I have some C code I'm working with, and I'm finding errors when the code is running but have little info about how to do a proper try/catch (as in C# or C++). For instance in C++ I'd just do: try{ //some stuff } catch(...) { //handle error } but in ANSI C I'm a bit lost. I tried some online searches but I don't see enough info about how to make it happen / figured I'd ask here in case anyone can point me in the right direction. Here's the code I'm working with (fairly simple, recursive method) and would like to wrap with try/catch (or equivalent error-handling structure). However my main

Introduction In every textbook on C/C++, you'll find an operator precedence and associativity table such as the following: http://en.cppreference.com/w/cpp/language/operator_precedence One of the questions on StackOverflow asked something like this: What order do the following functions execute: f1() * f2() + f3(); f1() + f2() * f3(); Referring to the previous chart I confidently replied that functions have left-to-right associativity so in the previous statements the are evaluated like this in both cases: f1() -> f2() -> f3() After the functions are evaluated you finish the evaluation like

Possible Duplicate: What does “static” mean in a C program? What does the static keyword mean in C ? I'm using ANSI-C. I've seen in several code examples, they use the static keyword in front of variables and in front of functions. What is the purpose in case of using with a variable? And what is the purpose in case of using with a function? Roux hass Just as a brief answer, there are two usages for the static keyword when defining variables: 1- Variables defined in the file scope with static keyword, i.e. defined outside functions will be visible only within that file. Any attempt to access

When terminating a string, it seems to me that logically char c=0 is equivalent to char c='\0' , since the "null" (ASCII 0) byte is 0 , but usually people tend to do '\0' instead. Is this purely out of preference or should it be a better "practice"? What is the preferred choice? EDIT: K&R says : "The character constant '\0' represents the character with value zero, the null character. '\0' is often written instead of 0 to emphasize the character nature of some expression, but the numeric value is just 0 . http://en.wikipedia.org/wiki/Ascii#ASCII_control_code_chart Binary Oct Dec Hex Abbr

Having namespaces seems like no-brainer for most languages. But as far as I can tell, ANSI C doesn't support it. Why not? Any plans to include it in a future standard? C does have namespaces. One for structure tags, and one for other types. Consider the following definition: struct foo { int a; }; typedef struct bar { int a; } foo; The first one has tag foo, and the later is made into type foo with a typedef. Still no name-clashing happens. This is because structure tags and types (built-in types and typedef'ed types) live in separate namespaces. What C doesn't allow is to create new namespace

This question already has an answer here: Why is the asterisk before the variable name, rather than after the type? 13 answers Just wondering if there's any difference between: char* var; char *var; or is it just a matter of preference (spacing)? There is no difference in this case. However, you should prefer char *var; . This is because the * is associated more closely with the variable name and is not part of the base type . For example, if you do this: char* a, b; What you have is a , a pointer-to- char , and b , a char . This is confusing! Since the * character is closer to the char
