C++ code:

#include <iostream>

void inp_arr(double *arr,const unsigned int size){

for(int i = 0; i < size; i++){

 std::cout << "arr[" << i << "]: ";

 std::cin >> arr[i];

}

}

void print_arr(double *arr,const unsigned int size){

for(int i = 0; i < size; i++){

 std::cout << arr[i] << "\t";

}

std::cout << std::endl;

}

double sum_arr(double *arr,const unsigned int size){

double sum = 0;

for(int i = 0; i < size; i++){

 sum += arr[i];

}

return sum;

}

int main(){

setlocale(LC_ALL , "Ukrainian");

const unsigned int size = 7;

double arr[size];

inp_arr(arr,size);

print_arr(arr,size);

std::cout << "Сума елементiв = " << sum_arr(arr,size) << std::endl;

return 0;

}
