delete[] problem

[XSquared]

Whenever i try to execute my code, I get the following error:

Debug Error!

Program: <Program Path>

DAMAGE: after Normal block (#44) at 0x002F2AC8.

Here's my code (only relevant code posted):

for(int i = 1; i < 4; i++)
{
	char * tempStr = new char[strlen(argv[i])];
	strcpy(tempStr, argv[i]);
	
	for(int j = 0; j < strlen(argv[i]); j++)
	{						
		if(argv[i][j] == 'A') tempStr[j] = '0' + a;
		if(argv[i][j] == 'B') tempStr[j] = '0' + b;
		if(argv[i][j] == 'C') tempStr[j] = '0' + c;
	}

	Numbers[i - 1] = atol(tempStr);

	delete[] tempStr; //Error on this line.

	tempStr = NULL;
}

I'm using MSVC++ 6 Ent, btw.

Silent but deadly

char * tempStr = new char[strlen(argv[i])];
strcpy(tempStr, argv[i]);

So say argv[1] is 10 chars plus NULL....you make room for 10 chars (strlen())...and the NULL goes into the 11th char - no-man's land

This is then picked up in delete []....and the debug build will issue an error

Thanks a lot. It works now.
