PHP Exercises: Print the values of x, y where a, b, c, d, e and f are specified
PHP: Exercise-49 with Solution
Write a PHP program which solve the equation:
ax+by=c
dx+ey=f
Print the values of x, y where a, b, c, d, e and f are given.
Input:
a,b,c,d,e,f separated by a single space.
(-1,000 ≤ a,b,c,d,e,f ≤ 1,000)
Sample Solution:
PHP Code:
<?php
// Function to convert an input to a float
function to_f($e) {
return (float)$e;
}
// Read input from standard input (STDIN) line by line
while ($line = fgets(STDIN)) {
// Explode the line into an array using space as the delimiter
$a = explode(" ", $line);
// Convert each element of the array to a float using the "to_f" function
$a = array_map("to_f", $a);
// Calculate the values of x and y using the provided formulas
$x = ($a[2] * $a[4] - $a[1] * $a[5]) / ($a[0] * $a[4] - $a[3] * $a[1]);
$y = ($a[2] * $a[3] - $a[0] * $a[5]) / ($a[1] * $a[3] - $a[0] * $a[4]);
// Print the values of x and y with three decimal places
print("Values of x and y:\n");
printf("%.3f %.3f\n", $x, $y);
}
?>
Sample Output:
Values of x and y: -1.684 2.737
