http://www.daniweb.com/software-development/c/threads/15045/draw-sin-curve-w-user-input-how-to-code-sin

in this link what is m_iSample, double iSinValue, int iFinalSinValue, and other stuffs????

Answer 1

Dear it is a programming language so when ever we use a variable of type double , int , float or etc we got to name it.
and iSinValuer , count etc are name of those variables nothing more then this :) i hope u understand

Answer 2

i know that they are declarations but I do not know how they are used in the link ABOVE

Answer 3

for (count = 0; count<=m_iSample; ++count) {
double iSinValue=sin(count * PI);//do the sin calculation
int iFinalSinValue=iSinValue * 200;//convert result so that it will display correctly
pDC->LineTo( ??? , iFinalSinValue);//draw the line
}

this is the code as u know for loop is m_iSample are user chosen lines
iSinValue is a double variable that stores value of count*Pi that is
o,1,2,3,4, upto lines chosen by the user.
then iFinalSinValue is used to multply iSinValue with 200 // for conversion
and last line is to draw it

Answer 4

can you help me draw a sin curve in C ????

Answer 5

actually m from JAVA brother i can only let u understand the code of C but i cant program it i can just give u a simple pseudocode :)

Answer 6

i can also understand java so dont worry xD
