Value of Char[]

[stefkeh]

Hi Everyone,

i am currently using this code to loop through the possible HWID's:

void checkHWID(char buf[])
{
	int result;
	char HWID00[33] = "3030FBC17070D6DA250C0B28880FF1BE"; 
	char HWID01[33] = "5C030FBC1740D6DA250C0B42880FF1BE";  
	char HWID02[33] = "BAA982909C868C657003547527338892"; 
	char curHWID[7];

	for(int i = 0; i < 3; i++)
	{
		sprintf(curHWID,"HWID%02d",i);
		result = strcmp(buf,curHWID);

	}
}

this correctly loops from HWID00 till HWID02.
but the problem is , it compares buf with "HWID02" but i want it to compare
buf and the value of HWID02.

can anyone help me on this ?

thanks in advance.

Let me guess... ex script language programmer? This doesn't work in C++ (or any other compiled language for that matter). You'd have to put the strings into an array and iterate over the array.

There isn't a way to do it like that. You can't build variable names out of strings like that. But you can do:

void checkHWID(char buf[])
{
	int result;
        char hwids[][33] = { 
            "3030FBC17070D6DA250C0B28880FF1BE",
    	    "5C030FBC1740D6DA250C0B42880FF1BE",  
	    "BAA982909C868C657003547527338892"
        };

	for(int i = 0; i < 3; i++)
		result = strcmp(buf,hwids[i]);
}
