Question

i need help determining the output for these problems

1. For ( int count = 1; count < 30; count+=9)

Cout << (3 + count) << “ “ ;

________________

2. int I = 1;

       While ( I <= 10)

        {

            If ( I > 5 && i ! = 9)

                   Cout << ‘x’ ;

             I++;

        }

      ____________________

3. double a [3] = {1.1, 2.2, 3.3};

        cout << a [0] << “ “ << a [1] << “ “ << a[2] << endl;

       a[1] = a[2];

       cout << a [0] << “ “ << a [1] << “ “ << a [2] << endl;

_________________________

4. Char Mystring[6]=”Hello”;

Char Name{10];

Strncpy(Name,Mystring,,2);

Cout<

Cout<

__________________________

5. cout << “ enter a line of input : \n”;

char next;

Do

{

       cin.get(next);

        cout << next;

} while ( (! Isdigit(next) ) && (next 1 = ‘\n’) );

Cout << “

If the dialogue begins as follows, what will be the next line of output?

Enter a line of output;

I’ll see you at 10:30 AM.

6. char next;

     int count = 0;

cout << “ Enter a line of input: \ n”;

cin. Get (next);

While (next != ‘\n\ )

{

      If ((count % 2) ==0)

           cout << next;

       Count ++;

        cin.get(next);

}

1 Ans)

For ( int count = 1; count < 30; count+=9)

Cout << (3 + count) << “ “ ;

Initally,

count = 1

print 3+count = 4

count += 9 => count = 10

print 3+count = 13

count += 9 => count = 19

print 3+count = 22

count += 9 => count = 28

print 3+count = 31

count += 9 => count = 37

since count is greater than 30 exit the loop

2 Ans)

int I = 1;

While ( I <= 10)

       {

            If ( I > 5 && i ! = 9)

                   Cout << ‘x’ ;

             I++;

        }

Initally, I = 1

Since I <= 10, get into loop

I > 5 is false

Since I <= 10, get into loop

I > 5 is false

I++ => I = 2

Since I <= 10, get into loop

I > 5 is false

I++ => I = 3

Since I <= 10, get into loop

I > 5 is false

I++ => I = 4

Since I <= 10, get into loop

I > 5 is false

I++ => I = 5

Since I <= 10, get into loop

I > 5 is false

I++ => I = 6

Since I <= 10, get into loop

I > 5 and I != 9 are true so print(x)

I++ => I = 7

Since I <= 10, get into loop

I > 5 and I != 9 are true so print(x)

I++ => I = 8

Since I <= 10, get into loop

I > 5 and I != 9 are true so print(x)

I++ => I = 9

Since I <= 10, get into loop

I > 5 is true and I != 9 is false

I++ => I = 10

  

Since I <= 10, get into loop

I > 5 and I != 9 are true so print(x)

I++ => I = 11

Since I <= 10 false terminate loop

3 Ans)

double a [3] = {1.1, 2.2, 3.3};

        cout << a [0] << “ “ << a [1] << “ “ << a[2] << endl;

       a[1] = a[2];

       cout << a [0] << “ “ << a [1] << “ “ << a [2] << endl;

print a[0] which is 1.1 ,a[1] which is 2.2, a[2] which is 3.3

now a[1] = a[2] means a = {1.1,3.3,3.3}

print a[0] which is 1.1 ,a[1] which is 3.3, a[2] which is 3.3

4 Ans)

strncpy copies one string to another with mentioned number of characters here we are copying 2 characters of Mystring which is He so, name contains "He"

5 Ans)

The input is taken until the character is not a digit or new line here in input it prints up to it gets 1 in 10:30

The output is : I'll see you at 1

6 Ans)

It takes the string character by character with 0-indexing and prints even indexed characters
