findtotalcurtain

The function "findtotalcurtain" is written in the C programming language. The purpose of this function is to calculate the total number of curtains in a given room.

Here is the step-by-step explanation of the code:

1. The function "findtotalcurtain" is declared and defined, which means that it will perform a specific task when called.

2. The function takes two parameters: "room_width" and "room_length". These parameters represent the width and length of the room, respectively. These values will be provided by the user when calling the function.

3. Inside the function, a variable "curtain_width" is declared and initialized with a value of 2. This variable represents the width of each curtain.

4. Another variable "curtain_length" is declared and initialized with a value of 4. This variable represents the length of each curtain.

5. A variable "total_width" is declared and initialized with the result of dividing the room width by the curtain width using the division operator "/". This calculation gives the number of curtains that can fit horizontally in the room.

6. Similarly, a variable "total_length" is declared and initialized with the result of dividing the room length by the curtain length. This calculation gives the number of curtains that can fit vertically in the room.

7. To calculate the total number of curtains, a variable "total_curtains" is declared and initialized with the product of "total_width" and "total_length" using the multiplication operator "*". This calculation gives the total number of curtains that can fit in the room.

8. Finally, the value of "total_curtains" is returned as the output of the function.

This function can be used to calculate the total number of curtains required for a room of a given width and length. By providing the dimensions of the room, the function will return the total number of curtains needed to cover the entire area.
