I'm trying to find angles A,B,C using law of cosines and I want the answers to be in degrees and the formula to convert the answer to degrees is angle*PI/180. However the answer does not convert to degrees what am I doing wrong?
Code:
#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <cmath>
#define PI 3.14
using namespace std;
[Code].....
Are there STD functions for converting degrees to radians and radians to degrees?
I know I can write my own but in the particular application I would like to use built-in ones for maintainability.
I need to write a program to input 6 temperatures in degrees Fahrenheit and output it in degrees Celsius. I used a for loop but it keeps giving me 0 as the output whenever I enter a temperature...
Code:
#include <stdio.h>
#include <math.h>
int main() {
double farenheit,celsius;
for(int i=0; i<6; i++) {
printf("Enter temperature in degrees farenheit: ");
scanf("%lf",&farenheit);
celsius = (5/9)*(farenheit-32);
printf("Temperature in degrees celsius: %lf ",celsius);
} }
I am tying to convert an int to a char. Below is an example of the code that I have but I am getting an error('=':left operand must be l-value). I am not seeing a problem with the code.
int num = 5;
char temp[2];
char final[2];
itoa(num, temp, 10);
m_pRes->final = temp;

I developed this simple sample program to test cos():
Code:
#include <cmath>
#include <iostream>
using namespace std;
int main() {
const float radiansToDegrees = 180.0f / 3.141592653589793f;
float c = sqrt(2.0f);
float a = 1;
float angleRadians = cos(a/c);
float angle = radiansToDegrees*angleRadians;
}
I expected angle to be 45 exactly, but it's value is: angle = 43.558804
Why is the angle not 45 degrees? What did I do wrong?

Create a script that lets you rotate an image through some number of degrees(out of a maximum of 360 degrees). The script should let you specify that you want to spin the image continuously. It should let you adjust the spin speed dynamically.

I have a function that rotates a vector 90 degrees. Only problem is, i never get negative values. For some strange reason, no matter what i do, the value of x is positive. And even if the x is negative. Once i put it into direction (struct with 2 values x and y) it turns again to positive. Im using VSC++2013 ultimate. At first direction was SDL_Point, so i thought it was SDL problem, but now it seems its something else.
if (c == '-') {
int x = direction.y;
x *= -1;
int y = direction.x;
direction = { x, y };
}
Cannot manage to find the error source when i try running the program, the first part of the program runs just fine its when i try to get the temperature one that i get the error

Why is this
Code: fFile << (char) (i)p.x, (char) (i)p.y,(char) (i)p.z); not the same as this
Code: printf("%c%c%c", (i)p.x, (i)p.y, (i)p.z);
From my tests I found the problem to be somewhere in the Mantissa part that converts it to binary.
bool xsDLL GetHexFromSF_IEEE754( void* to, Text from, ui08 tSize ) {
from.UpperCase();
int db = 0, dB = 0, dBEnd = tSize, dBLast = ( tSize - 1u ), dbEnd = dBEnd * 8;
ui08 *data = reinterpret_cast< ui08* >( to );
for ( ; dB >= 0; --dB )
data[ dB ] = 0u;

Having trouble converting char to hex.
according to here [URL] ....
ô in decimal is 147 and print ô using alt 147
and here [URL] ....
ô in dec is 244 but prints ⌠ using alt 244
put on console
char c = ô;
cout << (int)c << endl;
prints -109 and print m using alt -109
I am using alt to test char output. Why I'm getting a negative value? Which of the tables are correct? I have string of char that I want to print in hex. I get a hex string but the hex value don't correspond to any of the two tables on the websites because the console converts special char to negative values.
I am having problems with converting a CString to an int and than doing checks on the int to see if it is in a particualr range.Below is what I am doing.
CString numstr = "28"
int num = atoi(numstr);
BOOL valid = TRUE;
if(num < -32,768 {
valid = FALSE;
}
For some reason when running the above code the if statement is executed but it should not be becasue 28 is not less than -32,768. Why this is happening, I am not seeing the reason for this at all!! The num variable is being assigned the correct value.
I am having trouble converting strings in my application.
This is the code that is eventually getting called, the first parameter takes a LPCWSTR
Code:

I have to convert my netpay which is a float to a string So if I input a value of say, 356.26 it should output "the sum of three hundred fifty-six and 26/100 dollars" . My program function works for the sum of three hundred but after that it spits out garbage.
i m trying to write a code that would convert a each letter from a text to their decimal images . while i was able to write the part of entering the text , i cant do the converting part , i searched all day on the internet and found nothing.
View 3 Replies View RelatedWrite a program to convert the time from 24-hour notation and vice versa. Your program must be menu driven, giving the user the choice of converting the time between the two notations. Furthermore your program must contain at least the following function : a function to convert the time from 24-hour notation to 12-h notation, a function to convert the time from 12-hour notation to 24-hour notation, a function to display the choices, function(s) to get the input, and function(s) to display the results.

Sandy is of class Person, who converts to Muslim and takes on a new name Fatima, and has all the attributes of Sandy, with new Muslim attributes (e.g. religion == Islam, etc..). At this point, Sandy can be deleted, and Fatima, now of class Muslim will play Sandy's role henceforth. The problem is that due to her new address, all the people who knew Sandy does not know Fatima. Manually changing Sandy's address to Fatima's address for all those people who knew Sandy is clearly not an acceptable method. I looked through all the design patterns and cannot find one to solve this problem. how to improve the design? Here's my simplified code showing the problem:
#include <iostream>
#include <string>
#include <typeinfo>
class Person {
std::string name;
Person* bestFriend;
[Code]...
Output:
sandy = 0x32658, 6Person
Mary's best friend is Sandy.
fatima = 0x23fec0, 6Muslim
Mary's best friend is Sandy.
Of course, we want to have: Mary's best friend is Fatima,. with mary->getBestFriend()->getReligion() == Islam, etc... How to redesign the whole thing so that this is automated (assume there are thousands of people who know her)?
