Corruption of Head

Rahal1813 (6)
I am writing a code which includes a dynamic variable. I am getting an error about a corruption of head.

I knew that somehow I misused the dynamic variable but I can not see how.

Please find my code below and thank you for assistance.

new int(nblock);

This creates allocates a single int with the value of nblock.

 
 
new int[nblock];

This would allocate an array of nblock integers.

Line #29 should declare a array of it's with square brackets:

 
 
blck_str = new int[nblock];


You might as well combine lines#28 and #29:

 
 
int* blck_str = new int[nblock];
