It depends on the implementation, which is free to assume your parameters are valid (i.e. not null in this case). The behaviour may or may not be reproducible from execution to execution, or from one implementation/platform to another.
You can specify a width on string fields, e.g. And then whatever’s printed with that field will be blank-padded to the width you indicate. The – left-justifies your text in that field.
You can install gcc by running setup-x86.exe or setup-x86_64.exe again. The gcc package is in the Devel category:
The typedef would be However, this is probably a very bad idea, because the resulting type is an array type, but users of it won’t see that it’s an array type. If used as a function argument, it will be passed by reference, not by value, and the sizeof for it will then be wrong. A better … Read more
FFCALL lets you build closures in C — callback = alloc_callback(&function, data) returns a function pointer such that callback(arg1, …) is equivalent to calling function(data, arg1, …). You will have to handle garbage collection manually, though. Relatedly, blocks have been added to Apple’s fork of GCC; they’re not function pointers, but they let you pass around lambdas while avoiding the need to build … Read more
you said ‘I copy the pointer to this array into another variable’. The problem is as soon as you do a realloc, the original pointer is no longer valid. I dont see the reason to copy the pointer to a variable?
Use the %lf format specifier to read a double: Wikipedia has a decent reference for available format specifiers. You’ll need to use the %lf format specifier to print out the results as well:
As I can understand from your assignment statement in while loop I think you need array of strings instead: Note: By doing = in while loop as below: you are just assigning address of string (its not deep copy), but because you are also writing “only address of strings” so I think this is what you wants. … Read more
Do it like this: Note: strtok modifies the string its tokenising, so it cannot be a const char*.
In Lua 5.2 or earlier, both tostring(10) and tostring(10.0) result as the string “10”. In Lua 5.3, this has changed: That’s because Lua 5.3 introduced the integer subtype. From Changes in the Language: The conversion of a float to a string now adds a .0 suffix to the result if it looks like an integer. (For instance, the float 2.0 will be printed as 2.0, not … Read more
