The

refer to the original poster Zhi nine lyp reply:

#include
Void separate (float x, int * y, float * z);
Void main ()
{
Float data, * z;
Int * y;
Printf (" input from the keyboard a real data: ");
The scanf (" % f ", & amp; The data);
To separate (data, y, z);
Printf (" % d, % f ", * y * z);
}
Void separate (float x, int * y, float * z)
{

X * y=(int);
* z=x * y;

}
Why do I always run out

}

CodePudding user response:

Z and y is pointer is no point to data space

CodePudding user response:

 
Float data, * z=(float *) malloc (1); 
Int * y=(int *) malloc (1);

For your reference ~

Two Pointers are wild pointer, you need to allocate space, or directly with normal variables

CodePudding user response:

 
Void separate (float x, int * y, float * z) 
{
X * y=(int); 
* z=x * y; 
}

 
Float data, * z=(float *) malloc (1); 
Int * y=(int *) malloc (1); 
Printf (" input from the keyboard a real data: "); 
Scanf_s (" % f ", & amp; The data); 
To separate (data, y, z); 
Printf (" % d, % f ", * y * z);

reference 4 floor wise men know already should good karma response:

 
Float data, * z=(float *) malloc (1); 
Int * y=(int *) malloc (1);

wrong new friends don't learn

refer to 6th floor wise men know already should good karma response:

 
Void separate (float x, int * y, float * z)

perpetuated this misunderstanding first
You can't have a good look at the parameters of the malloc what meaning be?
All pass 1 oh
