string comparison
PostPosted: Sun Apr 26, 2009 12:32 pm     Reply with quote
I am not that versed in c programming.

I am trying to take input from an rs232 connection and compare it to a string constant (a word).

This example does not compile....it is my understanding the I compare the string from the 'gets' and compare it to the constant. I have even tried strcmp ("word","word")...I am clearly not understanding something.

Someone please set me on the right course.

Thanks a million.

Code:

#include <16F690.h>
#fuses INTRC_IO, NOWDT, NOBROWNOUT, PUT, NOMCLR
#use delay(clock=8000000)
#use rs232(baud=4800, xmit=PIN_B7, rcv=PIN_B5)


#include <string.h>
//=============================
void main()
{
char input[6];
int x;
printf("Password: ");
while(1)

  { gets(input);

    puts(input);
 x = strcmp(input, "word");
if (x == 0)
    printf ("strings are the same \n\r");

   printf ("password typed is %s. \n\r",input);



  }

}
