The part ""The sum of positive input is:" and "The sum of negative input is:" are not working there's no answer showing what could be the solution? btw this an 11th grade question
int i, num, sum = 0;
Console.Write("\nInput the number of elements to be stored in the array :");
num = Convert.ToInt32(Console.ReadLine());
for (i = 0; i < num; i++)
{
Console.Write("Elements - {0}:", i, num);
array[i] = Convert.ToInt32(Console.ReadLine());
}
Console.Write("The positive inputs are :");
for (i = 0; i < num; i++)
{
if (array[i] >= 0)
{
Console.Write(array[i] + ",");
array[i]++;
}
}
Console.Write("\nThe sum of positive input is :");
for (i = 0; i < num; i++)
{
if (array[i] >= 0)
{
sum += array[i];
}
}
Console.Write("\nThe negative inputs are :");
for (i = 0; i < num; i++)
{
if (array[i] < 0)
{
Console.Write(array[i] + ",");
array[i]++;
}
}
Console.Write("\nThe sum of negative input is :");
for (i = 0; i < num; i++)
{
if (array[i] < 0)
{
sum += array[i];
}
}
Special thanks to Sir Usama And Sir Drag and Drop
int[] array = new int[100];
int i, num, sum = 0;
Console.Write("\nInput the number of elements to be stored in the array :");
num = Convert.ToInt32(Console.ReadLine());
for (i = 0; i < num; i++)
{
Console.Write("Elements - {0}:", i, num);
array[i] = Convert.ToInt32(Console.ReadLine());
}
Console.Write("The positive inputs are :");
for (i = 0; i < num; i++)
{
if (array[i] >= 0)
{
Console.Write(array[i] + ",");
}
}
Console.Write("\nThe sum of positive input is :" );
for (i = 0; i < num; i++)
{
if (array[i] >= 0)
{
sum += array[i];
}
}
Console.Write(sum);
sum = 0;
Console.Write("\nThe negative inputs are :");
for (i = 0; i < num; i++)
{
if (array[i] < 0)
{
Console.Write(array[i] + ",");
}
}
Console.Write("\nThe sum of negative input are :" );
for (i = 0; i < num; i++)
{
if (array[i] < 0)
{
sum += array[i];
}
}
Console.Write(sum);
First, you don't initialize your array after you read the array length from user input. You should have:
int[] array;
Console.Write("\nInput the number of elements to be stored in the array :");
num = Convert.ToInt32(Console.ReadLine());
array = new int[num];
Second, you are using the same sum
variable for both positive and negative calculation (without resetting it in between). You can use two separate variables for these two computations:
int i, num, posSum = 0, negSum = 0;
Third, as Drag and Drop mentioned in the comment, you don't need that array[i]++;
, since it modifies the elements of the array.
Fourth, as Usama Aziz mentioned in the comment, you don't have a Console.Write
where you print the results.
The final solution should look like this:
static void Main(string[] args)
{
int i, num, posSum = 0, negSum = 0;
int[] array;
Console.Write("\nInput the number of elements to be stored in the array :");
num = Convert.ToInt32(Console.ReadLine());
array = new int[num];
for (i = 0; i < num; i++)
{
Console.Write("Elements - {0}:", i, num);
array[i] = Convert.ToInt32(Console.ReadLine());
}
Console.Write("The positive inputs are :");
for (i = 0; i < num; i++)
{
if (array[i] >= 0)
{
Console.Write(array[i] + ",");
}
}
Console.Write("\nThe sum of positive input is :");
for (i = 0; i < num; i++)
{
if (array[i] >= 0)
{
posSum += array[i];
}
}
Console.Write(posSum);
Console.Write("\nThe negative inputs are :");
for (i = 0; i < num; i++)
{
if (array[i] < 0)
{
Console.Write(array[i] + ",");
}
}
Console.Write("\nThe sum of negative input is :");
for (i = 0; i < num; i++)
{
if (array[i] < 0)
{
negSum += array[i];
}
}
Console.Write(negSum);
}
Good luck on your exam!
