gets problem in c

I've installed NetBeans 7.0.1 today When I try to execute C program with "scanf" in it it's giving strange errors

This is what I wrote:

It keeps on running until I enter something in the output console.

After entering its shows the printf statement and shows "RUN FAILED"

Can anybody tell me what should I do to make this right?


Your printf is not getting flushed so it is not showing until the program ends.

You are not returning a value from main() explicitly, so the result of scanf() is being returned, which is 1 which is interpreted as program failure.

SOLVED!!! - "PROBLEM with Scanf()" when reading c, char input reading problem in Scanf() method in "C - Programming". specifier in Duration: 5:21 Posted: Feb 1, 2017 This video DEMONSTRATES , how to !!RESOLVE!! the char input reading problem in Scanf() method in "C - Programming".


You need to return 0 at the end of main if not it assumes there was an error.

printf before scanf doesn't show printf string before input · Issue #218 , What steps will reproduce the problem? #include int main(int argc, char* argv[]){ int n; printf("Please input a number\n"); scanf("%d", &n); printf("The number is %d\​n", n); Programs built with the Cygwin or MSYS compilers are not affected by this. Successfully merging a pull request may close this issue. When reading input using scanf, the input is read after the return key is pressed but the newline generated by the return key is not consumed by scanf, which means the next time you read a char from standard input there will be a newline ready to be read. One way to avoid is to use fgets to read the input as a string


You are not returning 0, which indicates successful termination to the OS and you are not putting a trailing \n on your printf, causing the line to not print (stdin is buffered):

#include <stdio.h>

int main()
{
    int n;
    printf("Enter the number:\n");
    scanf("%d", &n);
    return 0;
}

We invoke the function printf() to print the string "Hello, world! After the loop is completed, Line 22 prints the result with a proper description. Your printf is not getting flushed so it is not showing until the program ends. You are not returning a value from main() explicitly, so the result of scanf() is being returned, which is 1 which is interpreted as program failure.


A C program without a return value will result in undefined behaviour (which is unanimously considered a Bad Thing©). The compiler is allowed free rein in what it returns here, it appears to be returning the result of scanf() but it could be returning some atmospheric entropy for all the C Standard cares.

As for the line not printing, that's because you're using printf() on a buffered terminal, you'll want to add \n at the end. The reason for this harks back to ancient Unix ways that have long since been forgotten by all but the very sagest of Unix gurus.

As for nothing happening until you input something, that's because scanf() blocks until input is received, in case you weren't already aware of that. It is possible to use non-blocking IO calls, but I'm not sure if that's in the scope of your question. (please define "make this right").

scanf format string, A tutorial for using unit testing in C/++ projects in NetBeans IDE and Oracle Solaris int arg; fflush(stdout); scanf("%d", &arg); printf("factorial(%d) = %ld\n", arg, You can right-click the project node, or the Test Files folder, or a test subfolder, and If you look at the function you can see that it does not actually test anything,  x = 10, str =. The problem with above code is scanf() reads an integer and leaves a newline character in buffer. So fgets() only reads newline and the string “test” is ignored by the program. The similar problem occurs when scanf() is used in a loop.


Netbeans 7.0.1 internal terminal doesn't work when program uses , scanf format string refers to a control parameter used by a class of functions in the Otherwise, the function will not perform correctly because it will be attempting to As scanf is designated to read only from standard input, many programming Eclipse · Geany · GNOME Builder · Microsoft Visual Studio · NetBeans. printf () and scanf () functions are inbuilt library functions in C programming language which are available in C library by default. These functions are declared and related macros are defined in “stdio.h” which is a header file in C language. We have to include “stdio.h” file as shown in below C program to make use of these printf
