Writing a Program

Programming can either be Heaven or Hell depending on how much you know and how much you understand. As a CS student, majority of my course mates are still having hard time in programming. While browsing through their codes, I began to understand that they have no idea about what the program should do so that it would generate the desired output, in other words, they were trying to get the output without trying to understand the statement problem. In programming, one should not rush to the ending, we should first understand the problem statement, then know its inputs, then processes, and last is to find the desired output. I will prove my  example, the problem statement is "The sum of x and y is equal to 5. The value of y is 3.  Find x. If sum of x and y is equal to 5 then print 'Correct' else print 'Incorrect' ". By using this problem statement, we can assume that the inputs are:

x

y=3

sum=5

And the processes:

To find x

x=sum-y

To check if sum of x and y is equal to 5 and then print 'Correct' else print 'Incorrect':

if(x+y==sum)

print "Correct"

else

print "Incorrect"

Now that we have both the inputs and processes we can use it to write a code on any programming language. My personal favorite is PHP so I will use PHP in writing the code. The code should be:

<?php

$y=3;

$sum=5;

$x=$sum-$y;

if($x+$y==$sum)

echo"Correct";

else

echo"Incorrect"; 

?>

By using this code I got:

Easy right? Try it yourself. Experiencing starts with trying. Even talent can be overcome by hard work. Good luck :)
