C program to hide the mouse pointers.

Posted on by Sandeepa Nadahalli
C program to hide the mouse pointers.
In this program, we hide the mouse pointers using graphics.h and dos.h library functions.
To use graphics.h, we have to install the drivers in to the the system by using the initgraph() function.
In this program,we also check the condition that mouse pointer is available or not. Read more about C Programming Language . and read the C Programming Language (2nd Edition). by K and R.

C Program to generate Graph using grphics.h

Posted on by Sandeepa Nadahalli
C Program to Generate the graph sheet using the grphics.h library. To use graphics.h, we have to install the drivers in to the the system by using the initgraph() function. Here  we derive the graph of input sizes verses time taken for input sizes. x axis represents inputs(0,10000,20000,—-), y axis rep time(0,0.05,0.1,0.15—). Read more about C Programming Language.
