Question

Write a function in the C++called summary that takes as its parameters an input and output file. The function should read two integers find the sum of even numbers, the sum of odd numbers, and the cumulative product between two values lower and upper. The function should return the sum of even, odd, ad cumulative product between the lower and upper values.

Please write program in C++.

Answer 1

CODE:

#include <iostream>
#include <fstream>

using namespace std;

void summary(string filename,string filename1){
fstream file,file1;
//opening both the input and output files
file.open(filename.c_str());
file1.open(filename1.c_str(),ios::out);
int a,b;
//getting the two numbers from the input file
file>>a;
file>>b;

int oddSum = 0,evenSum = 0,cumprod = 1;
for(int i=a;i<=b;i++){
//finding the sum of even and odd numbers separately
if(i%2 == 0){
evenSum += i;
}else{
oddSum += i;
}
//finding the cumulative product in the range
cumprod *= i;
}
file1<<"Sum of even numbers in the range "<<a<<" to "<<b<<" is: "<<evenSum<<endl;
file1<<"Sum of odd numbers in the range "<<a<<" to "<<b<<" is: "<<oddSum<<endl;
file1<<"Cumulative product of numbers in the range "<<a<<" to "<<b<<" is: "<<cumprod<<endl;
//closing the files
file.close();
file1.close();
}
int main() {
//calling the function
summary("input.txt","output.txt");
cout<<"Output File written"<<endl;

return 0;
}
