Question

I have this code, but I need a flowchart that shows how my program works, and the inputs and outputs???

#include <iostream>
#include <cmath>
using namespace std;
int fact(int n)
{
int i;
int c = 1;
for(i=1; i<=n; i++)
{
if(n==0)
c = 1;
else
c = c*i;
}
return c;
}
double ex(int n,double x)
{
int i;
double c = 0.0;
for(i=0; i<=n; i++)
{
c = c + (double)(pow(x,i)/ (double)fact(i));
}
return c;
}
double sinx(int n,double x)
{
int i;
double c = 0.0;
double xInRadian = (3.14 / 180.0)* x;
for(i=0; i<=n; i++)
{
if(i%2==0)
c = c + (double)(pow(xInRadian,2*i+1)/double(fact(2*i+1)));
else
c = c - (double)(pow(xInRadian,2*i+1)/double(fact(2*i+1)));

}
return c;
}
double cosx(int n,double x)
{
int i;
double c = 0.0;
double xInRadian = (3.14 / 180.0)* x;
for(i=0; i<=n; i++)
{
if(i%2==0)
c = c + (double)(pow(xInRadian,2*i)/double(fact(2*i)));
else
c = c - (double)(pow(xInRadian,2*i)/double(fact(2*i)));

}
return c;
}

int main()
{
double x;
int n;
cout<<"Enter the value of x: ";
cin>>x;
cout<<"\nEnter the number of terms to be executed: ";
cin>>n;
cout<<"\ne to power of x = "<<ex(n,x);
cout<<"\nsin("<<x<<") = "<< sinx(n,x);
cout<<"\ncos("<<x<<") = "<< cosx(n,x);
return 0;
}

Answer 1

Main Function:

flowchart for Function Fact

Flowchart for Function exp

Flowchart for Sinx function

Flowchart for cosx function

Input: 12

Output:
