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++;

}

}

{

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;

}

}

total + price;

}

cout<<"total = " << total;

discount = total * 0.01;

cout<<"discount = "<

return 0;

}

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)

EXERCISE C1 & C2

Add and minus two INTEGER numbers with using the formula below:


add= num1+num2
minus= num2-num1

ANSWER

# include <> #header
main ( )
{
// variable declaration
int num 1,num 2,add,minus ;
// input 1
Cout << " enter num 1 : " ;
Cin >> num 1 ;
// input 2
Cout << " enter num 2 : " ;
Cin >> num 2 ;
// formula
add = num 1 + num 2 ;
// output
Cout << add =" <<">
// formula
minus = num 2 - num 1 ;
// output
Cout << " minus = <<
minus ;
return 0 ;
}

#include //header

Main( ) //start body

{ // Open curly braket

//declare variable

Float area;

Float radius;
