Logical errors Example in C/C++ with solution

1. This program contain some logical errors.Find out these error and execute the correct code which shows following output:

#include <iostream>

using namespace std;

void get_input (int num1, int num2, int num3);

int  find_sum  (int& num1, int& num2, int& num3);

void display_output(int& num1, int& num2, int& num3, int& total);

int main()

{

 int num1, num2, num3, sum, total;

char answer;

do

{

get_input (num1, num2, num3);

sum= find_sum(num1, num2, num3);

display_output(num1, num2, num3, total);

cout << "Do you want to continue? (Enter Y/N)"<<endl;

cin >> answer;

}

while (answer == 'n' && answer =='N');

return 0;

}

void get_input(int a, int b, int c)

{

          cout << "Enter the first number" <<endl;

          cin >> a;

          cout << "Enter the second number" <<endl;

          cin >> b;

          cout << "Enter the third number" <<endl;

          cin >> c;

}

int find_sum(int& a, int& b, int& c)

{       

          return a+b+c;

}

void display_output(int& a, int& b, int& c, int& total)

{

  cout << "The sum of " << a <<","<< b <<","<< c << " is "

                     << total << endl;

}

SOLUTION :

#include <iostream>

using namespace std;

void get_input (int& num1, int& num2, int& num3);

int  find_sum  (int num1, int num2, int num3);

void display_output(int num1, int num2, int num3, int total);

int main()

{

 int num1, num2, num3, sum, total;

char answer;

do

{

get_input (num1, num2, num3);

sum= find_sum(num1, num2, num3);

display_output(num1, num2, num3,sum);

cout << "Do you want to continue? (Enter Y/N)"<<endl;

cin >> answer;

}

while (answer != 'n' || answer !='N');

return 0;

}

void get_input(int& a, int& b, int& c)

{

          cout << "Enter the first number" <<endl;

          cin >> a;

          cout << "Enter the second number" <<endl;

          cin >> b;

          cout << "Enter the third number" <<endl;

          cin >> c;

}

int find_sum(int a, int b, int c)

{       

          return a+b+c;

}

void display_output(int a, int b, int c, int total)

{

  cout << "The sum of " << a <<","<< b <<","<< c << " is "

                     << total << endl;

}
