Modified as follows, for your reference:

 # include 

Int pos_InArr (int arr [], int n, int nKey); 

Int main () 
{
Int nKey, m;//n. 
,13,14,15,16,17,18,19,11,20 int arr [10]={12}; 
Printf (" please input you want to query nKey: \ n "); 
The scanf (" % d ", & amp; NKey); 
M=pos_InArr (arr, 10, nKey); 
If (m!=1) 
The location of the printf (" % d to % d \ n ", nKey, m); 
The else 
Printf (" the value is not found! \n"); 

return 0; 
} 

Int pos_InArr (int arr [], int n, int nKey) 
{
int i; 
for(i=0; iIf (arr [I]==nKey) 
return i; 
//return - 1; 
} 
return -1;//return 0; 
}
