Triangular Computation in C++

Question

Triangle Computation

Concepts tested: Mathematical computation, formatting output

  

Write a program that:

 1) Reads in the length of 2 sides of a triangle as double (do NOT print out any prompts/instructions for the user)

 2) Computes the length of the 3rd side using the Pythagorean theorem (a^2 + b^2 = c^2, where a, b, and c, are the side lengths)

 3) Presents the length of the 3rd side with exactly 2 digits after the decimal point

 Example Input / Output:

  

 2.3658

 3.36954

 4.12



Code:

#include <iostream>

// OTHER INCLUSIONS

using namespace std;​

int main()

{

   //YOUR_CODE

}

Answer 1

#include <iostream>

#include <math.h>

using namespace std;

int main(int argc, char **argv) {

double side1, side2;

cin >> side1;

cin >> side2;

printf("%0.2f\n", sqrt(side1*side1 + side2*side2));

return 0;

}
