+1) Work flow : 
+
+Step 1 : 
+First output, *For CSC * CSR , press 1 otherwise 0..*
+For matrix multiplication, enter 1
+For rest of operations press 0
+
+Step 2 :
+On pressing 1
+For matrix multiplication, am generating two random matrices and multiplying them.
+First matrix dimensions, non zero density and -ve numbers density needs to be entered.
+Similarly, for 2nd matrix.
+
+After input details for matrices, am outputting the matrices using ; for row breaker, So that the same matrix can be copied and pasted into matlab/octave , for verification purpose.
+
+After multiplication am outputting the result into COO Row sorted format, and providing additional option if you want to print matrix as m x n structure. Press 1, to print in m x n	format.
+
+Step 3 : 
+On pressing 0
+To genrate COO, CSR, CSC and CSC trnsform
+Matrix dimensions, non zero density and -ve numbers density needs to be entered.
+
+Again am outputting the matrix using ; for row breaker.
+After this, am directly converting the input matrix into CSR and CSC format, and outputting the CSR format and CSC format only.
+
+Step 4 :
+In this step, am giving options to print the input matrix in form of CSR, CSC or COO as matrix structure of m x n.
+Also, am givng option to perform Row operations. 
+*Print options <20x20 COO-1, CSR-2, CSC-3 
+CSC transform-4*
+Using options 1,2 and 3 matrix can be printed into structure of m x n by sendind respective CSR or Format's data to printmatrix().
+
+Step 5 :
+For Performing row transfomations on CSC format :
+*Enter r1, k1, r2, k2*
+A[r2] = k1*A[r1] + k2*A[r2]
+Input r1,k1,r2,k2 for performing row operation on CSC format.
+
+After input, am outputting the transformed row, and later printing the matrix in COO Column CSC sorted format, and also outputting the CSC Format.
+
+
+
+2) Function description :
+
+*	Range of values : -10 to 10
+
+*	main()
+main() is taking input that whether you want to multiply matrices or perform rest of operations.
+
+*	struct node{..}
+Defining the structure for linked list storing position and position data, with next pointer.
+
+*	void push(..)
+push() function is taking input as start pointer address, position, position data, and adding it to linked list.
+
+*	coogenerate()
+for generating random matrix in COO Format, and also converting into CSR and CSC, with the option to print matrix.
+
+*	input()
+generates COO matrix.
+
+*	cootocsr()
+generates CSR and prints it.
+
+*	cootocsc()
+generates CSC and prints it.
+
+*	sort()
+Using selection sort for sorting on the basis of first array input.
+
+*	generate2()
+generating 2 matrices for multiplication.
+
+*	multiply()
+Multiplies 2 matrices.
+
+*	csctrans()
+For performing row operations on CSC matrix.
+
+*	printmatrix()
+Prints matrix in m X n structure, having inputs as any one of CSR, CSC, COO.
