Question 1
What happens if characters 'w', 'o', 'r', 'l' and 'd' are entered as input?
#include <iostream>
#include <string>
using namespace std;
int main()
{
string s1 = "Hello";
string s2;
getline( cin, s2 );
cout << s1 + s2;
return( 0 );
}
Question 2
What happens when you attempt to compile and run the following code?
#include <iostream>
using namespace std;
void fun(int*);
int main()
{
int i=2;
fun(&i);
cout<<i;
return 0;
}
void fun(int *i)
{
*i = *i**i;
}
Question 3
Point out an error in the program.
#include <iostream>
using namespace std;
int main()
{
const int x=1;
int const *y=&x;
cout<<*y;
return 0;
}
Question 4
If there is one, point out an error in the program
#include <iostream>
using namespace std;
int main()
{
int i=1;
for(;;)
{
cout<<i++;
if(i>5)
break;
}
return 0;
}
Question 5
What happens when you attempt to compile and run the following code?
#include <cstdlib>
#include <iostream>
using namespace std;
float* sum(float a,float b);
float* sum(float a,float b)
{
float *f = new float;
*f = a+b;
return f;
}
int main()
{
float a,b,*f;
a = 1.5; b = 3.4;
f = sum(a,b);
cout<<*f;
return 0;
}
