PROGRAMMING –ASSIGNMENT 1

1. Define a class student with the following specification:Private members of class student

Admno interger sname 20 characterEng,math,science float Total float Ctotal() a function to calculate

eng+math+science with float return type

Student Public member function of class

Takedata() - Function to accept values for admno, sname, eng, math, science andinvoke ctotal() to calculate total.

Showdata() - Function to display all the data members on the screen.

#include<iostream.h>#include<conio.h>class student{ private: int admno; char sname[20]; float eng,math,sci; float total; void ctotal(){ total=eng+math+sci; }

public: void takedat(){ cout<<"\n Enter admission no,student name"<<"\n"; cin>>admno>>sname; cout<<"Enter marks of english,maths,science"<<"\n"; cin>>eng>>math>>sci; ctotal(); ] void showdata(){ cout<<”……..Student details……..”<<”\n”; cout<<"Admission number="<<admno<<"\n"; cout<<"Student name:"<<sname<<"\n"; cout<<"English marks:"<<eng<<"\n"; cout<<"Maths marks:"<<math<<"\n"; cout<<"Science marks:"<<sci<<"\n"; cout<<"Total marks:"<<total; } };

PROGRAMMING ASSIGNMENT -2

1. Admission to a professional course is subject to the following conditions:a] Marks in mathematics >=60

b] Marks in physics >=50

c] Marks in chemistry >=40

d] Total in all three subjects >=200

or

Total in mathematics and physics >=150

Given the marks in the three subjects, write a program to process the applications to the eligible candidates.

import java.io.BufferedReader;

import java.io.*;

public class Admission {

public static void main(String args[])throws Exception{

BufferedReader br=new BufferedReader(newInputStreamReader(System.in));

int math,phy,chem,total;

System.out.println("Enter the marks for maths sub:");

math=Integer.parseInt(br.readLine());

System.out.println("Enetr the marks for phy sub:");

phy=Integer.parseInt(br.readLine());

System.out.println("Enter the marks for che sub:");

chem=Integer.parseInt(br.readLine());

total=math+phy+chem;

if((math>=60)&&(phy>=50)&&(chem>=40))

System.out.println(" congrats!!!!....candidate is elgible for the admission ");

else if(total>=200)

System.out.println(" congrats!!!!....candidate is elgible for the admission ");

else

{

if((math+phy)>=150)

System.out.println(" congrats!!!!....candidate is elgible for thadmission ");

else

System.out.println("sorry !!!!!candidate is not elgible for admission");

}

}

}

Sample output:

1.Enter the marks for maths sub:50

Enetr the marks for phy sub:60

Enter the marks for che sub:70

sorry !!!!!candidate is not elgible for admission

2. Enter the marks for maths sub:70

2. A cloth showroom has announced the followingseasonal discounts on purchaseof items:Discount Mill Cloth Handloom items

0 - 100 -- 5.0 %

101 - 200 5.0 % 7.5 %

201 - 300 7.5 % 10.0 %

Above 300 10.0 % 15.0 %

Write a program using switch and if statements to compute the net amount to be

paid by a customer.

import java.io.BufferedReader;

import java.io.*;

import java.util.*;

public class Discount {

public static void main(String args[]) throws Exception{

BufferedReader br=new BufferedReader(newInputStreamReader(System.in));

Scanner scan=new Scanner(System.in);

int ch,total,am;

String answer="";

do{

System.out.println("pls enter your amount");

am=Integer.parseInt(br.readLine());

System.out.println("pls select your type of cloth:");

System.out.println("1.Mill cloth");

System.out.println("2.Handloom item");

ch=Integer.parseInt(br.readLine());

switch(ch)

{

case 1:

if(am<=301)

{

if(am<101)

{

System.out.println(" Total amount you have to pay :");

total=am;

System.out.println(+total);

}

else

{

if(am<201)

{


total=(am)-((am*5)/(100));


}

else

{


total=(am)-((am*7)/(100));


}

}

}

else {


total=(am)-((am*10)/(100));

System.out.println(+total);}

break;

case 2:

if(am<=301){

if(am<101){


total=(am)-((am*5)/(100));


else{

if(am<=201){


total=(am)-((am*7)/(100));


else {


total=(am)-((am*10)/(100));

System.out.println(+total);}}}

else {


total=(am)-((am*15)/(100));


break;

}

System.out.println("if u want to continue then press Y or else N:");

answer=scan.next();

}while(answer.equals("y"));

}

}

SAMPLE OUTPUT:

1. pls enter your amount:178

pls select your type of cloth:1.Mill cloth

2.Handloom item

1

Total amount you have to pay :170

if u want to continue then press Y or else N:

y

pls enter your amount:90


2.Handloom item

1


if u want to continue then press Y or else N:

y

pls enter your amount:370


2.Handloom item

2


if u want to continue then press Y or else N:n

3. Write a program to find the number of and sum of all integers greater than 100

and less than 200 that are divisible by 7.

Import java.io.*;

public class HelloWorld{

public static void main(String[] args) {

int sum=0;

int count=0;

for(int i=100;i<=200;i++)

{

if(i%7==0){

System.out.print("The number which is diisible by 7 :");

System.out.println(i);

sum=sum+i;

count++;}

}

System.out.print("The sum of numbers :"+sum);

System.out.println("The total num of integers:"+count);

}

}

SAMPLE OUTPUT:

The number which is diisible by 7 :105














The sum of numbers :2107

The total num of integers:14
