Patterns using C Programming

 There are many different patterns that can be printed using C programming. Here are a few examples:

1. Right-angle triangle

C

#include <stdio.h>

int main() {
  int n;
  printf("Enter the number of rows: ");
  scanf("%d", &n);

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

  return 0;
}

Output:

Code snippet

Enter the number of rows: 5

2. Inverted right-angle triangle

C

#include <stdio.h>

int main() {
  int n;
  printf("Enter the number of rows: ");
  scanf("%d", &n);

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

  return 0;
}

Output:

Code snippet

Enter the number of rows: 5

3. Arrow-shaped pattern

C

#include <stdio.h>

int main() {
  int n;
  printf("Enter the number of rows: ");
  scanf("%d", &n);

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

  for (int i = n - 1; i >= 0; i--) {
    for (int j = 0; j < n - i - 1; j++) {
      printf(" ");
    }
    for (int j = 0; j <= i; j++) {
      printf("* ");
    }
    printf("\n");
  }

  return 0;
}

Output:

Code snippet

Enter the number of rows: 5

These are just a few examples of the many patterns that can be printed using C programming. You can experiment with different patterns and see what you can create.
