Question
a. If you wanted to explicitly include a double-quotation-mark in your string what would you have to type? For example how would you output: I said "hello" fool! b. what is the value of 12%5? c. If y = -4, what value is x assigned by the statement int x = (y > 0) ? -1: 1: d. Given a string hello = "Test", what would be the value of hello [5] ? e. How about hello[1]? C ++ Math Write complete C++ statements for each of the following mathematical expressions you may assume proper libraries have been #include-ed and all variables have been declared as type double. Y = squareroot 10^x + x^r-3 r= t sin (4a)+ 2/3Explanation / Answer
//First part
a) double quotation mark
//in java
String print = "I said "hello" fool";
//in c++
String print ="blah blah "trying to" blah blah";
cout>>print;
b) modulo prints the reminder.
hence 12%5 is 2
c) if y=-4
int x=(y>0) ? -1 : 1;
answer: codition returns true false.
that means if (y>0) is true then value before : will be printed else value after : will be printed.
(-4>0) its true hence output will be -1
d) string hello="test"
indexing starts with 0. we have a 4 characters starting from 0.
0-t
1-e
2-s
3-t
hello(5) will print 'null';
e) hello(1) will print 'e';
//second part
a) use "pow" and "sqrt" built in function.
input:- base, exponsion.
pow(base, exponsion);
example: double base=20.0, exponsion=4.0;
double result=pow(base,exponsion);
and squart root
sqrt(value);
sample example double result=sqrt(25)
example double result=sqrt(pow(10,x)+pow(x,r-3))---please provide x y and r values.
b) double sin (double x);
float sin (float x);
long double sin (long double x);
example sin(value)*1/2;
