Question

My friend and I need help with our project. The directions are "Write a C# program to count the number of negative numbers in a sequence of numbers the user inputs. In this solution, before reading the numbers, ask the user to input how many numbers will be input. For Example: For input 32, 76, -12, 49, -11, and -3 the output should be that there are three negative numbers.

So far we have

Console.Write("How many numbers will you be inputting?: ");
int num = int.Parse(Console.ReadLine());
for (int i = 0; i < num; i++)
{
Console.Write("PLease enter a number: ");
int x = int.Parse(C

Answer 1

Here it is in Python. Considering what you have already, you should be able to adapt this into C#. Basically you just need to initialize a counter outside the for to 0 and increment it if inputs are less than 0. Then display result when for loop terminates.

>>> def count_negative():
num = int(input("How many?: "))
negs = 0
for i in range(num):
nums = int(input("Enter number: "))
if nums < 0:
negs += 1
print(str(negs) + " negs entered.")


>>> count_negative()
How many?: 6
Enter number: 32
Enter number: 76
Enter number: -12
Enter number: 49
Enter number: -11
Enter number: -3
3 negs entered.

Answer 2

Here is the solution you are looking for:

Console.Write("How many numbers will you be inputting?: ");
int num = int.Parse(Console.ReadLine());
int count = 0;

for (int i = 0; i < num; i++) {
Console.Write ("PLease enter a number: ");
int x = int.Parse (Console.ReadLine ());
if (x < 0) {
count++;
}
}
Console.WriteLine ("There are {0} negative numbers.", count);
