Question

I have two pointers,

char *str1;
int *str2;

If I look at the size of both the pointers let’s assume

str1=4 bytes
str2=4 bytes

str1++ will increment by 1 byte, but if str2++ it will increment 4 bytes.

What is the concept behind this?

Answer 1

In the provided scenario:

• char is 1 byte long
• int (in your platform) is 4 bytes long

The ++ operator increments the pointer by the size of the pointed type.
