how to create an adjacency matrix?

i want to input values as

a[0][0]=1 a[0][1]=3
a[1][0]=2 a[1][1]=3

1 3
2 3

i want an adjacency matrix from this as:
m[0][0]=0, m[0][1]=0, m[0][2]=1
m[1][0]=0, m[1][1]=0, m[1][2]=1
m[2][0]=1, m[2][1]=1, m[2][2]=0

0 0 1
0 0 1
1 1 0

How can i do?
please help me with codes....

How do you want the program to run?

I'd imagine that you prompt the user to enter connections and save a 1 in the corresponding place for the adj matrix

i.e.
_______________________

Enter Connection:
add 1-3
OK

add 2-3
OK

add 3-3
OK

del 3-3
OK

print
OK

0 0 1
0 0 1
1 1 0
________________________________

Is this what you want?

yes right!

OK - Let's start with the first command

Prompt for input and read the response.

You will need to start this on your own - printf and scanf are probably a good starting point :)
