float array into function

[T4l0n]

so i made this with int which works properly:

#include <iostream>
using namespace std;

int blue(int array[], int num);

int main (){
    int red [3]={2,9,8};
    cout << "the sum of the numbers in the array is: " << blue(red,3) << endl;
    system("pause");
    return 0;
}

int blue(int array[], int num){
    int sum=0;
    for(int x=0;x<num;x++){
            sum+=array[x];
            }
    return sum;
}

then i wanted to make one with decimals so i used float but i can't manage to make it work

#include <iostream>
using namespace std;

float blue(float array[],int num);

int main (){
    float red [3]={2.5,9.6,8.7};
    cout << "the sum of the numbers in the array is: " << blue(red,3) << endl;
    system("pause");
    return 0;
}

float blue(float array[],int num){
      float sum=0;
      for(float x=0;x<num;x++){
                sum+=array[x];
                }
      return sum;
      }

x should still be an int.

EDIT: (thanks to Peter87)

float blue(float array[],int num){
      float sum=0;
      for(int x=0;x<num;x++) //To access element to array you need integer!
                sum+=array[x];
      return sum;
}

For loops use int

for loops can use any types. The problem is that you can't use floating point numbers as an index to an array. It has to be an integer.

CRAP :D i knew something i said was wrong.
^agreed. Pass on

Sorry, it's just me being pedantic. If you think I'm a jackass, please say so.
