By c++ programming i want to do this simple excercise

1) Convert the below nested if statement to a switch statement:

1. cin>>number ;

if( number == 3 )

cout<< Three ;

else if (number == 4 )

cout<< Four ;

else if (number == 7 )

cout<< Seven ;

else if (number == 9 )

cout<< Nine ;

else

cout<< Zero ;

2. if(x ==1)

code = 77;

else if(x==3)

code = 14 ;

else if(x == 5)

code = 32 ;

cout<< code;

3. if((c=='a')||(c=='u')||(c=='i')||(c=='e')||(c=='o'))

vowel++ ;

else if((c=='h')||(c=='k'))

exception++ ;

else if( c=='z')

zero++

else

others++ ;

4. if ((ch == E) || (ch == e))

cout<< Display Edit Menu. ;

else if ((ch == A) || (ch == a))

cout<< Display Append Menu. ;

else if ((ch == S) || (ch == s))

cout<< Display Search Menu. ;

else if ((ch == R) || (ch == r))

cout<< Display Report Menu. ;

else if (( ch == q) || (ch == Q))

exit (0) ;

else

cout<

6] Convert the following switch statement to nested if () statements:

1. Switch(color)

{ case 3 : code = 1300 ; Break;

case 5 : code = 4200 ; Break;

case 6 : code = 7700 ; Break;

default : code = 300 ; }

2. d = day % 7 ;

switch (d)

{ case 1 : cout << "Saturday"; break;

case 2 : cout << "Sunday"; break;

case 3 : cout << "Monday"; break;

case 4 : cout << "Tuesday"; break;

case 5 : cout << "Wednesday"; break;

case 6 : cout << "Thursday"; break;

case 0 : cout << "Friday"; break;

default : cout << "Not an allowable day number"; }

3. cin>>day ;

switch (day)

{ case 7 :

case 1 : cout << "This is a weekend day"; break;

case 2 :

case 3 :

case 4 :

case 5 :

case 6 : cout << "This is a weekday"; break; default : cout << "Not a legal day"; }

4. switch(status)

{ case 's' : case 'S' : cout<<"Single"; break;

case 'm' : case 'M': cout<<"Married"; break;

case 'd' : case 'D' : cout<<"Divorce"; break;

case 'w' : case 'W': cout<<"Widow"; break;

}
