Runtime Memory Error

[itxharsh]

The error during run time is:"Your code has stopped its execution with a non-zero (failure) exit value.This is generally due to run time Exceptions like Memory Access Violation and Floating Point Exception. Please check your code for run time Exceptions and try again.". What could be the error? Please help.

You have a limit to your malloc memory of 15 but you never ensure that k does not exceed this limit.

Amic is not initialized in the function and points nowhere, but then you write to its members.
