Software testing question which requires to draw a data flow os this code.

Using the source code below:

public int Fun1(int x, int y){

k = 0;

while (x <= 10 && k < 10){

if (x%2 != 0){

k = k + y;

k = k 2;

}

x = x + 1;

k = x + k;

}

if (x < 0){

x = y;

k = k + x;

}

return k;

}

1. Draw a data flow graph for the code.

2. Identify all def use clear paths in your graph.

3. Identify all simple paths in your graph.

5. Identify at least one loop free path in your graph.

6. Identify all p-uses/Some c-uses in your graph.
