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.
