Question

How do I mark the end of a char* vector with ‘\0’ to null-terminate it?
If i have char* vector:

 char* param[5];

I thought of either

 param[4] = '\0';

or

char c = '\0';
param[4] = &c;

but none of them seem to work?

param is a char-pointer vector, supposed to point to 5 strings(char-vectors).

Ok you are trying to end a vector of strings, something similar to what is passed to main as argv. In that case you just need to assign a null pointer:

param[4] = 0;
