Merging of Two arrays in C Programming

//-------------------------------------------------------
//  Title : Merging of the Two arrays
//  a  - First Array
//  b  - Second Array
//  c  - Resultant Array after merging
//  i  - Subscript variable for array a
//  j  - Subscript variable for array b
//  k  - Subscript variable for array c
//  n1 - Total number of elements in array1
//  n2 - Total number of elements in array2
//-------------------------------------------------------
