{ 
   int x; 
   int iNumbers[3] = {2, 4, 6}; 
  
   printf("\nThe current array values are: "); 
  
   for ( x = 0; x < 3; x++ ) 
      printf("%d ", iNumbers[x]); //print contents of array 
  
   printf("\n");  
  
   squareNumbers(iNumbers); 
  
   printf("\nThe modified array values are: "); 
  
   for ( x = 0; x < 3; x++ ) 
      printf("%d ", iNumbers[x]); //print modified array contents

void squareNumbers(int num[]){     
   for (int x = 0; x < 3; x++ ) 
      num[x] = num[x] * num[x]; //modify the array contents
