Assignments help

Hey guys, I am suppose to do this but I am stuck, any help would be appreciated.

1 - Sum of Squares
Write a function called sumSquares that returns the sum of the squares of its float array parameter. The function should have a second parameter for the size of the array.

Example

Code:

---

const int MAX_WORD = 10;
const int ROW = 3;
const int COLUMN = 4;
const int SS1 = 4;
const int SS2 = 1;
const int SORTED1 = 8;
const int SORTED2 = 1;
const int SORTED3 = 5;
 
int main()
{
  // Sum of Squares Tests----------------------------
  float ssArray1[SS1];
  float ssArray2[SS2];
  printf("sum of squares test 1: enter %d numbers\n", SS1);
  for(int i = 0; i < SS1; ++i){
        scanf("%f",&ssArray1[i]);
  }
  printf("sum of squares = %.2f\n", sumSquares(ssArray1, SS1));
 
  printf("\nsum of squares test 2: enter %d numbers\n", SS1);
  for(int i = 0; i < SS1; ++i){
        scanf("%f",&ssArray1[i]);
  }
  printf("sum of squares = %.2f\n", sumSquares(ssArray1, SS1));
 
  printf("\nsum of squares test 3: enter %d numbers\n", SS2);
  for(int i = 0; i < SS2; ++i){
        scanf("%f",&ssArray2[i]);
  }
  printf("sum of squares = %.2f\n", sumSquares(ssArray2, SS2));
 
  // Sorted Tests------------------------------------

Why are you stuck? Please ask specific questions.

I don't know what to do, a tip to where to start or what to use would be nice. I am suppose to use the stdio and stdlib only.

So what does your sumSquares() look like?

Jim

something like this

Code:

---

float sumSquares(float a[], float b)
{
    int c;
    float total = 0;
    for(c = 0; c < b; ++c)
    {
        total = a[c]*a[c] + total;
    }
    return total;
}

---

is this correct? I am quite confused.

Not really the second parameter should be an int, not a float.

Jim

I think I got it, thanks!
