Comp 1500 Test 2

int

integer

float

floating point number (less precision)

double

floating point number (greater precision)

bool

Boolean [true or false]

char

character [stored by ASCII value]

two way choice

if (cond)
A;
else
B;

*if either of these is longer than one line, that one needs a { }

pre test loop

while (cond)
A;

post test loop

do
A;
while (cond);

The four parts of any valid loop:

1. Initialization
2. Continuation
3. Update
4. Loop Body

example of fixed

float f = 1.5;
cout << fixed << f;

output: 1.500000

scientific ex

float f = 1.5;
cout << scientific << f;

output: 1.500000e+00

defaultfloat

float f = 1.5;
cout << f << endl; 1.5
cout << fixed << f << endl; 1.500000
cout << defaultfloat << f; 1.5

setprecision

float f = 1.5;
cout << fixed << f << endl; 1.500000
cout << setprecision(2) << f; 1.50

setw

string s = "Hello!";
cout << s << endl; Hello!
cout << setw(10) << s; [4 spaces] Hello!

setfill

string s = "Hello!";
cout << setw(10) << setfill('$') << s; $$Hello!

left, right

string s = "Hello!";
cout << setw(9) << s << endl;
cout << setw(9) << left << s << endl;
cout << setw(9) << right << s << endl;

Hello!
Hello!
Hello!
