Answer:
I did this in C# & Java
Explanation:
C#:
public static void Main(string[] args)
{
int input = Convert.ToInt32(Console.ReadLine());
Multiply(input);
}
public static int Multiply(int input)
{
int ans = 0;
for(int i =1; i<=10; i++)
{
ans = i*input;
Console.WriteLine(i + "*" + input + "=" + ans);
}
return ans;
}
Java:
public static void main(String[] args)
{
Scanner myObj = new Scanner(System.in);
int input = Integer.parseInt(myObj.nextLine());
Multiply(input);
}
public static int Multiply(int input)
{
int ans = 0;
for(int i =1; i<=10; i++)
{
ans = i*input;
System.out.println(i + "*" + input + "=" + ans);
}
return ans;
}
