removing last 5 or 6 chars

[nabeels786]

ive got a ip like: <ip>:<port>

i wanna strip teh :<port>

there what i came up with

	bool passed=false;
	for(int i=0;i<=strlen(server_name);i++){
		if(passed){
			*server_name=' ';
		} else{
			if(*server_name==':'){
				*server_name=' ';
				passed=true;
			}
		}
		*server_name++;
	}

it returns the lst 8 with the port, and i cant figure out why
