help me with debug errors

[john2020]

I need to know if theres any errors in this code?

#define tPosition struct { int X, int Y } Position *
int myfunc(int x)
{
tPosition a, b;
if (x = 0xF178)
{
unsigned int z = 3;
return a.X * z;
}
return b.X + z;
}

 

[Pretest]

replace the #define with typedef and the * after position by ;

In the function replace tPosition with Position.

Also check for the width of the int type to make sure it bigger than 16 bit.

do you mean this way?did u notice only error with first line? i think structure definition is wrong here and also variables a and b are used without assigning values here...what about the if loop??have modfied the code as shown below, see now if its ok.

typedef  struct          {           int X;            int Y;         }Position;int myfunc(int x) { Position a, b;unsigned int z = 3; if (x = 0xF178) { return a.X * z; } return b.X + z; }

You are right you need to define the z variable outside of the if. If you don't assign value when declaring a variable, you may see unexpected result.
