Find two syntax errors in the following program:
#include <iostream>
using namespace std;
int area(int length, int width = 0);
int main()
{
int length, width;
// for rectangle use both arguments
cout << "Enter length and width of a rectangle" <<
endl;
cin >> length >> width;
cout << "The area is " << area(length, width) << endl;
// for square, only need first argument
cout << "Enter side of a square" << endl;
cin >> length;
cout << "The area is " << area(length) << endl;
return 0;
}
int area(int length, int width = 0);
{
if ( width == 0 )
return length * length;
return length * width;
}

Write following program using Switch statement. #include <iostream> using namespace std; int main() int number; cout << "Enter an integer cin >> number; if (number > B) cout << You entered a positive integer: " << number << endl; else if (number (8) cout<<"You entered a negative integer: " << number << endl; cout << "You entered e." << endl; cout << "This line is always printed." return 0;
C++ Fix the errors in the following code. (Not all errors are syntax related) #include <iostream> using namespace std; int main() { //Part A int numA numA = 10; cout << numA << end; /* Part B */*/ int numB = numA; cin >> usrInput; int usrInput = 0; numB = numB + usrInput; cout << numB <"/n"; /* Part C */ int numC = 10000000000; cout << numC << endl; return 0; }

Add comments on this Fibonacci C++ program in detail. #include <iostream> using namespace std; int fib(int n){ int a = 0,b = 1,c; if(n == 0 || n == 1){ return n; } while(n>2){ c = b + a; a = b; b = c; n--; } return c; } int main(){ int n; cout<<"Enter n: "; cin>>n; int result = fib(n); cout<<"Fib("<<n<<") = "<<result<<endl; return 0; }
Write the missing statements for the following program. #include <iostream> using namespace std; int main(void) { int Num1; cout << "Enter 2 numbers: "; cin >> Num2; if (Num1 < Num2) cout << "Smallest number is " << Num1; else cout << "Smallest number is " << Num2; return 0; }
This program illustrates dynamic variables #include <iostream> using namespace std; int main () { int *p1; p1 = new int; // Variables created using the new operator are called dynamic variables cout << "Enter an integer \n"; cin >> *p1; *p1 = *p1 + 7; cout << << "Your input + 7 = " << *p1 << endl; delete p1; // Delete the dynamic variable p1 and return the memory occupied by p1 to...
#include <iostream> #include <string> using namespace std; int main() { int number; int sum = 0; while(true) { cout << "Please enter a number between 1 and 11: "; cin >> number; if (number >= 1 && number <= 11) { cout << number << endl; sum = sum + number; //only add the sum when number is in range: 1-11, so add wthin this if case } else { cout << number << endl; cout << "Out of range;...
Consider the following C++ program: #include <iostream> #include <cstdlib> using namespace std; int main int n =0; int i = 0; cout << "Please enter a strictly positive number:"; cin >> n if (n <= 0) exit(EXIT_FAILURE) while (n > 1) n-n/2; i << endl; cout"Output:" return 0; Answer the following questions: What is the output of the program for each of the following values of n: -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9? What does...
what is the output for the following code? explain the steps. /*#include <iostream> using namespace std; int f(int &i) { i = 10; return(5 * i); } int main() { int n = 5; f(n); cout << n << "\n"; return 0; } #include <iostream> using namespace std; int sub1(int n) { n--; return n; } int main() { int m = 10; for(int j = 0; j < 10; j++) m -= sub1(j); cout << m << "\n"; return...
Find and fix errors #include <iostream> #include <cstdlib> #include <ctime> using namespace std; const int MIN = 1; const int MAX = 10; int getRandom(int low, int high); int main() { int random_num = 0; int player_num; int tries; int seed = static_cast<int>(time(0)); bool guessed = false; srand(seed); // call the getRandom function below tries = 4; while ( tries > 0 && !guessed ) { cout << "Enter a number within the range 1 to...
