ASSIGNMENT # 02
1. If you want the user to input an integer value into your program for a
variable named number, what are two lines of code you could write to ask
the user to do it and to input the value into your program?
Answer:
cout<<”Enter the integer value:”;
Cin>>number;
2. What is \n called and what purpose does it serve?
Answer:
In C++ a term called escape sequence. \n is a type escape sequence which is used to
create new line in the program. \n always write in double quotations in the program. We can
also use endl instead of \n.
e.g. cout<<”Zubaib”<<”\n”;
3. How would you write?
Cout<< "Hello, ";
cout << first_ name;
cout << "!\n";
as a single line of code?
Answer:
etc.
Question#5: What kind of literals are there?
Answer:
There are many types of literals.
1) Integer literals.
2) Floating-point literals.
3) Boolean literals.
4) Character literals.
5) String literals.
Question#6: What effect do tab, space and new lines have on program?
Answer:
Space is a escape sequence is use to give space between two words. “ends” is used to
give space.
Tab is also a escape sequence is used to give a horizontal tab in the program. We use \t
to give the tab.
e.g. cout<<”Zubaib ”<<ends<<”Shahid”;
New line is also a escape sequence is used to move on the next line. We use “endl” to move the
cursor to the next line.
e.g. cout<<”Zubaib”<<endl;
Question#7:What are the typical size of a char ,an int ,and a double?
Answer:
Char: 1 byte Int: 4 byte Double:
8 byte
Question#8: What measures do we use for the size of small entities in memory,
such as ints and strings?
Answer:
“BYTES” is the measures which we use for the size of small entities in memory.
Question#9: What is the difference between = and ==?
Answer:
= is the assignment operator which is used to assign the value to the variable.
e.g.
int z;
z=90;
on the other side
== is relational operator which is used to compare two value in the program.
e.g.
if(a==b)
Question#10: What is an initialization and how does it differ from an
assignment?
Answer:
Initialization mean at the time of deceleration we assign the value to the variable.
e.g.
int a=10;
whereas assignment operator is that in which when an initialized object is already
assigned a value from another existing object.
system("pause"); }
Output:
Question#13. Write a program that prompts the user to enter two integer
values. Store these values in int variables named val1 and val2. Write your
program to determine the smallest, largest, sum, difference, product, and ratio
of these values and report them to the user.
Answer:
#include
cin >> val2; if (val1 > val2) { cout << "The value " << val1 << " is largest"; cout << "The value " << val2 << " is smallest"; } else { cout << "The value " << val2 << " is largest"<<endl; cout << "The value " << val1 << " is smallest"<<endl; } sum = val1 + val2; cout <<"The sum of values is "<< sum << endl; difference = val1 - val2; cout <<"The difference of values is "<< difference << endl; product = val1*val2; cout <<"The product of values is "<< product << endl; ratio = val1 / val2; cout <<"The ratio of values is "<< ratio << endl; system("pause"); } Output:
Question#14:Modify the program above (Q13) to ask the user to enter floating-
point values and store them in double variables. Compare the outputs of the
two programs for some inputs of your choice. Are the results the same? Should
they be? What's the difference?
Answer:
#include
Question#15: Write a program to test an integer value to determine if it is odd
or even. As always, make sure your output is clear and complete. In other
words, don't just output “yes” or “no." Your output should stand alone, like
"The value 4 is an even number .".
Answer:
#include
Question#16: Write a program that generates the
following output:
Use an integer constant for the 10, an arithmetic
assignment operator to generate the 20, and a decrement
operator to generate the 19.
Answer:
#include
from user and draw the same table.
Answer(a):
#include
t11300\n1993\t16200\n"; system("pause"); }
Output:
Answer(b):
#include
