Question

Suppose array1 is {1, 2, 3, 4, 5} and array2 is {2, 4, 8, 9, 10}. Show the accumulate, adjacent_difference, and partial_sum for array1. What is the inner product of array1 and array2? C++ language please

Answer 1

Code:-

#include<bits/stdc++.h>
using namespace std;
int main()
{ int sum = 0;//for
int array1[] = {1,2,3,4,5};//array1
int array2[] = {2,4,8,9,10};//array2
cout<<"Accumulate: "<<accumulate(array1,array1+5,sum)<<endl;//It returns the sum of all elements of array from 0th index to 4th index

int r[5];
partial_sum(array1,array1+5,r);//it returns the array of sum at each index from starting index
cout<<"The partial sum is: ";//sum from staring index to particular index
for(int i=0;i<5 ;i++)
cout<<r[i]<<" ";//display the returned array
cout<<endl;

int d[5];
adjacent_difference(array1,array1+5,d);//It returns the array of adjacent difference between elements of array
cout<<"The adjacent difference is: ";
for(int i=0;i<5 ;i++)
cout<<d[i]<<" ";
cout<<endl;

int init = 0;//product between corresponding element and sum them
//1x2+2x4+3x8+4x9+5x10
cout<<"Inner product: "<<inner_product(array1,array1+5,array2,init);//It returns the inner product of two vectors
return 0;
}
