  2. Create a program to handle file opening and closing exceptions using try-catch block.
    • Expected Output:
      Error: Could not open file.

Templates

  1. Create a template function maximum() to find the maximum of two numbers of any data type (int, float, double).
    • Expected Output:
    Maximum of 5 and 10: 10 Maximum of 3.5 and 2.8: 3.5
  2. Create a template class Stack to implement stack operations (push, pop, display) for any data type.
    • Expected Output:
      Stack: [5, 10, 15]

Standard Template Library (STL)

  1. Create a program to demonstrate the use of vector to store and display a list of integers.
    • Expected Output:
    Elements: 1 2 3 4 5

    • Expected Output:
      Student Marks: John: 85 Alice: 90

String Handling

  1. Create a program to find the length of a string without using the standard library function strlen().
    • Expected Output:
    Length of String: 12
  2. Create a program to reverse a string without using the standard library function strrev().
    • Expected Output:
      Reversed String: olleH

Input and Output Manipulation
