QUESTION 1
change the if....else statements below to switch.....case statements:
#include
main()
{
int nom A,nom B,Selection,Value;
cout<<"enter 2 numbers:";
cin>>nomA >>nomB;
cout<<"1.addition";
cout<"2.subtraction";
cout<<"3.multiply";
cout<<"4.division";
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";}
<<"the value is:"<

ANSWER:

#include

main()

{

int nom A,nom B,Selection,Value;

cout<<"enter 2 numbers:";

cin>>nomA >>nomB;

cout<<"1.addition";

cout<"2.subtraction";

cout<<"3.multiply";

cout<<"4.division";

cin>>selection;

switch (selection)

{case 1:value=nomA + nomB;break

case 2:value=nomA - nomB;break

case 3:value=nomA * nomB;break

case 4:value=nomA / nomB;break

default cout<<"invalid selection";

cout <<"the value is"<

}

return 0;

}

QUESTION 2

change for loop statement below to while loop.

#include

main()

{

int i,power 2;

for (i=1;i<=9;i++)

{

power 2= i * i;

cout<<" "<

}

}

ANSWER

#include

main()

{

int i,power 2;

while

i = 1;

while ( i <=9 )

{

power 2 = i * i;

cout <<" "<< i << "power 2" << power 2;

i++;

}

}

QUESTION 3

write a program that input 2 numbers.compare and display only the biggest number.if the numbers are same,display the numbers are same

ANSWER

#include

main()

{

int num1,num2;

cout<<"enter 2 numbers:";

cin >> nomA >> nomB;

//if...else statement

if (num 2 > num 1)

{ cout <<"num 2 is bigger than num 1";}

else if (num 2 == num 1)

{ cout <<"num 2 is same as num 1";}

else

{ cout <<"invalid selection";}

return 0;

}

QUESTION 4

write a programming using for loop that recive pricess of 3 products.calculate the price that must be paid after 10% discount is given to every customer.

ANSWER

#include

main()

{

cin>>price;

}

total + price;

}

cout<<"total = " << total;

discount = total * 0.01;

cout<<"discount = "<

return 0;

}

QUESTION 5

LOOP AND WHILE

LOOP
#include
main()
{
//declare variable
//get input
cout <<"enter an integer = ";
cin >> x;
//loop for
for (y=0;yWHILE
#include
main()
int x.y;
cout<<"enter an integer =";
cin>>x;
//while
y=1;
while (y

IF ELSE TO SWITCH CASE

if,,,else or switch case,,,depends on question

If else statement

#include

main ()

{

declare variable

int age;

//input

cout<<"enter your age =";

cin>>age;

//if..else statements

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

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

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

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

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

else if (age >30)

{ cout <<"you are old booooo.....";}

else

{cout<<"invalid selection";}

return o;

}

SWITCH CASE

#include

main ()

{

declare variable

int age;

//input

cout<<"enter your age =";

cin>>age;

switch..case statements

switch (age)

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

case ('age'>=13 ll 'age' <= 12):cout<<"you are adult!";break;

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

case ('age'>= 22: ll 'age' <=30):cout<<"you are adult now!!";break;

case ('age'>=30):cout<<"you are old booooo.....";break;

default: cout<<"invalid selection";

}

return 0;
