Debugging results of 2 1 3; The value of the pointer variable in the main function change?? A little confused

According to the size of the output sequence

According to the size of the output sequence to know which to wrong sorry didn't describe complete

CodePudding user response:

P1=& amp; a;
The p2=& amp; b;
P3=& amp; b;
And p3 didn't you pick up c address!

CodePudding user response:

P3 to take c address, I here in the building code to run result is 3 2 1

exchage function to write the wrong
Void exchage (int * c1, c2) int *
{
Int * t=NULL;
T=c1;
C1=c2.
C2=t;
}

No give p3 c address assignment of the building Lord,
If according to your modifications, the output is the result of the 1, 2, 3 order did not change, suggest that test

CodePudding user response:

P1=& amp; a;
The p2=& amp; b;
p3=& amp; b;

Is the place not to c above, how to test just now is right, the output of 3 2 1
