C,CPP Programming & Variable Naming Rules

File Ambiguity #

file: can be only filename, or full/relative path + filename.
location: full/relative path + filename.
filename: only name part, no path in string.
path: full/relative path w/o filename.

Common & Suggested Usages #

//Common   → Suggested
chars      → charSize
bytes      → byteSize
int  * buf → int  *p_intListing
char * buf → char *p_inputFile
ifstream in→ ifstream inputStream

IF Statement Evaluation #

if (c) is: if(c != 0)
if (!c) is : if (c == 0)
similar for boolean vars:
false === 0 and true === !0 === !false
However, all true evaluates to int 1:

cout << false  // 0
cout << true   // 1

Cuda #

var pre-fix #

ph_ pointer of a variable in host RAM.
pd_ pointer of a variable in device mem.
pb_ pointer of a variable in block shared mem.

allocate & free mem #

Everytime, when doing: cudaMalloc()
The following 2 actions are also required: cudaMemcpy() and cudaFree().
