What are the characteristics of a good program in C++

The program should be written in a good style so that it is understandable to a reader. A good program is efficient in solving the given program. 

Here are some of the characteristics of a good program :

Effective and Efficient 

User Friendly 

Self-Documenting Code 

Reliable 

Portable 

I. Effective and Efficient

The program produces correct results and works faster, taking into account of the memory constraints. 

II. User Friendly

The user should not be concerned about inside the program, a program should work with the user by understandable messages and user work should be very low. The user should only be responsible to provide input the rest of the program should do. 

III. Self-Documenting Code

A good program must be self-documented. The source code uses meaningful names for variables, subprograms and other constants. 

IV. Reliable

The program must be able to handle unexpected situations like wrong data or no data, it should display a proper message or error message when dealing with no data or wrong data input. 

V. Portable

A good program should be able to run on all platforms without any errors or difficulties.

Putimage function in c

putimage function outputs a bit image onto the screen. Declaration:- void putimage(int left, int top, void *ptr, int op); putimage puts the bit image previously saved with getimage back onto the screen, with the upper left corner of the image placed at (left, top). ptr points to the area in memory where the source image is stored. The op argument specifies a operator that controls how the color for each destination pixel on screen is computed, based on pixel already on screen and the corresponding source pixel in memory. c smiling face animation This animation using c draws a smiling face which appears at random position on screen. See output below the code, it will help you in understanding the code easily. C programming code #include<graphics.h> #include<conio.h> #include<stdlib.h>   main() { int gd = DETECT, gm, area, temp1, temp2, left = 25, top = 75; void *p;   initgraph(&gd,&gm,"C:\\TC\\BGI");   setcolor(YELLOW);
