Simple question is: why do you write
char *foo;
and not
char* foo;
Let me explain: for me (coming from Java) a declaration is something like
<variable-type> <variable-name>;
In the above case I declare a variable named foo of type char* (as it is a pointer pointing to char). But wherever I read c/c++/c#-Code it looks like a variable named *foo of type char. The compiler does not care about whitespaces but I as a developer do.
tl;dr What I ask for is a good explanation for writing char *foo instead of char* foo (what, as explained, seems more convenient for me).

What is the difference between char and char*? char[] is a character array whereas char* is a pointer reference. char[] is a specific section of memory in which we can do things like indexing, whereas char* is the pointer that points to the memory location.
char* is how you declare a pointer to a char variable. It's useful when you want a string with unknown length. 1st example: char name[10];
The fundamental difference is that in one char* you are assigning it to a pointer, which is a variable. In char[] you are assigning it to an array which is not a variable.
char *A[] is an array, and char **A is a pointer. In C, array and pointer are often interchangeable, but there are some differences: 1. with "char *A[]", you can't assign any value to A, but A[x] only; with "char **A", you can assign value to A, and A[x] as well.
Think of the following declaration:
char *p, c;
This declares a pointer to char called p and a character variable called c. This shows that it isn't exactly correct to think of variable declaration as having the simple and clear format you described.
