The char type can only represent a single character. When you have a sequence of characters, they are piled next to each other in memory, and the location of the first character in that.

287 char* and char[] are different types, but it's not immediately apparent in all cases. This is because arrays decay into pointers, meaning that if an expression of type char[] is provided.
char *str = "Test"; is a pointer to the literal (const) string "Test". The main difference between them is that the first is an array and the other one is a pointer. The array owns its contents,.
Understanding the Context
char *str; // allocate a space for char pointer on the stack str = "1234556"; // assign the address of the string literal "1234556" to str As @Oli Charlesworth commented, if you use a pointer to a constant.
Technically, the char* is not an array, but a pointer to a char. Similarly, char** is a pointer to a char*. Making it a pointer to a pointer to a char. C and C++ both define arrays behind-the-scenes.
What's the difference between char* name which points to a constant string literal, and const char* name
4 OK, I'll take a stab at this. The difference between char and char* is where the compiler puts the variable in memory that your using. char c is a stack declaration. The container holds the.

12 const char* x Here X is basically a character pointer which is pointing to a constant value char* const x is refer to character pointer which is constant, but the location it is pointing can.
char *s = "hello"; So what is the difference? I want to know what actually happens in terms of storage duration, both at compile and run time.
I would like to understand how pointers work, so i created this small program. first of all i create a p pointer, which points to a char. The first question is at this point. If i create a pointe...
