- 2. CONTENTS HEADER FILES AND FUNCTIONS WORKING DESCRIPTION SOURCE CODE OUTPUT
- 3. WORKING DESCRIPTION This program is based on the Modern Periodic Table of Elements. It showcases all the elements and their basic properties including name, symbol, atomic number, atomic mass, group and period. This program contains 5 options: 1) Search element by name or symbol 2) Search element by atomic number 3) Display Modern Periodic Table 4) Sort elements alphabetically (Using Bubble Sort Technique) 5) Exit
- 4. HEADER FILES AND FUNCTIONS HEADER FILES: 1) iostream.h – For cin, cout 2) conio.h – For console input output functions 3) stdio.h – For standard input output functions 4) stdlib.h – For exit function 5) graphics.h – For graphic related functions 6) string.h – For string manipulation function INBUILT FUNCTIONS: 1) gotoxy() 2) strcmpi() 3) strcpy() 4) clrscr() 5) getch() 6) gets() 7) exit() 8) initgraph() 9) line() 10) outtextxy() 11) rectangle() 12) setcolor() 13) getmaxx() 14) getmaxy() 15) closegraph()
