Arrange the following in ‘C’ in the order they can appear logically in a graphics related program : (a) restorecrtmode( ) (b) initgraph( ) (c) DETECT (d) closegraph( ) The correct order of sequence is : Codes :
(c) (b) (d) (a)
To solve this question, we need to understand the context of a graphics-related program in the C programming language. The steps to create and manage graphics in C using the graphics.h library follow a specific order:
DETECT: This is a macro used to automatically detect the graphics driver, typically assigned before initializing the graphics mode withinitgraph(). \(\text{Example: } int \ driver = DETECT;\)initgraph(): This function initializes the graphics system by loading a graphics driver and setting up the monitor into a graphics mode. The setup relies on the driver detected byDETECT.closegraph(): After executing graphics-based operations, this function is used to close the graphics mode and deallocate all the memory allocated by the graphics system.restorecrtmode(): This function restores the screen mode to text mode if it has been altered, completing any graphics program to ensure the system returns to a recognizable state. Although not standard in all environments, it is often implemented in some compilers to switch back to text mode.
Given these steps, the logical order in which these components should appear in a typical C program related to graphics is:
(c) (b) (d) (a)
Thus, the correct answer is option (c) (b) (d) (a), which corresponds to the order: DETECT, initgraph(), closegraph(), restorecrtmode().
