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?
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.
This has happened before, when I try to run a code it will say "blah.exe has stopped working" and I would have to change the code in some way to make it work.
I'm using Code Blocks but for some reason it doesn't process alt symbols. You know... alt symbols are like this: ☺♫↓☻♪♥↕. Code Blocks says that they're "invalid characters". Is there any attatchments or mods so Code Blocks can process them or will changing the settings?
I find myself in a position where I am repeating the same pattern of, write shared lib, compile, link shared lib, write app lib "sandbox" dependent on shared lib, write shared lib, compile, link, write...
At each level of dependency I have to carry over previously shared libs, search directories, etc. How to automate this process, so I spend less time linking after each layer?
how to get opengl working in code blocks? I have tried putting in the libraries and such in the correct folder. But I get an error saying that glut32.dll could not be found. I am running a 10.5 code blocks
In my c project in code blocks , I have added another source file (KillerMoves.c) and a header file under the same name (KillerMoves.h). I added the "include guard" to prevent double inclusion. But from some reason, the program suddenly crashes with no warning or specific error. Without the new files,the program runs without any problems. This is the source .c file:
Code:
#include "KillerMoves.h" void initKillersTable(){ for(int i = 0; i < 15; i++){ killersTable[i] = -1;
I'm using Code:Blocks 12.11 on windows 7, with the built-in MinGW compiler. When I try and compile a program that has an error in it (misnamed variable, missing include, extra semi-colon somewhere, anything) instead of saying something about what went wrong it just has this:
Process terminated with status 1 (0 minutes, 0 seconds) 0 errors, 0 warnings (0 minutes, 0 seconds)
I want to show my output in one line. But my output breaks to next line even before endl is encountered.code blocks horizontal scroll bar in console? is it c++ formatting issue or console issue?
I want to make a basic RPG text based games with multiple classes. but I wan to know how In one class I make a variable and in another and can call the variable.
for exmaple
class2: int hi = 1; class1: class2 a; hi = 2; cout << hi; 2
I'm trying to compile my project, but is not working, the weird thing is if i put all the code in 1 file it compile, but not in a project, source code:
I downloaded glew 1.9.0 files and dragged the lib, include, and bin of the glew into the mingw folder within Code Blocks. I don't know if this is the right thing to do I don't understand how this stuff works. Anyway, I tried to compile my openGL 3.0 program that uses glew and I got this error: The procedure entry point _glewBindArray could not be located in the dynamic link library glew32.dll, How do I install glew properly?
I have created a game.It is working fine in codeblocks, but when I am trying to run it outside codeblocks, it opens and closes immediately. I have pasted all the necessary files and dlls in root folder and debug folder. Here is the code:-
I will keep this simple as I have the code written for my testing software program, I just want to add a feature of randomly generating the answer choice output order, I do not want to randomly output the full questions, but instead the choices (answers to the question), for example =
As you can see I would like to output the answers, choices randomly as in answer choice 3 will appear at the top instead of 1. and so on, it doesn't matter if the numbers move with the txt as the numbers beside the questions are txt.
I am writing for loop with a switch so that scores can be inputted in by a judge. The issue that I am running into is that I will put out an the text then the test happens and the code puts out the switch statement 5 times with random number. Here is what I have written.
Code: int main() { int diver; int option; int Judge; cout << "Enter Divers Name:";
this is my code i want to put the part where i have it do multiplication and addition into functions. and then call them so that it can run the addition and multiplication. Heres my code
# include <iostream> using namespace std; int main(){
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; } }
I am trying to generate 3 random numbers between 1 and 6 using a function called generate_rand. but everytime im having an error : no oprators "<<" matches these operands and the last error was :end of file found before the left brace
my program is the following :
# include<iostream> #include<cstdlib> using namespace std;
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++.
I have a function which sometime takes more than 24 hours to run. So I want a code which will check the time and exit the function if the function executin is not successful and return to main function.
1: Sort Alphabetically 2: Sort Grades Increasing Order (Student) 3: Sort Grades Increasing Order (Project) 4: End Program Enter choice:
Why my sort is not working. Also, I want to keep the same random numbers for the continuation of the program, I don't want new randomized values when I display the table.
