C# Program using Functions and loops
C# Program using Functions
Program Statement:
Write a function which takes one value as parameter and display the sum of digits in the value. e.g. if user has passed 125 then function will print 1+2+5 = 7
Solution:
class _sum
{
long n, i, sum = 0;
public void add(long n)
{
for (i = n; i != 0; i = i / 10)
{
sum = sum + i % 10;
}
Console.WriteLine("\n\t\tSum of digits is : {0}", sum);
}
public void input()
{
Console.Write("\n\t\tEnter desired digit : ");
n = Convert.ToInt64(System.Console.ReadLine());
add(n);
}
}
C# Program using Two argument passing function
C# Program using Two argument passing function
Program Statement:
Write a function which takes two values n1 and n2 as arguments and multiply the n1 by itself n2 times i.e. calculate n1n2 and then return the result to main function which will display the result.
Solution:
class power_fun
{
double x;
public
power_fun()
{
x = 1;
}
double power(int a,int b)
{
for (int i = 1; i <= b; i++)
{
x = x * a;
}
return x;
}
static void Main(string[] args)
{
power_fun p = new power_fun();
int n1, n2;
double result;
Console.Write("Enter 1st Value: ");
n1 = Convert.ToInt32(Console.ReadLine());
Console.Write("Enter 2nd Value: ");
n2 = Convert.ToInt32(Console.ReadLine());
result= p.power(n1, n2);
Console.WriteLine(n1+"^ "+ n2+" = "+ result);
Console.ReadLine();
