Question

Write a complete C program.

Define a structure type element_t to represent one element from the periodictable of elements. Components should include the atomic number (aninteger); the name, chemical symbol, and class (strings); a numeric field forthe atomic weight; and a seven-element array of integers for the number ofelectrons in each shell. The following are the components of an element_t

structure for sodium.11 Sodium Na alkali_metal 22.9898 2 8 1 0 0 0 0

Have the user enter the data for one element and then display that data on the screen.

Here is the C program for the above task:

#include <stdio.h>

#include <string.h>

//declaring element_t struct

struct element_t {

   int atomicNum;

   char name[20];

   char symbol[5];

   char class[20];

   float atomicWt;

   int electronConfg[7];

};

int main() {

   struct element_t element; //element variable of type element_t

   /* take input for user */

   printf("Enter atomic number: ");

   scanf("%d", &element.atomicNum);

   printf("Enter element's name: ");

   scanf("%s", element.name);

   printf("Enter element's symbol: ");

   scanf("%s", element.symbol);

   printf("Enter element's class: ");

   scanf("%s", element.class);

   printf("Enter atomic weight: ");

   scanf("%f", &element.atomicWt);

   printf("Enter element's electronic confg: ");

   int i;

   for (i = 0; i < 7; ++i) {

       scanf("%d", &element.electronConfg[i]);

   }

   printf("\n");

   /* print data to screen */

   printf("atomic number: %d\n", element.atomicNum);

   printf("element's name: %s\n", element.name);

   printf("element's symbol: %s\n", element.symbol);

   printf("element's class: %s\n", element.class);

   printf("atomic weight: %f\n", element.atomicWt);

   printf("element's electronic confg: ");

   for (i = 0; i < 7; ++i) {

       printf("%d ", element.electronConfg[i]);

   }

   printf("\n\n");

}
