Thread: strings...

I'm working on a small little project to simulate the linux OS for complete newbies and I was wondering, I kept trying to find a way to use ifs and else statements for them to analyze the char variable and do something. But I can never get it to read the char variables in any of the if's statements. I've researched the net a bit, and have not been successfull. A snippet of the code is:

printf("\n > ");
gets(temp);
if (temp=='ls')
{
printf("testing");
}

else { printf("Something went wrong....beta code"); }



btw, yes i declared all vars, and i did everything needed, i'm not THAT stupid ;P. So if someone could please hook me up, i'd be very thankful.


p.s. if your a C string god, is there anyway to add an effect to the printed characters to make then like seem to type by themselves on letter at a time? If not, thanx anway. =)

i think (temp=='ls) should be (temp=="ls")
or try if (strcmp(temp,"ls")) ....

small?

Is usleep ANSI?

I did a quick man and the documentation is written by Redhat people which suggests to me that it may be specific to Linux or even just Redhat.

I guess it wouldn't matter if you were running it on Linux but I would have thought that one wouldn't write a Linux simulator to run on Linux.

Alternately you could write a loop that does nothing but look at the time between key outputs.

eg.

Code:

for(i=0;i<(sizeof(string[])/sizeof(char));i++)
{
  putchar((int)string[i]);
  starttime=time();
  /* loop for some time */
  while(wasted!=WAITTIME)
  {
    wasted=difftime(starttime,time());
  }
}

Code:

char temp[100];
gets(temp); 
if ( strcmp(temp,"ls") == 0 )
{ 
   printf("testing"); 
}

Later on, you will need to use fgets instead of gets - because gets is a big bug trap
