+## Template
+
+Templates are a way to dynamically "generate" functions from a template that accept user-defined arguments. They can be used instead of overloading a function. Example:
+
+```cpp
+#include <iostream>
+using namespace std;
+
+// One function works for all data types. This would work
+// even for user defined types if operator '>' is overloaded
+//        Type (i/d)    Func  Arg  Arg
+template <typename T> T myMax(T x, T y)
+{
+    return (x > y) ? x : y;
+}
+
+int main()
+{
+    // Call myMax for int
+    cout << myMax<int>(3, 7) << endl;
+    // call myMax for double
+    cout << myMax<double>(3.0, 7.0) << endl;
+    // call myMax for char
+    cout << myMax<char>('g', 'e') << endl;
+
+    return 0;
+}
+```

+
+## Overloading functions
+
+Overloading a function is a way to make a function execute different instructions when different types of arguments are passed using the same function name.
+
+```cpp
+#include <iostream>
+using namespace std;
+
+
+void add(int a, int b)
+{
+  cout << "sum = " << (a + b);
+}
+
+void add(double a, double b)
+{
+    cout << endl << "sum = " << (a + b);
+}
+
+// Driver code
+int main()
+{
+    add(10, 2);
+    add(5.3, 6.2);
+
+    return 0;
+}
+```
