main_program{
int n; cin >> n;
double i= BlankA, term = BlankB, result = BlankC;
repeat(n){// On tth entry, t=1..n
// i=t-1, term=1/t!
// result=1/0!+..+1/(t-1)!
BlankD
}
cout << result << endl;
}
1)what is BlankA?
2)what is BlankB?
3)what is BlankC?
4)Which of the following will be correct in BlankD?
i = i + 1; term = term / (i+1); result = result + term;
result = result + term; i = i + 1; term = term / (i+1);
i = i + 1; result = result + term; term = term / (i+1);
term = term / (i+1); result = result + term; i = i + 1;

[solved] – Question 93042
Consider the code below for calculating the value of e (Euler’s number/constant used in mathematics). It solves the same problem as discussed in the lecture but it does it differently. In the ith iteration it calculates the value of 1/i! and adds it to the result.
main_program{
int n; cin >> n;
double result = 0;
int i=__;
repeat(n){
// calculate 1/i!
int t=1;
double term = 1;
repeat(i){
term = term/t;
t = t + 1;
}
result = result + term;
i = i + 1;
}
cout << result << endl;
}
What should i be initialized to?
