help getting a grib on argc and argv

hello people i m srry i kinda dont understand the need of argc and argv like i dunno what they do like for example this code here it doesnt even run or anything

Code:

---

#include < stdio.h>
int main(int argc, char** argv)
{
    int i;
    printf("argc = %d\n", argc);
    for (i = 0; i < argc; i++)
            printf("argv[%d] = \"%s\"\n", i, argv[i]);
        return 0;
}

---

it would be be cool if someone like give me the idea on how they work

To get a grip on command line arguments read the tutorial.

oh i understand it now but will it only work in cmd ? like can i also use command line arguments to like produce a programmer that opens a txt ? without cmd like in a window ? or argc and argv used only with cmd ?

Please post clear questions? From your last post it is impossible to figure out what you're tryin' to say.

like i got a txt file on the same folder i m in is it possible to make a program that opens it without needing to add do it from cmd like from the program itself?

like when you like have a text file like in the same like folder u like just add its path to like the cmd line of the program in like cmd like so you like can get like the filename from like argv and u like not have to like hardcode it like in the source code itself like that

There's no need to butcher simple works like "sorry."

And your language is so idiosyncratic I have a hard time believing you're not a native English speaker, but like, whatever and stuff.

(Idiosyncratic doesn't mean "idiotic")

To answer a question that the OP may have been asking: it is possible to associate your program with .txt files (either by clicking on it normally or having a separate item in the right-click menu) so that when you choose to open a file with your program, the full path to the file you opened is passed as a command-line parameter to your program. I'm not going to say more than that in case I'm on the wrong track here . . . .

here is a sample assigment i did from the k&r book which uses the commandline arguments . i think some gui libraries uses commandline parameters internally to keep track of some things but i am not that far into my studies of c that i can say if that is true or not.

Code:

---

#include <stdio.h>
#define IN 1
#define OUT 0

int main(int argc,char *argv[]){
       
        int c;
        int nl,nw,nc,state;
            nl=nw=nc=state=0;
        FILE *fp;
       
        if(argc != 2)
          {
                  fprintf(stderr," %s: too few arguments for format\n",argv[0]);
                  return 1;
          }
         
          if((fp=fopen(argv[1],"r")) != NULL)
          {
                /* we opened a file to read it and count it*/
        while((c=getc(fp))!= EOF)
        {
                        nc++;
                    if(c=='\n')
                      nl++;
                if(c==' '||c=='\n'||c=='\t')
                  state=OUT;
                  else if(state == OUT)
                  {
                          state = IN;
                          ++nw;
                  }
        }
                fprintf(stdout,"%d %d %d\n",nl,nw,nc);
        }
        else
        {
                fprintf(stderr,"error in opening file %s\n",argv[1]);
                return 1;
        }
                return 0;
}
