Data flow testing techniques use to identify the anomalies in data variable definition and use in white box testing techniques. For following two programs do Def-Use Associations for all variables in program respectively and identify where data anomalies exist

void pow (int x, y) { float z; int p; read (2) x = 0 y = 0 if (z 20) { x = sqrt (z) if (O's x &&xs 5) y = f (x) else y = h (3) } y = g(x,y) print (y) if(y=0) p=0-y; else p= y; z=1.0; while (p !=0) { z=z* x; p=p-1; } if (y
