Question

Write a C++ program using user defined functions that will read in the lengths of two side of a right triangle and then calculate the length of the hypotenuse. The program should do this twice.

The program should the following user defined functions:

Function readA will read in a value for side A from the user and return it to main. (it will not receive any input data from main)

Function readB will read in a value for side B from the user and return it to main. (it will not receive any input data from main)

Function calchyp will receive the values of A and B from main, calculate the hypotenuse and return that value to main.

Print the results to the console screen in a table containing all three columns (a, b, and c).

           

Test the program with a=3, b=4 and a=6, b=8.

Answer 1

C++ program:

#include<iostream>

#include<cmath>

using namespace std;

int readA() //function that reads value of a from user

{

int a;

cin>>a;

return a;

}

int readB() //function that reads value of b from user

{

int b;

cin>>b;

return b;

}

int calcHyp(int a,int b) //function to calculate hypotenuse and return the value

{

int c;

c = a*a + b*b; //formula (hypotenuse)² = a² + b²

c = sqrt(c); //=>hypotenuse = sqrt(a² + b²)

return c;

}

int main()

{

int a,b,c,i;

for(i=0;i<2;i++)

{

cout<<"Enter value of side a :";

a = readA();

cout<<"Enter value of side b :";

b = readB();

c = calcHyp(a,b);

cout<<"a b c"<<endl; //printing the values of a, b, c in a tabular format

cout<<a<<" "<<b<<" "<<c<<endl;

}

return 0;

}

output :
