Convert 32 bit applications to 64 bit applications
The principal cause of difficulties when converting 32-bit software to 64-bit software is the alteration of size of the particular int type with regards to the long and also pointer kinds. Whenever transforming 32-bit programs to 64-bit programs, just extended sorts as well as tip types alteration of dimensions through 32 parts to sixty four pieces; integers associated with the kind int stop at thirty-two parts in size.
This can cause trouble with info truncation when setting tip or lengthy types in order to do int sorts. Additionally, problems with signal expansion may appear when setting expression utilizing types smaller than the dimensions of an int for an unsigned extended or perhaps a tip.

The basic origin of the problem during the conversion of 32-bit applications to 64-bit is the alteration of the size of the “int” type with regards to the pointer and “long” types. During conversion, the only types that are converted from 32-bit to 64-bit are the “long” types and “pointer” types. “int” types just stay as 32-bits and this can cause problems during data truncation once the “long” or “pointer” types are assigned to “int” types.
The chief dissimilarity among 32-bit and 64-bit compilation environments is the difference in data-type models. For 32-bit application, ILP32 model is the C data-type model. And LP64 model is the data-type model for 64-bit applications.
