Question

Question-5 [5 marks] Consider the definition of general summation of numbers between two values as describe in lecture: (define (sum term a next b) (if (> a b) ( (term a) (sum term (next a) next b)))) Given helper fiunctions inc and identity one can, for example, define a function that sums all integers from a to b: (define (inc x) (+ x 1)) (define (identity x) x) (define (sum-integers a b) (sum identity a inc b)) The general sum procedure above generates a linear recursive process. Rewrite it as an iterative process.

Explanation / Answer

#include <bits/stdc++.h>

using namespace std;

int inc(int x)

{

return x+1;

}

int identity(int x)

{

return x;

}

int sum_integers(int a, int b)

{

int sum=0;

while(a<=b)

{

sum=sum+identity(a);

a=inc(a);

}

return sum;

}

int main()

{

int a,b,sum=0;

cout<<"Enter range 'a' and 'b' : "<<endl;

cin>>a>>b;

sum=sum_integers(a,b);

cout<<"Sum = "<<sum<<endl;

return 0;

}
