For help,,,, just had a afternoon have a clue, and read online again disorderly into a piece of information,,
Is like that, I want to join in the program a dynamic structure array, but there are old tip pointer errors, monitoring the variable indicates the q - & gt; A [I] CXX0030: error: unable to calculate the value of the expression
Pray god give directions
