C++ I have two questions [closed]

Please h开发者_如何学Pythonelp me with my homework:

• There is an array a [20] of float numbers, Enter number in the array. Find the sum of negative number.
• Enter 10 integer numbers in the array a [10]. Find the sum of positive numbers.

General psuedo-code to get you in the right direction for finding the sum of positive numbers in the array:

float result = 0;
for(int i = 0; i < array_length; i++)
{
  if(array[i] > 0)
    result = result + array[i];
}

For the sum of negative numbers, just switch the if-statement. Of course, this isn't exactly C++ code, but I think you can make it work from here pretty easily enough. :)

You access a value with the [] operator, so for instance, accessing the first value from the array a, you write a[0].

After that it is a matter of using for to iterate over the numbers.
