Compare chatacter to another?

[MOHH]

i feel like such an amature again... what i'm trying to accomplish is to find the preriods in an ip address.

#include<string.h>
#include<iostream.h>
#include<conio.h>

void main()
{
	void return_class(char ip[]);
	char ip[] = {"155.25.54.1"};
	return_class(ip);


}
void return_class(char ip[])
{
	int sLength;
	char firstoctet[4];

	// get string length
	sLength = strlen(ip);
	
	// loop character array retrieving all characters the 
	// preceed the first period character

	for(int x = 0; x < sLength; x++)
		if(ip[x] == ".")
			cout<<"period"<<endl;
	getch();
}

i've also try tried the strcmp() functioins but all i get is cannot covert from char to char*

if(strcmp(ip[x], ".") == 0)

no go there! how can i loop through a character array and compare that character with another?

Thank, (so frustrating, when its so simple in vb)

char *s = ip;
for(int x = 0; x < sLength; x++)
		if( *s== '.') cout<<"period"<<endl;

The loop isn't endless merely 'pointer-less'

alright, but you test the same character all the time...
