Question

Expressions Write a console program that prompts the user for 3 double precision floating point values input1, input2, input3. Have the program compute and display the following values. the sum of input1, input2, input3 the average of input1, input2, input3 the log2 of input1 To access the built-in function log2 -- log2(X) computes the base 2 logarithm of X, you need to include the header at the top of your code.

Answer 1

See Explaination

Step-by-step explanation:

#include <iostream>

#include <cmath>

using namespace std;

int main()

{

float input1, input2, input3;

float sum=0.0, avg, l;

cout<<"enter the value for input1: ";

cin>>input1;

cout<<"enter the value for input2: ";

cin>>input2;

cout<<"enter the value for input3: ";

cin>>input3;

sum=input1+input2+input3;

cout<<"sum of three numbers: "<<sum<<endl;

avg=sum/3;

cout<<"average of three numbers: "<<avg<<endl;

l=log2(input1);

cout<<"log2 value of input1 number: "<<l;

return 0;

}

output:

enter the value for input1: 4

enter the value for input2: 5

enter the value for input3: 6

sum of three numbers: 15

average of three numbers: 5

log2 value of input1 number: 2
