declare in .h file
(1)void Fu::Init(int b,int h);
imp in cpp file
(2)void Fu::Init(int B,int h)
{
m_1=B; //implicit replace B with b,but missing change B
m_H=h;
}
[changeSignature] on Init(Imp line)
To change second parameter h to int H.
After that,the imp line and declare both become:
void Fu::Init(int b,int H);
But the m_1=B; B is invalid symbol.
it should be automatic change :like m_1=b;
