What is An Introduction to Programming Through C++?

This course provides an introduction to problem-solving and programming using the C++ programming language. The topics include:

• Basic programming notions. Control flow, variables and assignments statements, conditional execution, looping, function calls including recursion. Arrays and structures. Elementary aspects of classes. Heap memory. 
• Program design. How human beings solve problems manually. Strategies for translating manual strategies to computer programs. Organizing large programs into units such as functions and classes. Introduction to assertions and invariants.
• Programming applications. Arithmetic on polynomials, matrices. Root finding. Sorting and searching. Design of editors and simulators, including graphical editors. Elementary animation. A rudimentary graphics system will be discussed.
• Standard Library of C++. The string, vector and map classes.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of the average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF THE AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Programming Assignment Answers:-

Q1. Write a program which takes the following as input: an integer N, an integer A, a sequence of N words which should be names of countries, a sequence of A words each of which is an attribute of a country (e.g. population, area, GDP), followed by a sequence of N*A real numbers (use double) where the iA+j th number gives the value of the jth attribute of the ith country, where 0<=j<A, 0<=i<N, followed by a sequence of pairs of words. The first word in each pair must be the name of a country, and the second an attribute. The program must then print the respective attribute of the respective country (e.g. population of India, GDP of China).

Code:-

#include<iostream>

using namespace std;
int main()
{
  int N,A;
  cin>>N>>A;
  string Country[N];for(int i=0;i<N;i++) cin>>Country[i];
  string Attribute[A];for(int i=0;i<A;i++) cin>>Attribute[i];
  float valArray[N*A];for(int i=0;i<N*A;i++) cin>>valArray[i];
  
  float ans[20]; int count=0;
  
  while (!cin.eof())
  {
    string _cntry,_attr;
    cin>> _cntry;
    cin>> _attr;
   
    int _cIndex=0;
    while (_cIndex<N)
    {
      if(Country[_cIndex]==_cntry)
      {break;}
      _cIndex++;
    }
    
    int _aIndex=0;
    while (_aIndex<N)
    {
      if(Attribute[_aIndex]==_attr)
                   {break;}
                   _aIndex++;
                   }
                   float _ans=valArray[(3*_cIndex)+_aIndex];
                   ans[count]=_ans;
                   count++;
                   }
                   for(int i=0;i<count-1;i++)
                   {
                     cout<<ans[i]<<endl;
                   }
                   return 0;
                   }

Q2. You are to write a function makeT that takes as input a set S of integers, and a target value T, and determines if any subset of the numbers in Sadds up to T. The function should be a modification of the function given in the quiz for printing all subsets of a set. The function should have thefollowing signature:

Code:-

bool makeT(int S[], bool selected[], int i, int n, int T)
{

    bool set[n + 1][T + 1];

    for (int i = 0; i <= n; i++)
        set[i][0] = true;

    for (int i = 1; i <= T; i++)
        set[0][i] = false;

    for (int i = 1; i <= n; i++)
    {
        for (int j = 1; j <= T; j++)
        {
            if (j < S[i - 1])
                set[i][j] = set[i - 1][j];
            if (j >= S[i - 1])
                set[i][j] = set[i - 1][j] || set[i - 1][j - S[i - 1]];
        }
    }

    return set[n][T];
}
