 In C, you might write some code like this:
-<pre>
+<syntaxhighlight lang='c'>
 void myfunction()
+{
      char* mystring = (char*)malloc(n);
      /*some code, which manipulates mystring*/
-     ...
+     //...
      free(mystring);
+}
-</pre>
+</syntaxhighlight>
 This code works, but is error prone. What if the code in the middle exited using a return statement, or a longjmp statement, or in C++, threw an exception? The memory allocated would never be cleaned up, and we would have a memory leak.

 Now if we had this C++ version instead,
-<pre>
+<syntaxhighlight lang='c++'>
 void myfunction()
+{
@@ Line 76: / Line 76: @@
      /*some code, which manipulates mystring*/
 } //mystring is destroyed and memory automatically released
-</pre>
+</syntaxhighlight>
 None of these problems can possibly happen. mystring will ''always'' be released at the end of the function.

 So, this just re-iterates how important C++ containers are, right? Well, yes, but it also shows us that we should always avoid code written like this:
-<pre>
+<syntaxhighlight lang='c++'>
 void myfunction()
+{
-     ...allocate resources...
+     //...allocate resources...
-     ...use resources
+     //...use resources
-     ...release resources...
+     //...release resources...
+}
-</pre>
+</syntaxhighlight>
 If you have code like this, you should put the resources in a class that will manage them and release them at the end of the function. If there is no class like that, then you should write one. This goes for all resources: memory, files, threads, and so forth.

It can be a good idea if either you will have a high down payment or solicit a co-borrower who do not have a bad credit. This will help keep your interest rate lower for the term of the loan.
