Sample C Program To Implement Minimum Spanning Tree Using Functions, Pointers & Structures.



ALGORITHM:

STEP 1: Start the program.
STEP 2: Assign MAX a constant value of 20.
STEP 3: Declare a structure edge with structure variable *front.
STEP 4: Define the functions and variables required in the program globally.
STEP 5: Call the function create_graph() inside the main function.

STEP 6: Call the function make_tree().
STEP 7: Set a for loop using i.
for(i = 1; i <= count; i++)
STEP 8: Print the values of tree[i].u and tree[i].v
STEP 9: Stop the program.


FUNCTION OF CREATE_GRAPH ( )

STEP 1: Declare the local variables.
STEP 2: Read the number of nodes n.
STEP 3: Calculate the value of max_edge as
max_edge = n * (n - 1) / 2.
STEP 4: Set a for loop using i.
for(i = 0; i <= max_edge; i++)
STEP 5: Read the values of origin and destiny.

STEP 6: Check whether origin and destiny are equal to 0.
STEP 7: If so exit the loop using break statement
STEP 8: Read the weight of the current edge wt.
STEP 9: Check the following condition.
if(origin > n || destin > n || origin <= 0 || destin <= 0)
STEP 10: If any of the condition is true, print “invalid edge!” and decrement the value of i by 1.

STEP 11: Else call the function insert_pque(origin, destin, wt).
STEP 12: Check whether i is less than n - 1, if so then exit with an error message.


FUNCTION OF MAKE_TREE ( )

STEP 1: Declare the local variables.
STEP 2: Initialize the variable tmp, node1, node2.
STEP 3: Assign the values for node1, node2.
STEP 4: Calculate and print the values of root_n1 and root_n2.
STEP 5: If the two roots are not equal, call the function insert_tree.

STEP 6: Assign the value of root_n1 to father [root_n2].


FUNCTION OF INSERT_TREE (int i, int j, int wt )

STEP 1: Declare the local variables.
STEP 2: Increment the value of count.
STEP 3: Assign values to tree[count].u, tree[count].v, tree[count].weight.


FUNCTION OF INSERT_PQUE (int i, int j, int wt )

STEP 1: Declare the local variables
STEP 2: Allocate the memory space of size, struct edge for tmp.
STEP 3: Assign values to tmp -> u, tmp -> v, tmp -> weight.
STEP 4: Check for the following condition.
if(front == NULL || tmp -> weight < front -> weight)
STEP 5: If any of the conditions are true assign the value of front to tmp -> link and assign tmp to
Front.

STEP 6: Else set a while loop and declare following.
q = q -> link;
tmp -> link = q -> link;
q -> link = tmp;
if(q ->> link == NULL)
tmp -> link = NULL;

FUNCTION OF STRUCT EDGE *DEL_PQUE( )

STEP 1: Declare the local variable.
STEP 2: Assign the value of front to temp.
STEP 3: Print the values of processed edge and return the value of tmp.
