+// Implemenmtation of  stack data structure
+/*
+    This implementation uses a generic type T to allow the stack to store elements of any type. 
+    The stack is implemented using an array and has methods for pushing, popping, peeking, checking 
+    if the stack is empty, and getting the size of the stack. The comments explain each step of the 
+    implementation.
