Explain Program

Step :1

Header File

#include <stdio.h>

•  Standard I/O library to use the printf function for output.

Step :2

.Main Function

int main()

entry point of any C program. Execution starts 

Step :3

Variable Declarations

int n = 7; // Height of the J pattern

• a and b: Loop counters.

• n = 7: The size of the square grid (7 rows × 7 columns). 

Step :4

Outer Loop – Row

for (a = 0; a < n; a++)

• Control the rows from a = 0 to a = 6 (7 rows in total).

Each loop iteration correspond to one line of output

Step :5

 Inner Loop – Columns

for (b = 0; b < n; b++)

• Control the columns from b = 0 to b = 6 

• Prints either a * or a space " " for each cell.

Step :6

Main Logic – if Condition

if (b == n / 2 && a != 0 ||

    (a == n - 1 && b <= n / 2) ||

    (a == n - 2 && b == 0))

    printf("*");

else

    printf(" ");

analyze each part of this condition

Step :7

 Condition 1:

b == n / 2 && a != 0

• n / 2 = 7 / 2 = 3 (integer division).

• This checks:

• Column 3 (b == 3)

• For all rows except the first (a != 0)

 Draws the vertical bar of ‘J’, starting from row 1 down to 6 at the center.

Step :8

Condition 2:

a == n - 1 && b <= n / 2

• a == 6 (bottom row)
• b <= 3 → columns 0, 1, 2, 3

 bottom horizontal line of 'J'.

Step :9

Condition 3:

a == n - 2 && b == 0

• a == 5 (second-last row)
• b == 0 → first column

Add a small hook at the bottom left (curve of ‘J’)

Step :10

7. Line Break

printf("\n");

• After finishing each row (b loop ends), moves to a new line for the next row 

. Return Statement

return 0;

This C Program Print a pattern in the shape of the capital letter H using asterisks (*) 

Explain Program

Step :1

#include <stdio.h>

• standard input-output library use functions like printf().

Step :2

int main()

• The entry point of any C program.

Returns an integer 

Step :3

int a, b;

• These are loop variables used in the nested for loops:

• a: Controls the rows.

• b: Controls the columns.

Step :4

int n = 7;

• n is the dimension of the pattern.

• The output will be a 7x7 grid 

• You can modify n to change.

Step :5

for (a = 0; a < n; a++)

• Outer loop — iterates over rows from 0 to 6 (7 iterations).

Step :6

for (b = 0; b < n; b++)

• Inner loop — iterates over column from 0 to 6.

Step :7

if (b == 0 || b == n - 1 || a == n / 2)

key condition to print the star *:

• b == 0 → First column (left vertical line)

• b == n - 1 → Last column (right vertical line)

• a == n / 2 → Middle row (horizontal bar)

Step :8

printf("*");

 printf(" ");

• Prints either a star or a space.

Step :9

printf("\n");

• After each row is complete, this move to the next line.

Step :10

return 0;

Explain Program

Step :1

#include <stdio.h>

Includes the standard input-output library to use functions like printf().

Step :2

Step :4

int n = 7;

 dimension of the pattern is 7 × 7.

Step :5

Outer Loops

• loops iterates over each column in the current row, again from b = 0 to b = 6.

Step :7

Conditional Logic Inside Inner Loop:

         if (a == 0)

          printf("*");

• Top horizontal line: For the first row (a == 0), print * in all columns, making the top border of the pattern.

Step :8

else if (a == rows / 2 && b < rows - 2)

           printf("*");

• Middle horizontal line:

• When a == rows / 2 → a == 3 (since rows = 7, rows / 2 = 3 using integer division).

• This prints * from b = 0 to b = 4 (i.e., 5 stars), because b < rows - 2 → b < 5.

• row 4 (index 3) gets 5 stars.

Step :9

else if (b == 0)

            printf("*");

• Left vertical line: In all other rows, print * in the first column (b == 0).

Step :10

        else

            printf(" ");

• positions print a space ' ', creating the shape of the letter E.

Step :11

        printf("\n");

• Moves the output to the next line after each row is completed.

 Start of the main function where the execution begin

Step :3

    int a, b;

    int height = 7;

a and b are loop counters.

 height and width define the size of the pattern.

 height = 7: Number of rows.

 width = 5: Number of columns.

 Step :4

outer loop run  a = 0 to a = 6 (7 iterations), controlling the rows

Step :5

                printf("*");

            else

                printf(" ");

This condition determines where to print * or a space.

 Step :7

b == 0

prints a vertical line of * in the first column — like the vertical bar of "E".

 a == 0

Top row — prints the top horizontal line.

  a == height / 2

Middle row — prints the middle horizontal line.

  a == height - 1

Bottom row — prints the bottom horizontal line.
