C++ double compu teInterest(double principal, double rate, i nt months) this fun

Question

C++

double compu teInterest(double principal, double rate, i nt months) this function is named computelnterest; it returns a double for output, and receives two doubles and an int for input. create a double variable named totalInterest, and set it equal to 0.0 double tota!Interest = 0.0; next create a for-loop that starts an int variable(named i) at 0, iterates while i is less than 2. 3. months, and increments i by 1 for the post-action. Here is the for-loop structure for (initial state; condition; post-action)

Explanation / Answer

#include<iostream>
using namespace std;

// step1
double computeInterest(double principal, double rate, int month)
{
// step 2
double totalInterest = 0.0;
  
// step 3
for(int i=0;i<month;i++)
{
// step 4
double interest = principal * rate;
  
// step 5
principal += interest;
totalInterest += interest;
}
  
// step 6
return totalInterest;
}

main()
{
// sample run
cout << computeInterest(100, 0.05, 2);
}

#include<iostream>
using namespace std;

// step1
double computeInterest(double principal, double rate, int month)
{
// step 2
double totalInterest = 0.0;
  
// step 3
for(int i=0;i<month;i++)
{
// step 4
double interest = principal * rate;
  
// step 5
principal += interest;
totalInterest += interest;
}
  
// step 6
return totalInterest;
}

main()
{
// sample run
cout << computeInterest(100, 0.05, 2);
}

Sample Output: 10.25
