Question

Read each question carefully before you answer. For full credit trace and show that value of all the isted variables and walkthrough your code where indicated. Use the function names provided to complete the question and read the associated descriptions to understand how the function works. Your program must use functions, and unless otherwise indicated assume file input.

2-Create a struct to hold a fractio Suct to hold a fraction. The struct should have an integer numerator and ger denominator member. Write a function called addFractions that takes born fractions, adds them together. Return the result to the calling function.

c++ programming

Answer 1

#include<iostream>
using namespace std;

//struct fraction
typedef struct fraction {
   //numerator and denominator
   int numerator;
   int denominator;
} Fraction;

Fraction addFraction(Fraction f1, Fraction f2) {
   /*
       f1 = a/b
       f2 = c/d
      
       f1 + f2 = a/b + c/d = (a.d + b.c) / bd
   */
  
   Fraction f3;
   f3.numerator = f1.numerator*f2.denominator + f2.numerator*f1.denominator;
   f3.denominator = f1.denominator*f2.denominator;
  
   return f3;  
}

//helper function to print content of strcuct Fraction
void printFraction(Fraction f) {
   cout << "Numerator: " << f.numerator;
   cout << "\nDenominator: " << f.denominator << endl;
}

int main() {
  
   //declaring and initialising two fractions f1, f2
   Fraction f1, f2;
   f1.numerator = 5;
   f1.denominator = 7;
  
   f2.numerator = 3;
   f2.denominator = 5;
  
   cout << "Fraction f1: " << endl;
   printFraction(f1);
  
   cout << "Fraction f2: " << endl;
   printFraction(f2);
  
   Fraction f3 = addFraction(f1, f2);
   cout << "Fraction f1+f2: " << endl;
   printFraction(f3);
  
}
