Question

What is the runtime of the following code segments?  Prove that your answer is correct.

1. 

void foo(int* array, int size)

{

  int sum = 0;

  int product = 1; 

  for (int i=0; i < size; i++)

  {

    sum += arrray[i];

   }

 for (int i =0; i < size; i++)

 {

    product *= array[i]; 

  }

 cout << sum << " ," << product; 

}

 

 

2.

void printPairs ( int * array, int size) {

   for (int i=0; i<size; i++)

   for (int j=0; j < size; j++)

     cout << array[i] << " + " << array[j];

}

 

3. 

void reverse(int * array, int size) {

for (int i=0; i<size/2; i++)

 {

   int other = size - i-1;

   int temp = array[i];

   array[i] = array [other];

  array[other] = temp;

}

}
