I have been asked to make a program named easter.c Now this program involves file handling. Now whenever I try to run the redirection, the terminals shows a message
zsh: command not found: easter
Following is the screenshot. Kindly view the screenshot and help.
./easter
or
export PATH=.:$PATH
Ideally, we should add the complete path of the current directory instead of .

Feedback after running code in vscode;
gcc : The term 'gcc' is not recognized as the name
of a cmdlet, function, script file, or operable
program. Check the spelling of the name, or if a
path was included, verify that the path is correct
and try again.
At line:1 char:40
The code I input;
#include<stdio.h>
int main() {
printf("Hello World")
}
you need to install the gcc compiler on your system and it add to path. here u can take help.

I have a set of C code files named as: hmc.c hopping.c phi4.c and I have an 'infile' which contains value of parameters and a 'Makefile'. How do I run these set of files in Ubuntu?
Previously in Windows I used gcc compiler with command 'gcc hmc.c hopping.c phi4.c' and then press Enter and then 'a infile' and that did the expected job but on Ubunut it isn't working..
Running the makefile should compile and give you an executable. You can do so by entering make in the command line. Make sure you have it installed first.

I'm creating a project and I need to call my executable file name "cluster".
I created a makefile and as long as I call my executable file name by any name other then "cluster" and runs it, it works fine.
However, when I'm calling the file name "cluster" -> make all -> executing (with the name "cluster") I receive the following error:
The error message
What could be the cause of this error? I must be able to call the executable file name that specific name.
If you are on linux, type
which cluster
You will probably find a program called cluster on your path. To execute the one you have made, either change the name to something like Cluster or
./cluster testGraph8 outputfile
The ./ uses the one in the current directory.

I have tried to reading a text file but the array stores only the last line of the text file.
char cleanedText[10000]={'\0'};
while(!feof(fileptr))
{
fgets(cleanedText, 10000 , fileptr);
}
But,the cleanedText stores only the last sentence which is written in the text line.
For example these two is written in the text,
asdasdasd
thisisus
When i print the cleanedText.
The screen just shows thisisus.
What is the problem?
Each call to fgets writes into the same place, overwriting what was there previously.

Cheers, I've isolated the error but I'm not sure how to fix it. Apparently, this line of code,(C language):
parse(getenv("QUERY_STRING"));
It does successfully compile, however when I run the executable the following pops up: puu.sh/nQi41/40e81c4494.png
When I simply comment out that specific line, the code compiles and runes perfectly.
Any possible solutions to this? Thanks in advance
Replace:
parse(getenv("QUERY_STRING"));
by:
char *querystring = getenv("QUERY_STRING");
if (querystring == NULL)
{
printf("Could not get querystring");
exit(1);
}
parse(querystring);
... and read the documentation of getenv.
