Regarding C pointers

Hi buddies,

char *cTest = new char[10];
printf(" \nThe strlen(cTest) is : %d\n",strlen(cTest));

The output of this printf statement should be 10 but itz giving 14.

help please, why it so..

regards,
ashok

You arent initialising that data to anything before testing the length


All strlen does is travel up the string until it finds a zero byte......

When you allocate that memory, it could hold anything........only use strlen when you know there's a string in that area of data

It works if you use the sizeof operator and a "static" array:

Code:

char cTest[10];
printf("sizeof(cTest) = %d\n", sizeof(cTest));
