+=====if=====
+The 'if' statement is one of many methods to control the flow of a program.  It tests whether or not a certain condition is true, and then executes code based on the test.
+<code cpp>
+#include <iostream>
+using namespace std;
+int main(){
+if (TRUE){
+   cout << "This statement will be executed";
+}
+if (FALSE){
+   cout << "This one will not";
+}
+return 0;
+}</code>
+The output of this simple program is as follows:
+<file>
+This statement will be executed
+</file>
+The 'if' statement is commonly used with the 'else' statement.  Else gives a program direction in case a condition of an if statement evaluates to false.
+It can be used to clean up the above code a bit:
+<code cpp>
+#include <iostream>
+using namespace std;
+int main(){
+if (TRUE){
+   cout << "This statement will be executed";
+}else{
+   cout << "This one will not";
+}
+return 0;
+}
+</code>
+These two programs produce the exact same output.
