C :: Function Return Code / Value?

Sep 27, 2014

I have a function that needs to return a "uint8_t" value. However before doing the processing I need to perform a test on the argument to check if it's between expected boundaries. Although this function works it gives (a logical) warning that not always a value is returned although expected. What is the normal way for functions like these where I normally should return e.g. -1 in case the test doesn't succeed and otherwise the uint8_t (t) value?

Code:
uint8_t myFunc(int a) {
if (a >= 0 && a <= 100) {
// Perform actions
uint8_t = ...
return t;
}
}

C :: Clrscr Function In Code Block

May 1, 2014

I start working on CodeBlocks and stuck in a situation. The situation is that I want to clear my output screen every time the main function calls some other functions. To do that I use clrscr() function but its not working. After spending some times on web, I found that its a non-standard function so this extension is not used by the new compiler's. Another thing I find to use < cstdlib > library. But unfortunately it do works only for C. It works for C++.

C++ :: Random Function - Cannot Use In Code Blocks

Jan 30, 2014

I'm unable to use the function random(num); in Code::Blocks. It shows the error : error: 'random' was not declared in this scope while the same code works fine in Borland's Turbo C++. How do I rectify this?

C++ :: Identify End Of Function Code At Running Time

Apr 16, 2013

I want to implement some "debugger like" tool (very limited one, just identify at running time the current stack trace, and print messages from the user) on some code that the user wrote. what I get from the user is a function name (in the beginning of it's declaration), and when the user want to print some message he uses some print macro I should implement.

My target is printing the stack call, and all the messages that the user wrote, in the right place on the running place.

By what c++ feature can know on running time that a specific function code has ended??

Its easy to push a function to some vector when it called (since I get its name from the user), but when it ends and return to the function called it...

C++ :: Code Stops Executing After GetScores Function

Nov 11, 2014

I am currently working on a c++ project that will input students and process their grades. I encountered a problem and my code stops executing after the getScores function. Im not sure what the problem is, but im guessing its something within the function and the loops.

//Name: getScores
//Description: Will get scores for student
//Parameters: None
//Return: testScore
double getScores()

C++ :: Compiler Not Always Be Able To Insert Code For A Function Inline

Apr 14, 2013

This: "The compiler may not always be able to insert the code for a function inline (such as with recursive functions or functions for which you have obtained an address), but generally, it will work."

For a function inline why wont it work for a recursive function or a function for which you have obtained an address?

Why cant the compiler still insert the inline?

I wrote a program with a recursive() called finder. But it dose not work properly,at run time it becomes to a infinite status. How to detect the error at runtime. Here is the code.

#include<stdio.h>
void finder(int x,int y);
int tot;

[Code] ....

I think the error is the changing value of x after a round of for loop.

C++ :: How To Add A Loop / User-defined Function And Array / Structure To Code

Apr 24, 2012

We had to write a "selling program for computers, laptops and tablets", which I did but for the extra credit, we have to have those three points in the application and I have tried but how to do the "extra credit" part, which I really need.

1.) A loop to prompt the user if they would like to place another order

2.) At least one user-defined function

3.) An enumerated data type, array or struct (structure)

I did one of these three, it's a "DO WHILE" loop asking users if they want to make another order, it's right at the beginning of the code.

Code:

#include <iostream>
#include <string>
#include <iomanip>
#include <fstream>
using namespace std;
double desktop();//function prototype
double laptop();
double tablet();

C++ :: Function In One Src File Called From Code In Different Src File - Linker Error

Mar 27, 2015

I have a function in one src file called from code in a different src file.

In ig_cfunc.cpp

Code:
#include "ig_tools.h"
int x2_count = 0.0;
float rel_branch_degree_tmp = 0.0;
string type;
vector<int> is_disp_type;

[Code] ....

I am getting a linker error,

Code:
ig_cfunc.cpp:1609: error: `calc_rel_branch_degree' undeclared (first use this function)

I have deleted all of the objects and recompiled to make sure that everything is in sync. I can't see what the issue is here and I'm not sure what to do next. This code actually worked until I changed the name of the function, so the types are all correct and such. This is the format I use for all external functions ....

C++ :: Reducing Code Duplication From Common Code Calling Common Class

Apr 13, 2014

I have a class 'A' which is almost perfect for my needs. Class 'B' uses class 'A' I've now designed Class 'C' and Class 'D' and noticed that there is a good chunk of code in class 'B', 'C' and 'D' for using Class 'A' is duplicated. I've separated out this code in specific, standalone functions in each of the classes. Now I'm wondering where this code should go. At the moment, the functions are duplicated in the three calling classes (B, C and D). Placing the functions into class 'A' would break the single responsibility principle. Inheritance to add functionality would likely break both SRP and LSP. The one that seems that it may work is composition.

However, Is designing a complete class just for a few functions over kill?

Would it be valid for classes 'B', 'C' and 'D' to access both the new class 'E' (which would depend on A) and the old class 'A' (which would have to be the same instance as the instance in the new class 'E'), or should the new class 'E' provide sufficient functionality so that Classes B, C and D don't need to access Class A directly? It would seem that its then an incomplete interface of the original object with additional functionality (ie, incompatible) Or should I do it a completely different way?

C++ :: DLL Project On Code Blocks

Feb 24, 2015

I'm pretty new to C++ and I'm on Binary Trees in "Jumping into C++"! I've just created a DLL project on Code::Blocks, and I cannot get it to build and run: "You must select a host application to "run" a library..." is the message that I'm getting when I run the main code file. It's had no changes to it (except for a few extra, unnecessary line feeds), and it's the file which Code::Blocks generates on a DLL project.

C++ :: Why Does This Code Crash Half Way Through

Jan 16, 2014

whats wrong with this code, I'm trying to parse a .js file and replace all the ";" with "; " i.e add a new line after each ";". So I load the file into a char[] buffer then assign a string to this contents of this buffer. Then loop char by char through using an iterator and check for a ";", if found use replace. So int i gets to about 85898 then crashes with unknown error, 'i' should reach about 175653. It does work up till it crashes. And, is this not a simpler way to load a file into a buffer, there is in C.

Code:
#include <iostream>
#include <fstream>
#include <algorithm>
#include <vector>
#include <stdlib.h>
int main()

C :: Using PlPlot Library In Code

Mar 8, 2013

I am in try to use PlPlot library (for plotting) in C with code::blocks IDE (ver 10.05) on windows-7 plateform. I downloaded "plplot-5.9.9.tar" and unzipped it. In documentation it is not very clear to me (I am not expert in using third party lib.), how this library can be used with code::blocks i.e. where I have to save the lib, what should be added in compiler and debugger settings etc. It also seems from document that "makefile" (linux type!!) is necessary for Windows also? I am also unaware of MSYS makefile generator (given on Wiki page) on windows?
