I have a snippet of code and for some odd reason I can not print it.
int[] answer = new int[15];
for (int i = 0; i < answer.Length; i++)
{
answer[i] = Console.ReadLine(answer);
}
It says that I can not do Console.ReadLine(answer);. How would I get this snippet of code to work?

ReadLineis for reading input not writing to the output. You needWriteLinefor that,Console.WriteLine(answer[i]);
Jump to PostAccording to the manual WriteLine() returns void, you can't assign that to
answer[i].

okay, so I tried that and my code looks like this now:
int[] answer = new int[5];
for (int i = 0; i < answer.Length; i++)
{
answer[i] = Console.WriteLine(answer[i]);
}
It still doesn't work, I still get an error. Did I do it wrong?
okay, so if that is the case, what would I have to do to get it to work?
int[] answer = new int[15];
for (int i = 0; i < answer.Length; i++)
{
Console.WriteLine(answer[i]);
}
Console.ReadLine();
but you didn t specify any values in the array so you ll get zeros here.
So what if I were to have an array and have the users populate it?
static void Main(string[] args)
{
int[] answer = new int[15];
for (int i = 0; i < answer.Length; i++)
{
answer[i] = Convert.ToInt32(Console.ReadLine()); // if string remove convert.toint32
}
Console.WriteLine("output is :");
for (int i = 0; i < answer.Length; i++)
{
Console.WriteLine(answer[i]);
}
Console.ReadLine();
}
Quick question, I have tried using your code for strings. It didn't work and I couldn't get it to work with Doubles either.
I switched the int into strings/double.
Strings:
static void Main(string[] args)
{
string[] answer = new string[15];
for (int i = 0; i < answer.Length; i++)
{
answer[i] = Console.ReadLine();
}
Console.WriteLine("output is :");
for (int i = 0; i < answer.Length; i++)
{
Console.WriteLine(answer[i]);
}
Console.ReadLine();
}
Doubles:
static void Main(string[] args)
{
double[] answer = new double[15];
for (int i = 0; i < answer.Length; i++)
{
answer[i] =Convert.ToDouble(Console.ReadLine());
}
Console.WriteLine("output is :");
for (int i = 0; i < answer.Length; i++)
{
Console.WriteLine(answer[i]);
}
Console.ReadLine();
}
Oh... so I see where I was making my mistakes. I was making my mistakes on line 6. I kept it similar to the one for integers.
Okay so for the double one, I tried to make a custom array size, sorry it was the best that I can call it. Basically what I am trying to do for the double array is to make the size of whatever the user wants.
So I tried to collect the size and it doesn't work.
int dNumber = 0.0;
Console.WriteLine("Type a number.");
line = Console.ReadLine();
dNumber = int.Parse(line);
int.TryParse(line, out dNumber);
I was using the above to collect the number to change the size of the array ( I hope I didn't paste the wrong one ).
Also, how do I apply an if statement to the string one, so in any case, if I input the word dog, the program would stop. I am currently beating myself on this one.
Sorry for the many questions, the last 2 arrays are not homework (the integer one was), I am just learning some techniques with arrays. But thanks for helping me as of so far.
To get a int, you can try something like this
int myNumber;
String input;
do {
Console.Write("Enter a number : ");
input = Console.ReadLine();
} while (Int32.TryParse(input, out myNumber) == false);
This will prompt the user over and over again for a number (integer number) until they enter one.
okay so how do combine that into this code:
static void Main(string[] args)
{
double[] answer = new double[15];
for (int i = 0; i < answer.Length; i++)
{
answer[i] =Convert.ToDouble(Console.ReadLine());
}
Console.WriteLine("output is :");
for (int i = 0; i < answer.Length; i++)
{
Console.WriteLine(answer[i]);
}
Console.ReadLine();
}
I got an error from trying to combine your source. for some odd reason, VS gave me an error saying that I can't change answer.Length into input.
I tried to end a program by using this, it doesn't work
double[] answer = new double[15];
for (int b = 0; b < answer.Length; b++)
{
answer[b] = Convert.ToDouble(Console.ReadLine());
}
Console.WriteLine("Inputs: ");
for (int b = 0; b < answer.Length; b++)
{
Console.WriteLine(answer[b]);
if (b = "stop")
{
Environment.Exit();
}
}
Console.ReadLine();
try double[] answer = new double[myNumber];
Is this what you are refering to:
int myNumber;
String input;
do
{
Console.Write("Enter a number : ");
input = Console.ReadLine();
}
while (Int32.TryParse(input, out myNumber) == false);
double[] answer = new double[mynumber];
for (int i = 0; i < answer.Length; i++)
{
answer[i] = Convert.ToDouble(Console.ReadLine());
}
Console.WriteLine("output is :");
for (int i = 0; i < answer.Length; i++)
{
Console.WriteLine(answer[i]);
}
Console.ReadLine();
I still can't collect numbers. It seems to skip the entire code until it reaches line 10.
Something like this should work:
int myNumber;
String input;
do
{
Console.Write("Enter a number : ");
input = Console.ReadLine();
} while (Int32.TryParse(input, out myNumber) == false);
double[] answer = new double[myNumber];
for (int b = 0; b < answer.Length; b++)
{
do
{
input = Console.ReadLine();
if (input == "q")
Environment.Exit(0);
} while (Double.TryParse(input, out answer[b]) == false);
}
Console.WriteLine("Inputs: ");
for (int b = 0; b < answer.Length; b++)
{
Console.WriteLine(answer[b]);
}
Console.ReadLine();
