    1. % : this modular division operator in c programming

      Delete
    2. So,SACHIN,if n%10 equals 0,this means n is exactly divisable by 10.Or whatever you need.So this is also the reason why n%2 would tell you if n is odd or even.Because n%2 can only give you 0 if n is exactly divisable by 2,therefore been even,or 1 if n is not exactly divisable by 2,therefore been odd.

  90. please can someone write this program for me......its a project whc z givn me difficulty....
    write a program for a car sale.You have to provide 4 basic functionalities.These are ;
    1-add (adding a new car)
    2-List (Listing existing cars )
    3-Update (Update a car info)
    4-Search (Search for a car)
    DETAILS: Maximum capasity that can be stored at garage is 500. A car has following properties
    Example :
    1. license plate
    2. Fabrication year
    3. Make
    4. Model
    5. Price
    6. color
    1. 34ABC51
    2. 2000
    3. Audi
    4. A3
    5. 10 000$
    6. red
    Males:Audi,Bmw,Ford,Kia,Nissan,Opel,Toyota
    Check for related models from internet and include them on your project , 4 models
    are enugh for each Male.
    Colors:Red,Green,Blue,Orange,Yellow,Pink,Violet,Magenta,White,Black
    Functionalities:
    Provide a menu for user that can choose an operation (add,list,search,update,exit)
    1-Adding a new car :
    When user select add , display a list of existing males automaticly(Ex:
    1:audi,2:Bmw...) , suppose user entered 1(Audi).Then list existing models (Ex.
    1:A3,2:A4...) , after user chosed model ,display color list and then read other
    paramaters from user.
    2-Listing car list:
    Listing output should look like ;
    AUDI’ES
    Model Count
    A3 5
    A4 7
    A6 8
    Total : 20
    And same for other Males.
    3-Searching car int the list:
    You will implment searching operation related to the price.Read min and max values
    from list and display all cars from this list which prices are between min and max values.
    A sample output could look like :
    Suppose user entered 5000 for min and 25000 for max ,
    Number of cars found 2

  136. Write a program to 'search' for a 'real number' in a sentence, convert it to a floating point number.
    • The program must read in all of the user input (i.e. the sentence) in one character array of appropriate size. It then searches to find a real number and then convert it to a 'float' data type.
    • The size of the sentence is not fixed but will not exceed 999 characters.
    • The sentence will not have any decimal point or dot '.' other than within the number.
    • The sentence will not have any hyphen or minus sign '-' other than at the start of the number.
    • The number will not contain any space or comma.
    • There is no limit to number of decimal places in the number but they will fit within the range of float.
    • There will only be one number in the whole sentence.
    • The user types in the sentence and presses 'Enter' at the end to mark the end of input.

    For example some legal input sentence are:
    The minimum distance of moon from earth is 362570 km
    The best current estimate of the age of the universe is 13.75 billion years
    The Amoeba proteus may reach 800 micro meter in length
    The lowest temperature ever recorded on the surface of Earth is -89.2 degrees centigrade
