Why don't I get a warning when I declare a variable with same name in a macro that already exists in a function?
Given your code and the macro above, the C preprocessor generates the following: int main() { int temp = 999; printf("\ntemp: %d", temp); { int temp = 10; } printf("\ntemp: %d", temp); } This is the code that the C compiler receives. The inner { .. } is called a...
Delete weird ANSI character and convert accented ones using Python
You are mixing apples and oranges. b'reuni\xc3\xb3n' is the UTF-8 encoding of u'reuni\u00f3n' which of course is reunión in human-readable format. >>> print b'reuni\xc3\xb3n'.decode('utf-8') reunión >>> repr(b'reuni\xc3\xb3n'.decode('utf-8')) "u'reuni\\xf3n'" There is no "ANSI" here (it's a misnomer anyway; commonly it is used to refer to Windows character encodings, but not necessarily...
Dynamic allocation failing to scan number
This is wrong scanf("%d",&ptr+(i*c+j)); it should be scanf("%d", &(*(ptr + i*c + j))); or since, the ptr points to the addres, you should not dereference the pointer and then pass the address, just scanf("%d", ptr + i*c + j); in your code you are passing the address of the pointer...
Can't reproduce ANSI Encoding to Windows-1256 by C#
The problem is you're converting between encodings. This isn't actually what you're trying to achieve, you just want to re-interpret the encoded text. To do this, you need to get the bytes for your ANSI string and then decode it using the correct encoding. So, leaving out the conversion: var...

Validate scanf parameters
scanf will stop scanning as soon as the first encountered symbol that does not match a format specifier. So if your scanf returns 1 then only the first format parameter was interpreted. switch (scanf("%c,%f,%f", &ch, &p1, &p2)) { case 0: // no parameters were parsed successfully case 1: // only...
How to know in which file it is a referenced fp is currently writing in?
This is OS specific and there is no standard way. If you want to do it consistently you can define some data structure that will hold pathname along FILE handle and pass that around instead of plain FILE: struct file_handle { FILE *fs; char *path; }; Usually, there is no...
Fault in decimal to binary in c
When you get to the last (most significant) bit of 1024, the value of a is 10000000000 (10^10). Except it isn't. Because int is a 32-bit integer, the value of a overflows (twice) and ends up being 1410065408.
Initializing bit-fields
c,struct,initialization,ansi,bit-fields
WRT "speaks about computation, not about initialization", the C89 standard explicitly applies the rules of assignment and conversion to initialization. It also says: A bit-field is interpreted as an integral type consisting of the specified number of bits. Given those, while a compiler warning would clearly be in order, it...

Strange behaviour with DrawTextA, Courier New and Japanese locale
delphi,winapi,unicode,ansi,drawtext
DrawTextA does not convert the text to Unicode. Instead the selected font's charset is used to interpret the supplied text. This is indeed somewhat more complex than the typical A and W suffixed API functions. The use of the font charset allowed non-Unicode programs to display text in multiple character...

Delphi DLL (in XE) must handle TStringList (D2007, Ansi)

David and Jerry already told you what you should do - re-write the DLL to do the right thing when it comes to passing interop-safe data across module boundaries. However, to answer your actual question: the actual string pointers themselves should be correct (??) and thus is there a way...
How do I display ANSI color codes in emacs for any mode?
You could use code below (require 'ansi-color) (defun display-ansi-colors () (interactive) (ansi-color-apply-on-region (point-min) (point-max))) Then you can execute display-ansi-colors via M-x, via a key-binding of your choosing, or via some programmatic condition (maybe your log files have a extension or name that matches some regexp) If you want to do...

Storing integers of a char pointer in c?
Use sscanf, int sscanf(const char *str, const char *format, ...); In this , sscanf(input,"%c%d-%c%d",&ch1,&int1,&ch2,&int2); After getting the input in separate variables, for the alphabets use like this. int3=ch1-'A' + 1; int4=ch2-'A' + 1; Ascii value of 'A' is 65. You need that as 1. So subtract by 'A' and add...
Enumerating executable files in C
