Modern  Periodic Table project in c:

Scope of the project  : It is developed using the C programming language for the purpose of storing name, symbol, atomic number, atomic weight.

Description of the project  :

This project is to explore or to display the stored information. You can search an element by using any of the following method:

1.    By name of element

2.    By symbol of element

Program will tell the user about element atomic mass,atomic weight,formulaes,electron configration,meliting point and all which is famously relatives.

C functions uses:

Filing,if else condion,arrays,functions,2d array ,strings,pointers.

CODE:

#include<stdio.h>

#include<string.h>

void input(char arr[],int count1); //function prtotype

main()

{

//intailization

int i=0,temp=0,t=0,count1=0;

char arr[100];

char exit;

do{

printf("Enter element name or symbol:");

scanf(" %[^\n]s",&arr);

 for(i=0;arr[i];i++)  //this loop will convert uppercase alphabets to lowercase

    {

    if(arr[i]>=65 && arr[i]<=96)

    {

    temp=arr[i];

    temp=temp+32;

    arr[i]=temp;

    }

    }

    count1++;  //this count1 for print searching history once time on the top of file

    input(arr,count1); //function calling

    printf("Do you want to search another element?\nif yes press y if want to exit press n\n");

    scanf(" %c",&exit);

    i=0;

    temp=0;

}while(exit!='n');

return 0;
