I’m having some problems with my C code and get the error in the title. First off, Uint16 is defined as: I use two variables in the function where I get the error, they are defined as: I call the function like this: and the function definition is like this: and lastly, the declaration in … Read more
You have the following line of code: Inside the main function. There are 2 major problems with this. Function declarations cannot appear inside of another function. The line I quoted needs to appear outside of your main function as follows:int lookup(…..) //code here int main(…) { //more code here } Even though you declare the … Read more
You need to compare, not assign: Because you want to check if the result of strcmp(“hello”, “hello”) equals to 0. About the error: lvalue required as left operand of assignment lvalue means an assignable value (variable), and in assignment the left value to the = has to be lvalue (pretty clear). Both function results and constants are not assignable (rvalues), so they are rvalues. … Read more
\n is the newline character, while \r is the carriage return. They differ in what uses them. Windows uses \r\n to signify the enter key was pressed, while Linux and Unix use \n to signify that the enter key was pressed. Thus, I’d always use \n because it’s used by all; and if (x == ‘\n’) is the proper way to test character equality.
unsigned really is a shorthand for unsigned int, and so defined in standard C.
I try to do this operation so see if this operation will take only the complete part (20%4) or all (20.4%4.4) And got this compiler error: expression must have integral type
The rules of C says that you can’t initialize an array using a pointer. Instead define the array then copy to it: Then you can not define empty arrays. An array must have a size. And using the array newArr in the main function is wrong anyway since the function you call returns a pointer. So newArr must be a pointer as … Read more
Currently you’re generating code for x86-64 – you need to select a MIPS compiler from the popup menu above the assembly pane: After you’ve done that you’ll probably see generated code like this: Note that the compiler has optimised away some of the redundant operations in the original C code. If you want to see an … Read more
There’s hardly any “immediately” regarding networking, stuff can be lost on the way, and an operation that should be performed immediately in theory might not do so in practice, and in any case there’s the end to end transmission time. However connect() on a TCP socket is a blocking operation unless the socket descriptor is … Read more
Copy-pasted from here: (just add void to the main() arguments list in order for this to work in C)
