homework again ! :D

1) Complete the code that can calculate total marks for 3 students
for(int stud=1;____(a)____;stud++)
{
cout<<"Enter Student name:";
____(b)____name;
for(int mark=1;mark<=3;____(c)____)
{
cout<<"Enter assigment marks:";
cin>>marks;
total=____(d)____+marks;
}
}
cout<<"Total marks are"<<____(e)____;

(a) stud<=3
(b) cin>>
(c) mark++
(d) total
(e) total

2) Based on the short code below :
Change for loop statement below to while loop
for(x=1;x<=5;x++)
cout<<x<<"\t"<<x*2<<"In";

x=1;
while(x<=5)
cout<<x<<"\t"<<x*2<<"In";
x++

3) Write the code using while loop to get the output as below !
    20
    15
    10
    5
 
x=20
while(x<=5)
cout<<" "<<x;
x--;

yg niy aq tataw betol ke tak . sbb nyeer mis blom check . so klu aq ade sala, tlg sesaper tego aq k ? tnx :))

last exercise b4 our examination

1) Change the if...else statement below to switch...case statement
#include<iostream.h>
main()
{
int nomA,nomB,selection,value;
cout<<"Enter 2 number:";
cin>>nomA>>nomB;
cout<<"1.Addition";
cout<<"2.Substraction";
cout<<"3.Multiply";
cout<<"4.Division";
cout<<"Enter selection=";
cin>>selection;
if(selection==1)
{value=nomA+nomB;}
else if(selection==2)
{value=nomA-nomB;}
else if(selection==3)
{value=nomA*nomB;}
else if(selection==4)
{value=nomA/nomB;}
else
{cout<<"Invalid selection";}
cout<<"The value is:"<<value;
return 0;
}

#include<iostream.h>
main()
{
int nomA,nomB,selection,value;
cout<<"Enter 2 number:";
cin>>nomA>>nomB;
cout<<"1.Addition";
cout<<"2.Substraction";
cout<<"3.Multiply";
cout<<"4.Division";
cout<<"Enter selection=";
cin>>selection;
switch(selection)
{
case1:"value=nomA+nomB";break;
case2:"value=nomA-nomB";break;
case3:"value=nomA*nomB";break;
case4:"value=nomA/nomB";break;
default:cout<<"Invalid selection";
cout<<"The value is:"<<value;
}
return 0;
}

2) Change the for loop statement below to while loop
#include<iostream.h>
main()
{
int i,power2;
for(i=1;i<=9;i++)
{
power2=i*i;
cout<<" "<<i<<"power2"<<power2;
}
return 0;
}

#include<iostream.h>
main()
{
int i,power2;
//while
i=1;
while(i<=9)
{
power2=i*i;
cout<<" "<<i<<"power2"<<power2;
i++;
}
return 0;
}

3) Write a program that input 2 numbers. Compare the numbers & display only the biggest number. If the numbers are same, display the numbers are same.
#include<iostream.h>
main()
{
int nomA,nomB;
cout<<"Enter 2 numbers=";
cin>>nomA>>nomB;
if(nomA>nomB)
{cout<<"nom A is bigger than nom B";}
else if(nomA==nomB)
{cout<<"nom A is same as nom B";}
else
{cout<<"Invalid";}
return 0;
}

4) Write a program using for loop that receive prices of 3 products. Calculate the price that must be paid after 10% discount is given to every customer.
#include<iostream.h>
main()
{
int x,price,total,discount;
for(x=1;x<4;x++)
{
cout<<"price["<<x<<"]:";
cin>>price;
total=total+price;
}
cout<<"total="<<total;
discount=total*0.10;
cout<<"discount"<<discount;
return 0;
}

5) What is the output for the following program segmment
i) int x=20;
   for(int i=5;i<=x;i++)
  {
   cout<<i;
   i=i+4;
  }

  5
  10
  15
  20

ii) int mul=1;
   do
  {
   mul=mul*2;
   cout<<"The mul is:"<<mul;
   mul++;
  }
  while(mul<10)

Exercise niy ktorang wt tyme mis wt extra class b4 exam . mis suh student wt kt white board . aq kne wt num 2 . pas uh aq sala sbb lupe na ltx semikolon . hmm cuai aq niy )= sume soalan niy mis da check n discuss nan ktorang . so jwpn dy insyallah betol (:

for loop & while loop pulaaak !

FOR LOOP
#include<iostream.h>
main()
{
//declare variable
int x,y;
cout<<"Enter an integer=";
cin>>x;
//loop for
for(y=1;y<x;y++)
{
cout<<" "<<x;
}
return 0;
}

WHILE LOOP
#include<iostream.h>
main()
{
//declare variable
int x,y;
cout<<"Enter an integer=";
cin>>x;
//while
y=x;
while(y<x)
{
cout<<" "<<x;
y++;
}
return 0;
}

QUESTION 2
Change the if...else statement below to switch...case statement
#include<iostream.h>
main()
{
int selection,quantity;
float price;
cout<<"1.pen=rm0.50";
cout<<"2.pencil=rm0.30;
cout<<"3.ruler=rm0.20";
cout<<"4.Erasor=rm0.10";
cin>>selection;
cin>>quantity;
if(selection==1)
{price=quantity*0.50;}
else if(selection==2)
{price=quantity*0.30;}
else if(selection==3)
{price=quantity*0.20;}
else if(selection==4)
{price=quantity*0.10;}
else
{cout<<"Invalid selection";}
cout<<"the price is :"<<price;
return 0;
}

#include<iostream.h>
main()
{
int selection,quantity;
float price;
cout<<"1.pen=rm0.50";
cout<<"2.pencil=rm0.30;
cout<<"3.ruler=rm0.20";
cout<<"4.Erasor=rm0.10";

switch(quantity,selection)
{
case 1:"price=quantity*0.50";break;
case 2:"price=quantity*0.30";break;
case 3:"price=quantity*0.20";break;
case 4:"price=quantity*0.10";break;
default:cout<<"Invalid selection";
cout<<"The price is :"<<price;
return 0;
}

jom blaja pasal if...else statement & switch...case statement

ok bdasarkan table kt ats . kite bole wt program dlm 2 jenis bentuk . sama ade dlm bntuk if...else ataupon switch...case . ok now kite wt dlm bentuk if..else statement dlu k ..

IF...ELSE STATEMENT

#include<iostream.h>

main()

{

//declare variable

int age;

//input

cout<<"Enter your age=";

cin>>age;

//if...else statement

if(age>=1||age<=6)

{cout<<"you are kids !!";}

else if(age>=7||age<=12)

{cout<<"you are child !!";}

else if(age>=13||age<=21)

{cout<<"you are teenager !!";}

else if(age>=22||age<=30)

{cout<<"you are adult !!";}

else if(age>30)

{cout<<"you are old !!";}

else

{cout<<"Invalid selection";}

return 0;

}

SWITCH...CASE STATEMENT

#include<iostream.h>

main()

{

//declare variable

int age;

//input

cout<<"Enter your age=";

cin>>age;

//switch...case statement

switch(age)

{

case('age'>=1||'age'<=6):cout<<"you are kids !!";break;

case('age'>=7||'age'<=12):cout<<"you are kids !!";break;

case('age'>=13||'age'<=21):cout<<"you are kids !!";break;

case('age'>=22||'age'<=30):cout<<"you are kids !!";break;

case('age'>30):cout<<"you are kids !!";break;

default:cout<<"Invalid selection";

}

return 0;

}

hmm kadang soklan suh kite tuka if...else jd switch...case . kadang tuka switch...case g if...else . tp kadang soklan ta bg programming, tp kite kene develop sndry..





mid term da lepas .. alhamdulillah :D

hmm td tepat pkul 1p.m xm FOP . jantong aq mcm na gugo .tkot yg teramat sgt . sbb subject niy kan susa . tp alhamdulillah aq dpt jwb . cume yg variable name tuh aq btol btol lupe . terpakse tembak ;P hehe hm lw stakat na lulus bole la, tp lw na dpt highest mimpi jelaaa ): hmm btw, td mis ade tulis kt white board suh siap kn blog, sume ass n sume weekly reflection . tekejot aq bc . hmm due date ary niyy lak tuhh . adehh hope mis check blog aq nt tga tga mlm . lw skg, mmg ta lengkap ag la . jp g na wt k (:
