• char extraction operator (>>) how it behaves.
• flag control while loop do you use bool value? yes
• while loop ( ) <----- div="">
• how many times does a for loop execute/iterate. for(int i = 1; i<5 4="" div="" false="" i="" is="" so="" times.="" whenever="">
• know pre and post ++x(pre)/x++(post)
o ex.1
o x = 5;
o x++ = 5 //x = 6
o ++x= 7
o ex.2 a = 1;
o b = 0;
o b = ++a;
o a = 2;
o b = 2 ;
o -------------
o b = a++;
o b = 1;
• prototyping a function:
• #include
• using namespace std;
• void protoTypedFunction(int,int); the prototype
• know what an infinite loop is:
o ex: while(true)
• A while loop tell the output of it.
• Part of dev environment combines our pro./prog. from - assembler linker, decoder, complier.
• Know this something:
o cin >> x >> y;
o stdin: 5, 6; x = 5 y = 6
• interger division
• 19 / 7 = 2
• length of a string.
o string name = "Billy"
o length = 5
• cout << pow(pow(num, num), number) << endl;
o pow = power operator from cmath/math.h.
o pow(9,3) = 9^3 = 9 * 9 * 9
