Question

I am trying to make a program which needs scans in more than one word, and I do not know how to do this with an unspecified length.
My first port of call was scanf, however this only scans in one word (I know you can do scanf(“%d %s”,temp,temporary);, but I do not know how many words it needs), so I looked around and found fgets. One issue with this is I cannot find how to make it move to the next code, eg

scanf("%99s",temp);
printf("\n%s",temp);
if (strcmp(temp,"edit") == 0) {
  editloader();
}

would run editloader(), while:

fgets(temp,99,stdin);
while(fgets(temporary,sizeof(temporary),stdin))
    {
        sprintf(temp,"%s\n%s",temp,temporary);
    }   
if (strcmp(temp,"Hi There")==0) {
  editloader();
}

will not move onto the strcmp() code, and will stick on the original loop. What should I do instead?

Answer 1

I would scan in each loop a word with scanf() and then copy it with strcpy() in the “main” string.
