double n1,n2,n3,sum;

System.out.println("Enter three decimal numbers:");

n1 = in.nextDouble();

n2 = in.nextDouble();

Answer 2

Below are the program in c language for the above question:

Explanation:

#include <stdio.h>

int main()

{

   float a,b,c;// variable declaration of float type which store decimal value

   scanf("%f %f %f",&a,&b,&c);// take three input as decimal value

   printf("%f",a+b+c);// prinnt the addition of decimal value

   return 0;

}

Output:

• If the user inputs 2.3, 3.2 and 4.5 then the output is 10.000000
• If the user inputs 2.3, 2.3 and 2.3 then the output is 6.900000

In the above program, scanf() is used to take input of three float variable. It is because there is %f, which represents the value in float. The printf() is used to print the value.
