Best can give some comments in the code thank you!

Fyi:

 # include & lt; stdio.h> 
#include  

Int my_cmp (const void * a, const void * b) 
{
Int * p=* (int * *) a; 
Int * q=* (int) * * b; 
Return * * p - q; 
} 

Int main (void) 
{
Int * pa [10], I; 

//array initialization 
for(i=0; i<10; I++) 
{
Pa [I]=(int *) malloc (sizeof (int)); 
The scanf (" % d ", pa [I]); 
} 

//quick sort 
Tree (pa, 10, sizeof (int *), my_cmp); 

//output sort the results 
for(i=0; i<10; I++) 
{
Printf (" % d % c, "* pa [I], I!=9? '\ t' : '\ n'); 
} 

//handling, destruction of 
for(i=0; i<10; I++) 
{
[I] free (pa); 
} 

return 0; 
}

Reference:

 # include & lt; stdio.h> 
Int main (int arg c, char * argv []) 
{
* pa int a [10], [10]. 
Int * temp; 
Printf (" Input tan number: "); 
for(int i=0; i<10; I++) {
The scanf (" % d ", & amp; A [I]); 
Pa [I]=& amp; A, [I]. 
} 

for(int i=0; i<10; I++) {
for(int j=0; j<10-1; J++) {
If (* pa [j] & gt; * pa [m + 1]) {
Temp=pa [j]; 
[j]=pa pa [j + 1); 
Pa [j + 1)=temp; 
} 
} 
} 


for(int i=0; i<10; I++) {
Printf (" % 4 d, "* pa [I]); 
} 
printf("\n"); 
for(int i=0; i<10; I++) {
Printf (" % 4 d, "pa [I] - a); 
} 
printf("\n"); 

system("pause"); 
return 0; 
}
