Programs to Print Patterns in C or CPP ( Printing Patterns )

These are programs for printing various different patterns written in C language or C++ language.

These patterns are star patterns and some are character patterns.

Programs to Print Patterns in C or CPP ( Printing Patterns )

Note: The following programs can be used to print as big pattern as you want that is you can vary the inputs according to the requirement and print .

1.Print the pattern ( Language : C )

*
**
***
****
*****

#include <stdio.h>

 int main(void) {
 int n;
 printf("Enter no of rows :");
 scanf("%d",&n);
 for(int i=0;i<n;i++)
 {
 for(int j=0;j<=i;j++)
 {
 printf("*");
 }
 printf("\n");
 }
 return 0;
 }

2. Print the pattern ( Language : C )

#include <stdio.h>

int main()

{
int n;
printf("Enter no of rows :");
scanf("%d",&n);
for(int i=1;i<=n;i++)
{
 for(int j=1;j<=n;j++)
{
if (j<=n-i)
      {
         printf(" ");
      }
      else{
        printf("*");
      } 
    }
    printf("\n");
  }
  return 0;
}

      }
     else
     {
     printf(" ");
     }
    }
    printf("\n");
  }

      }
     else
     {
     printf(" ");
     }
    }
    printf("\n");
  }
  return 0;
