Question

Write a fragment of code that reads in a header value from the standard input and then reads in that many integers (also from standard input) and prints their sum to standard output (for loops, header values, accumulators, basic arithmetic). Declare any variables you use.

part b

Objects of the Calculator class require no additional information when created. Define an object named calc, of type Calculator.

Answer 1

a) Code fragment:

  
   int *p;
   cin >> header_value;
   p = new int[headr_value];
   for (int i = 0; i<header_value; i++)
       cin >> p[i];
   int sum = 0;
   for (int i = 0; i<header_value; i++)
       sum = sum + p[i];
   cout << sum;

b) Calculator calc;
