+# Reverse a String
+###### C++ 11
+
+### 1. Approch to solving the problem
+
+Iterate through the string to be reveresed starting from the end and add each those letter to another string that is output.
+
+### 2. How to compile and run this
+
+In Windows - I used the Visual Studio C++ compiler, move to the proper directory and run:
+
+```
+cl.exe /EHsc src/ReverseString.cpp
+ReverseString.exe
+```
+
+### 3. How this program works
+
+I take an input string and iterate through it backwards taking each letter and adding it to the back of the output string.
