Explanation of Solution

Method of writing a function template:

Before starting to write a function template, first create a regular function with proper parameter list and definition. Then, convert the regular function into a function template.

Steps involved for converting a function into a function template:

• Define a regular function.
• Test the regular function with sample data and debug the function whether it works properly or not.
• Once it is executed correctly, then convert into a template by adding template prefix with type parameter.

Example:

For example, consider the following function “multiply” is used to multiply the given values as follow as:

//Regular function

//definition of the "multiply" function

int multiply(int a,float b)

{
