I want to store the value of every variable ikj in

where read[i] is " i=20" ,"j=30" , "k=i*j"

and then display the value of k . And I am even successful though, but if there's

" i=20" ,"j=30" , "k=i*j", "m=30", "n=20", "p=m*n"

then only result of p gets displayed when I want value of even k to be displayed, I dropped the idea of dynamically creating variables as it would be hectic for very long codes. Thank you
