use rs232 ;i need help

[qwertyqqqq]

I want to compare two char array and if they re the pin b0 is high#include

<16f877.h>
#fuses XT,NOWDT,NOPROTECT,NOBROWNOUT,NOLVP,NOPUT,NOWRT,NODEBUG,NOCPD
#use delay(clock=4000000)

#use rs232 (baud=9600, xmit=pin_C6, rcv=pin_C7, parity=N, stop=1)
int d;
int flag=0;
int flag1=0;
int i=0;
char c;
char yan[20];
char ert[7]={'*','c','e','t','i','n','$'};
#int_rda
void serihaberlesme_kesmesi()
{
output_low(pin_b0);
c=getch();
putc(c);
if ((flag==0)&& (c=='*'))
{
flag=1;
}
else
{
if ((c=='$') && (flag==1))
{
flag=0;
for(d=0;i;d--)
{
if(yan[i]!=ert[i])
{
i=0;
flag1=1;
continue;

}
else
{
if ((flag1=1) && (yan[0]='c'))
{output_high(pin_b0);}
}

}
}
}

if(flag=1)
{
yan[i]=c;
i++;
}
}
void main()
{

setup_adc_ports(NO_ANALOGS);
setup_adc(ADC_OFF);
setup_psp(PSP_DISABLED);
setup_spi(SPI_SS_DISABLED);
setup_CCP1(CCP_OFF);
setup_CCP2(CCP_OFF);
setup_timer_1(T1_DISABLED);
setup_timer_2(T2_DISABLED,0,1);
output_low(pin_c5);
enable_interrupts(int_rda);
enable_interrupts(GLOBAL);
while(1)
{

}
}
this is my program can u help me?

1st of all use the code tags. This makes your code more readable.

Secondly, a char array is basically a string but NOT null terminated, you can still use some of the string functions if you know for sure certain things. If your char arrays have fixed sizes :-

strncmp(str1, str2, 10) will compare the first 10 characters of the 2 strings.

look at the CCS help for more info or search google for strncmp.
