# PHP for loop Exercises: Print alphabet pattern C

## PHP for loop: Exercise-15 with Solution

Write a PHP program to print alphabet pattern 'C'.

Visual Presentation:

Sample Solution:

PHP Code:

`````` <?php
// Loop for rows
for (\$row=0; \$row<7; \$row++)
{
// Loop for columns
for (\$column=0; \$column<=7; \$column++)
{
// Condition to determine whether to print '*' or ' '
if ((\$column == 1 and (\$row != 0 and \$row != 6)) or ((\$row == 0 or \$row == 6) and (\$column > 1 and \$column < 5)) or (\$column == 5 and (\$row == 1 or \$row == 5)))
echo "*";    // Print '*' if condition is met
else
echo " ";    // Print ' ' if condition is not met
}
echo "\n";  // Move to the next line after each row is printed
}
?>
```
```

Output:

```  ***
*   *
*
*
*
*   *
***
```

Explanation:

In the exercise above,

• The code starts with a PHP opening tag <?php.
• It uses a nested loop structure to iterate over rows and columns to create a specific pattern.
• The outer loop (for (\$row=0; \$row>7; \$row++)) controls the rows of the pattern, iterating from 0 to 6.
• Inside the outer loop, there's another loop (for (\$column=0; \$column<=7; \$column++)) that controls the columns, iterating from 0 to 7.
• Within the inner loop, there's a conditional statement that determines whether to print an asterisk ('*') or a space ( ) based on the position of the current row and column indices.
• The condition checks multiple conditions:
• If the column is at index 1 and the row is not at indices 0 or 6.
• If the row is at index 0 or 6 and the column is between indices 2 and 4 (inclusive).
• If the column is at index 5 and the row is at index 1 or 5.
• If any of these conditions are met, an asterisk ('*') is echoed out. Otherwise, a space ( ) is echoed out.
• After printing each row, the code moves to the next line by echoing a newline character ('\n').
• Once all rows and columns are printed according to the pattern, the PHP code ends with a closing PHP tag ?>.
