    "Invalid conversion from int to *int"

    So I'm trying to learn how to use pointers, but my compiler has decided I'm not allowed to. Every time I try to assign anything to a pointer I get this error:
    Code:
    error: invalid conversion from ‘int’ to ‘int*’ [-fpermissive]
      pNumber = number;
    This is my code.
    Code:
    #include <iostream>
    
    int main()
    {
    	int number = 6;
    	
    	int * pNumber;
    
    	pNumber = number;
    
    	return 0;
    }
    What am I doing wrong here?

    You need to take the address:
    Code:
    pNumber = &number;
    C + C++ Compiler: MinGW port of GCC
    Build + Version Control System: SCons + Bazaar

    A pointer can only store the address of the partilcular variable location.
    It cannot store the content.

    Hope i could help...
