C#: Program to display certain values of the function
Write a C# Sharp program to display certain values of the function x = y2 + 2y + 1 (using integer numbers for y, ranging from -5 to +5).
Sample Solution:-
C# Sharp Code:
using System;
public class Exercise6
{
public static void Main()
{
int x, y; // Declare integer variables x and y
// Display the equation x = y² - 2y + 1
Console.WriteLine("x = y² - 2y + 1");
Console.WriteLine();
// Loop to calculate and display x for different y values (-5 to 5)
for (y = -5; y <= 5; y++)
{
// Calculate x using the equation x = y² - 2y + 1
x = y * y - 2 * y + 1;
// Display the value of y and the calculated value of x
Console.WriteLine(
"y = {0} ; x = ({0})² - 2*({0}) + 1 = {1}",
y, x);
}
}
}
Sample Output:
x = y² - 2y +1 y = -5 ; x=(-5)² - 2*(-5) +1 = 36 y = -4 ; x=(-4)² - 2*(-4) +1 = 25 y = -3 ; x=(-3)² - 2*(-3) +1 = 16 y = -2 ; x=(-2)² - 2*(-2) +1 = 9 y = -1 ; x=(-1)² - 2*(-1) +1 = 4 y = 0 ; x=(0)² - 2*(0) +1 = 1 y = 1 ; x=(1)² - 2*(1) +1 = 0 y = 2 ; x=(2)² - 2*(2) +1 = 1 y = 3 ; x=(3)² - 2*(3) +1 = 4 y = 4 ; x=(4)² - 2*(4) +1 = 9 y = 5 ; x=(5)² - 2*(5) +1 = 16
