Ans:
#include
#include
using namespace std;
int main()
{
int num; cout << "Please enter integer:- "; cin >> num;
if ( num > 0) { cout << "You have entered a +ve integer:- " << num << endl; } else if (num<< "You have entered a -ve integer:- " << num << endl; } else { cout<<
#include
using namespace std;
int main()
{
int num, i = 1, factorial = 1;
cout << "You are in factorial program of C++. Please enter a +ve integer:- "; cin >> num; while ( i <<< num <<< factorial; getch(); return 0;
}
Q3) Write a program of do-while program C++?
Ans:
#include

using namespace std;
int main()
{
float num, sum = 0.0; do { cout<>num; sum += num; } while(num != 0.0);
cout<<
