I've started to learn a C language and i am using netbeans IDE.
I tried the most simple classic = printing "Hello World".
code
int main(int argc, char** argv) {
printf('Hello World!');
return (EXIT_SUCCESS);
}
When i run projects, netbeans writes BUILD SUCCESSFUL (total time: ...)
but then it writes
read from master failed
: Input/output error
RUN FAILED (exit value 1, total time: 414ms)
How to make it work?
This is the Hello World program. It includes the relevant library header file. I added the newline with \n to ensure the output buffer is flushed.
#include<stdio.h>
int main(void) {
printf("Hello World!\n");
return 0;
}
Program output:
Hello World!
Your problem is coming from Netbeans IDE. Right click your project and go to properties. In the properties, click run and change the console type to standard output.

I typed this program on code blocks but it is showing error on int main line
Here's the program
#include <stdio.h>
int main()
{
printf("Hello");
return 0;
}
The message return is " multiple definition of main"
The sample code is correct. It might be an IDE configuration error. Use gcc to compile your code on Linux and on Windows you can install MinGW and execute from a command window.
I ran a 4 line code and it compiled and linked without a hitch, but it refuses to print anything
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(){
char* a = "book";
printf("%s\n", a);
return 0;
}
After compiling it and running the executable, nothing happens.
No error in the code.
Just write getch(); or getchar() before return 0;
to holding the output screen.
getch() or getchar() will hold the ouput screen for getting the user's input.
Works fine for me.
You've tagged this with terminal; if you are running it from the terminal, you should see some output, in my experience.
If you are running from an IDE,
keep the window open using Kapil K.'s answer;
keep the window open using an IDE setting, if there is one; or
find out where your IDE is putting the executable file, and run that from a terminal.
I have installed MinGW on netbeans for C and C++ programming.
Here is a simple code that I am trying to run on netbeans :
#include <stdio.h>
int main(int argc, char** argv) {
printf("Inside Main...\n");
int n;
printf("Enter : ");
scanf("%d", &n); // When I remove this line, it is working.
printf("You have entered %d.", n);
return (1);
}
Whenever I try to access any value from netbeans console, I don't see anything.
Output with scanf(...)
Output without scanf(...)
And if I try to run these code from cmd, all are working
for scanf() you must use Netbeans External Terminal !
Normal Run
You can also use Netbeans Standard Output !
But this is more misleading.
While you see an empty Terminal do input 123
after hit enter , you get the output all at once .
I had the same issue while running a CPP program.External output didn't helped me. I set the console type to Standard output and it solved the issue.
Right Click cpp Application-->properties-->run--->Consoletype to standard output
After downloading and installing Code::Blocks with MinGW, I just started a new console project on it and it created a main.c file with this content:
#include <stdio.h>
#include <stdlib.h>
int main()
{
printf("Hello world!\n");
return 0;
}
And it does compile. However, when I run it, no "Hello world!" is shown in the console and there is a message like
Process terminated with status 1993077897 (0 minutes, 3 seconds)
or
Process terminated with status -1073741510 (0 minutes, 7 seconds)
in the build log.
I can truly say that I just don't know what went wrong.
Problem solved: Kapersky was doing its job too well and blocked the process before it could even display a simple "Hello world". It warned me a long time after that, asking me repeatedly to delete the executable.
try:
int main(void)
{
printf("Hello World");
return 0;
}
I may be wrong, but i think the problem is in the main() i think you need to change that to main(void)
Just try this
Go to Settings->Compiler->Reset Defaults Hope it works!
I am trying to learn C and I have just installed Xcode on my Mac. I wanted to run the first program that was already written
#include <stdio.h>
int main(int argc, const char * argv[])
{
// insert code here...
printf("Hello, World!\n");
return 0;
}
and got build failed.
I created a program in C. The libraries have been downloaded.
Thanks
Are you trying to learn C or Objective-C? As far as I know, XCode is only appropriate for Objective C.
Also, can you post your compiler error, that will help alot.
