C/C++ :: Fraction Calculator - Converting From Fraction To String
May 27, 2014I'm having a problem when i convert from fraction to string. When I run my program it runs fine I'm supposed to get an output of the fraction ex (2/5) and the decimal 0.4 the problem is that it does not output the fraction all I get it / and 0.4
the code for converting from fraction to string is the following
std::string string;
char numerator[100]/* = {0}*/;
char denominator[100]/* = {0}*/;
_itoa_s(numerator_, numerator, 10);
_itoa_s(denominator_, denominator, 10);

C :: Binary Number To Decimal
Mar 30, 2014I am very new to programming and have been working on a program that can receive decimals or binary numbers and convert them. The decimal --> binary works fine. For some reason I cannot figure out I cannot get the "BinaryToDecimal" function to perform. By putting a "printf" into the for-loop.
Code:
#include <stdio.h>#include <string.h>
#include <math.h>
char* ReverseString (char _result[]) {
int start, end, length = strlen(_result);
char swap;

C/C++ :: Binary Number Into Decimal?
Sep 10, 2014I have a code and am asked to modify it so that it will take as input as unsigned binary number up to 16 digits in length and convert it into its equivalent decimal number and output that decimal number.
All I know is that I use library function strlen() in <cstring> to calculate the length of the input string.
I also know I have to use something called pow(2,4);
//pow (); is found in cmath
I was told to use sum = sum >>16-l; (l is the length of />/>

Maybe, convert to string than remove the first character from the string than convert the string back to an int?

C++ :: Enter Decimal Number Into Program And Required Base
Oct 12, 2013You enter decimal number into the program and what base you want. The integer part of the decimal is being handled fine, but the decimal is not.
For example, I enter 15.6847 and base 10, which means I'm going from base 10 to base 10. It spits out 68469999999999 for the decimal part. (Do not worry about the first block of numbers. The second block seperated from the first by a space is where the decimal will appear in order.)

C/C++ :: How To Convert Byte Array With Hex Number To Equivalent Decimal Value
Sep 18, 2012I tried to convert byte array with hex to equivalent decimal value as follows but it gives me unexpected results:
byte hex_arr[] = { 0x00, 0x01, 0xab, 0x90};
unsigned long i=0;
i = hex_arr[3] + (hex_arr[2] << 8) + (hex_arr[1] << 16) + (hex_arr[0] << 24);
the output is 4294945680
Correct output should be 109456
but when I try with byte hex_arr[]={0x00,0x00,0x0f,0xff};
it gives correct out put 4095
the correct output works until the hex values is {0x00,0x00,0x7f,0xff}
Visual C++ :: Converting Decimal Number Given By User To Binary?
Dec 19, 2014Write a C++ program that adds three binary numbers of 8-bit each. Every number is stored into an array of 8 elements.
Example:
Array A
0 1 2 3 4 5 6 7
0 1 1 0 1 1 1 0
+
Array B
0 1 2 3 4 5 6 7
0 1 1 0 1 1 1 0
+
Array C
0 1 2 3 4 5 6 7
0 1 1 0 1 1 1 0
Store the result into an array D of 8 elements. Your program should show the decimal numbers for every binary number. Print screen of 6 answers. This means you should try your program six times with different numbers in every run and show the printed screen result.
