Generally there are four data types, each of which can be signed or unsigned.Write names of all four data types.

If v is an identifier of int type and is holding value 255. Is the following statement correct?
char code = v;

Do you see any similarity between a typedef name and a reference name? If yes, what is it?

Which value of x will be printed in following case and why?
int x=9;
void main()
{
  int x = 10;
  cout<<x;
}

In the following program:
i) How many times will the while loop run?
ii) What would be the last value of A displaced out?
#include<iostream.h>
void main()
{
      int A=10;
      while(++A<15)
      { 
          cout<<A++;
     }
}

Declare a structure applicant to store the following data: Applicant name, Code number, Data of birth (day,month,year)

An unsigned int can be twice as large as the signed int. Explain how?

Write the output of the following program.
Void main()
{
     int x=5, y=5;
     cout<<x--;   
     cout<<",";
     cout<<--x;
     cout<<",";
     cout<<y--<<","<<--y;
}

What is the function of typedef in C++ Also, give a suitable C++ code to illustrate it?

What is the benefit of using default parameter/ argument in a function? Give a suitable example to illustrate it using C++ code.

Rewrite the following program after removing the syntactical errors,if any.Underline each correction.
#include<iostream.h>
void main()
{
    struct STUDENT
      {
         char stu_name[20];
         char stu_sex;
         int stu_age=17;
     }student;
     gets(stu_name);
     gets(stu_sex);
}

To show how the statements are being executed sequentially with the help of addition of two integers.

To show the use of if statement.

To know the use of if-else statement.

To print the numbers 0 to 10 with the help of for loop.

To show the use of goto statement.

To show the working of exit statement.

Write the following program execute successfully? If not, state the reason(s).
#include<stdio.h>
void main()
{
    int x, sum=0;
    cin<<n;
    for( X=1, x<100, x+=2)
     if x%2==0
       sum +=x;
cout>>"sum=">>sum;
}

To illustrate the concept of passing entire structure as function argument using pass by reference.

List the output of the program below.In other words, everytime there is a cout statement, list the values that will appear on the screen.
#include<iostream.h>
#include<conio.h>
void main()
{
 clrscr();
 for(int i=1;i<3;i++)
   for(int j=1;j<=5;j+=2)
      cout<<i<<"*"<<j<<"="<<i*j<<endl;
double a=1;
while(a<32)
      a*=2;
cout<<"a="<<a<<endl;
i=8,j=3;
int k=i/j;
double b=i/j;
double c=((double)i/(double)j);
cout<<"Now k="<<k<<", b="<<b<<", c="<<c<<endl;
getch();
}
