hi, i am trying to write a method that checks if the terminator of an email is valid.
its takes two parameters char * addrress which contains the email
and char * terminator which ontains the terminator
my problem is it seems that i am not copying the termitor in the string address to my buffer correctly or my terminator arrray is empty/
here is an e.g A terminator is a final string such as "com" or "net" that ends an
email address. The set of all valid terminators is stored in the
parameter array "terminators"


int isTerminator(char * address,char *terminator){
int index=0;
char buffer[55];
int length=strlen(address);
//getting the length of my first index
while(address[length]!='.'){
length--;
}
length++; // incrementing by one due to o indexing so my first character starts at index 23

//copying frm string to my array buffer
while(address[length]!='\0'){
buffer[index++]= address[length++];
}

int i=0;

for(i;i<5;i++){
if(0==strcmp(buffer,terminator))
return 1;
}

return 0;

}

int main(int argc, char** argv) {

const int length = 5;
char *terminators[length];
char * address1, address2;

terminators[0] = "com";
terminators[1] = "net";
terminators[2] = "edu";
terminators[3] = "ie";
terminators[4] = "tv";

address1 = "fana.bosss@north.south.com";
address2 = "I.am@flh";







// int x=containsvalidIdentifiers(mm);
int y= isTerminator(address1,terminators);

printf("%d",y);

return 0;
}
