
    return 0;
}

Right Triangle Star Pattern in C

In this program, we have to just print star "*" at the place of numbers.

Pattern Program in C using for loop

#include <stdio.h>

int main() {
    
    int n=4;
    int i=1;
    
    for(int i=1;i<=n;i++)
    {
       for(int j=1;j<=i;j++)
       printf("* ");
       printf("\n");
    }
    
    return 0;
}

Square Pattern Program in c using while loop

In this program, we will print a square pattern in c using while loop. We will run two loops as usual one for rows and another one is to print star in columns.

#include <stdio.h>

int main() {
    
    int n=4;
    int i=1;
    while(i<=n)
    {
        int j=1;
        while(j<=n){
            printf("* ");
            j++;
        }
        
        printf("\n");
        i++;
        
    }
    
    return 0;
}

C program to print alphabet pattern

This program is similar to a triangular pattern of numbers. In this example, we will print characters instead of numbers.

a
a b
a b c
a b c d

#include <stdio.h>

int main() {
    
    int n=4;
    int i=1;
    
    while(i<=n)
    {
        int j=1;
        char ch='a';
        while(j<=i){
            printf("%c ",ch);
            ch++;
            j++;
        }
        
        printf("\n");
        i++;
        
    }
    
    return 0;
}

Triangular Pattern in c

#include <stdio.h>
int main()
{
    int i, j;
    for (i = 1; i <= 5; i++)
    {
        for (j = 1; j <= 9; j++)
        {
            if ((j <= 5 - i) || (j >= 5 + i))
            {
                printf(" ");
            }
            else
            {
                printf("*");
            }
        }
        printf("\n");
    }

Output:

      *
    ***
  *****

About This C Program To Print Simple Pattern:

In conclusion, we made different pattern in c programming using for loop and while loop. However, if you have doubt or need code for a different pattern let me know in the comment section.  These programs give us a better clarity of loops, iterating through rows and columns.
