Using C programming

Define a structure type element_t to represent one element from the periodic table of elements. Components should include the atomic number (an integer); chemical symbol, the name, and class (strings). Write separate subroutines (functions) using C program to (1) Read the periodic table from file and store them in structure array (2) find out the elements in each class (3) print out the name of the distinct classes and the elements in each them in another file.

Uses the following as the input text file:
