Create a file in C programming and write "Hello world!" in the file

I have tried this code on my device, and it creates a file named "hello.usr" and prints the text "Hello world!" successfully.

#include<stdio.h>    
int main()
{    
    FILE *opening;
    opening = fopen("hello.usr","w");
    fprintf(opening,"Hello world!");     
    fclose(opening);
    printf("Writing to the file was successful.\n");
    printf("Closing the program");
    return 0;
}

But the online judge where I'm submitting this program gives me an error. Your program's output is shorter than expected

How can I overcome this?

A comment says:

Write a program that prints the text "Hello world!" into the file "hello.usr". The file does not exist, so it must be created. Finally, the program must print a message on the screen indicating that writing to the file was successful. The text printed to the file must exactly match the assignment. Example output: Writing to the file was successful. Closing the program. The output of the program must be exactly the same as the example output (the most strict comparison level).

I'm not sure what you mean by online judge, but it's a good thing to use "\n" at the end of your writes. "\n" is the special character that jumps a line.

#include<stdio.h>    
int main()
{    
    FILE *opening;
    opening = fopen("hello.usr","w");
    fprintf(opening,"Hello world!\n"); // Here    
    fclose(opening);
    printf("Writing to the file was successful. Closing the program");
    return 0;
}

Reading your comment now, I don't think the solution is related to "\n"'s.

Some other good things you should consider are:

  • Adding blank spaces after your ","
  • Maybe add some blank lines for your own comprehension

If I was going to write the same things, I'd do like this:

#include<stdio.h>    

int main() {    
    FILE* file = fopen("hello.usr", "w");
    fprintf(file, "Hello world!");

    fclose(file);
    printf("Writing to the file was successful. Closing the program.");

    return 0;
}
