CS304 Question No: 1

CS304 Question No: 2
Each try block can have ______ no. of catch blocks.
► 1
► 2
► 3
► As many as necessary.
CS304 Question No: 3
Function templates should be used where code and behavior must be identical.
► True
► False
Rational This will help us to standardized the codes.They are meant for the situations where same functionality can be adapted to more than one type or class. It will reduce the need of repeating the entire code for each type.
