Function template: In C++, a function template is referred as a “generic” function, which can work with different data types. While writing a function template, a programmer should use a “type parameter” to denote a “generic” data type instead of using the actual parameter. The compiler generates the code, when it encounters a function call to a function template. This code will handle the particular data type which is used in the function call. The compiler identifies the argument type and generates the code to work with those types. The generated code is referred as “template function”. Example: For example consider the following function template for finding a cube of value: template <class T> T cube(T x) { return x * x * x ; } A function template must begin with the keyword “template” and it is followed by a pair of angle brackets, which contains one or more “generic” data types. A “generic” type must start with the keyword “class”, followed by an argument name which stands for the data type. The statement “T cube(T x)” is referred as function header, where “T” is a “type parameter”, “cube” is the function name and the variable “x” is declared for the type “T”.

Function template:

In C++, a function template is referred as a “generic” function, which can work with different data types.

While writing a function template, a programmer should use a “type parameter” to denote a “generic” data type instead of using the actual parameter.

The compiler generates the code, when it encounters a function call to a function template. This code will handle the particular data type which is used in the function call.

The compiler identifies the argument type and generates the code to work with those types.

The generated code is referred as “template function”.

Example:

For example consider the following function template for finding a cube of value:

  template <class T>

  T cube(T x)

  {

  return x * x * x ;

  }

A function template must begin with the keyword “template” and it is followed by a pair of angle brackets, which contains one or more “generic” data types.

A “generic” type must start with the keyword “class”, followed by an argument name which stands for the data type.

The statement “T cube(T x)” is referred as function header, where “T” is a “type parameter”, “cube” is the function name and the variable “x” is declared for the type “T”.

A cylinder of diameter 10 cm rotates concentrically inside another hollow cylinder of inner diameter 10.1 cm. Both cylinders are 20 cm long and stand with their axis vertical. The annular space is filled with oil. If a torque of 100 kg cm is required to rotate the inner cylinder at 100 rpm, determine the viscosity of oil. Ans. μ= 29.82poise

Make the following game user friendly with GUI, with some simple graphics The following code works as this: The objective of the player is to escape from this labyrinth. The player starts at the bottom left corner of the labyrinth. He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. The player can move only in four directions: left, right, up or down. There are several escape paths in all labyrinths. The player’s character should be able to moved with the well known WASD keyboard buttons. If the dragon gets to a neighboring field of the player, then the player dies. Because it is dark in the labyrinth, the player can see only the neighboring fields at a distance of 3 units.
