m is normal variable while *m is pointer variable. Pointer variable is a variable that can address of another variable.. Ex: int a=10,*p; p=&a; Then p contains a address, *p return a value 10. Read about pointers in C. https://www.sololearn.com/learn/C/2933/

first you need to understand pointers. lets say you declare a variable a: int a=1 then 1 is the actual value. &a lets you access its adress if you declare a variable like this int *b; it is a pointer. you can store the adress of a in b like this: b=&a; to acess the value that is stored in memory on which b points you can use *b roughly. Understanding pointers is essential. I suggest to look it up in detail.
