Write C Program to Print  Inverted Half Pyramid of Stars  Pattern

Example 

#include<stdio.h>
void main ()
{
int i,j,r;
printf("enter the number");

scanf("%d",&r);

for(i=r;i>=1;i--)

{
for(j=1;j<=i;j++)

}

printf("\n");

}

return 0;

}

Write C Program to Print  Inverted Half Pyramid of Stars  Pattern

Explain Program

Step :1

#include <stdio.h>

• standard input-output library, printf() and scanf() function

Step :2

void main()

• starting point of the program.

Step :3

. int i, j, r;

• Declares three integer variables:

• r: the number of rows (input from the user).

• i: used for the outer loop (rows).

• j: used for the inner loop (columns/asterisks per row).

Step :4

printf("enter the number");

scanf("%d", &r);

•  user to enter the number of rows for the triangle.

Step :5

for(i = r; i >= 1; i--)

• Starts at i = r and decrements to 1.

• First row has r stars,

• Second row has r-1 stars,

Step :6

for(j = 1; j <= i; j++)

{

    printf("*");

}

• row, prints i number of asterisks (*).

The number of asterisks decreases as i decreases

Step :7

printf("\n");

•  cursor to the next line after each row of asterisks.

Step :8

return 0;

C Program  Print Half Pyramid Using Numbers pattern

Explain Program

Step :1

#include<stdio.h>

• standard input-output header file use printf() and scanf().

Step :2

void main()

• main function  execution starts.

Step :3

 Variable Declarations

int i, j, r;

• r: Number of rows for the pattern (user input).

• i: Controls the outer loop (rows).
• j: Controls the inner loop (columns/numbers in each row).

Step :4

printf("enter the number");

scanf("%d", &r);

•  user to enter the number of rows.

Step :5

Outer Loop – Controls the Rows

for(i = 1; i <= r; i++)

• Starts 1 and goes up to r.

• Each iteration print one row of the triangle.

Step :6

for(j = 1; j <= i; j++)

{

    printf("%d", j);

}

•  each row i, it prints numbers from 1 to i.

Step :7

printf("\n");

cursor to the next line

Step :8

return 0;

c program for printing Right half pyramid pattern

Explain Program

Step :1

#include<stdio.h>

• Standard Input/Output library to use functions  printf() and scanf().

Step :2

int main() {

• main function where your program starts execution.

Step :3

int i, j, row;

• Declares three integer variables:

• i and j for loop counters.

• row to store the number of rows entered by the user.

Step :4

printf("enter the number of row");

•  user to enter how many rows they want in the pattern.

Step :5

 scanf("%d", &row);

•  input and stores it in the variable row.

Step :6

for (i = 1; i <= row; i++)

• Outer loop run from 1 .

Step :7

for (j = 1; j <= i; j++)

• Inner loop that run from 1 to i.

Step :8

printf ("%d", i);

• Print the current row number (i) in the same line.

Step :9

printf("\n");

• Moves the cursor  next line after printing one row of numbers.

Step :10

getch();

Write C Program to Print  Right Half Character Pyramid  Pattern 

Explain Program

Step :1

#include<stdio.h>

• standard input/output library.

•  use printf() and scanf() functions.

Step :2

int main()

• use starting point of your program.

Step :3

. int i, j, n;

• i – controls the row number

• j – controls to the numbers of characters printed per row

• n – stores the number of lines entered by the user

Step :4

printf("enter the no of line");

•  user to enter the number of lines to print.

Step :5

scanf("%d", &n);

• number of lines (rows) from the user and stores it in variable n.

Step :6

for(i = 1; i <= n; i++)

• Outer loop: runs from 1 to n
• Each iteration represents one row of the pattern.

Step :7

for(j = 1; j <= i; j++)

• Inner loop: runs from 1 to i

• It controls how many times a character is printed on each row.

Step :8

printf("%c", (char)(i + 64));

      This is the most interesting part!

•  printing a character, not a number.

Step :9

 printf("\n");

• After printing one row, move to the next line

 getch();

"C Program to Display a Star Square Pattern

Explain Program

Step :1

#include<stdio.h>

•  Standard Input Output library.

Step :2

int main()

• Entry point of the C program.

Step :3

int row, j, nacr();

• This line declares:

• int row:-> used as outer loop counter.

• int j:-> used as inner loop counter.

• nacr(); -> this  function named nacr that returns int and takes unknown parameters.

Step :4

for(row = 1; row <= 10; row++)

• Outer loop that runs from row = 1 to 10.

• Controls how many lines will be printed.

Step :5

for(j = 1; j <= 15; j++)

• Inner loop that prints asterisks on each line.

Step :6

printf("*");

• Prints one asterisk without a newline.

Step :7

printf("\n");

• After printing 15 stars, this moves the cursor to the next line.

Step :8
