C/C++ :: Program To Print Out Binary Value Of 16 Bit Number

Sep 22, 2013

Write a program to print out the binary value of a 16 bit number.

Create integers i, count, and mask.

Set 'i' to a hex value of 0x1b53.

Set mask to a value of 0x8000. Why?

print a line to show the hex value of i and then the leader for the binary value like this: Hex value = 1b53 Binary=

Use a for loop to loop 16 times and print 16 digits, using count as the loop counter

To test for each digit value, bitwise and 'i' with 'mask'

when the result for the bitwise and is true, print the number '1'

when the result for the bitwise and is false, print the number '0'

then shift mask one place to the right

print a new line and then quit

Use prtscrn and make a hard copy of the code with the console output.

Extra: use the modulus of count and print a space after every 4th digit to make the binary easier to read

The output should look like this: Hex value = 1b53, Binary= 0001 1011 0101 0011

so far this is what i have

#include <stdio.h>
#include <stdlib.h>  
int main() {
    int i, count, mask;
    //   1B53  0001 1011 0101 0011
    //   8000  1000 0000 0000 0000
    i = 0x1b53;

[Code] ....

it is telling me that there is an "else" without previous "if", also is the program that I wrote correct?

C++ :: Print Out Number Of Twin Primes Program

Jul 27, 2014

This program prints out the total number of up to 100,000. How to do is to print out the number of twin primes up to 100,000. Is it as simple as adding an if statement "if(primesList[j] - i == 2)"?

#include <iostream>
#include <string>
#include <cmath>
using namespace std;
int main() {
int primesCount = 0;

C/C++ :: Number To Binary Converter Program?

Sep 21, 2014

I recently wrote a program to convert numbers to binary in c++, Well here it is:

#include <iostream>
void recur(int convert) {
if(convert == 0) //if input is 0 , return nothing. {
return;
}
recur(convert/2); // divide convert by 2, get only a 1 or 0

C/C++ :: Program To Scan Number And String Then Print Them To A File

Mar 19, 2015

I wrote this program to scan a number and a string until EOF then print them to a file named "data.list". the problem is that the program duplicates last line of input in the output file. so for example if the input is :

1 test
2 dream
3 code

then output (in data.list file) would be:

1 test
2 dream
3 code
3 code

I also changed the program code so that it reads from data.list file. even here it duplicates last line!

so when program reads the info above saved in data.list it would be:

1 test
2 dream
3 code
3 code
3 code

here's the code for writing:

#include <stdio.h>
int main( void )
{
int num;
char str[80];
FILE *fPTR;
fPTR = fopen( "data.list", "w" ); // opens a file named "data.list", create if doesn't exist
while(!feof(stdin)) // loop until End-Of-File is pressed. Ctrl-Z in Windows, Ctrl-D in Unix, Linux, Mac OS X

[Code]...

and the one for reading from file:

#include <stdio.h>
#include <conio.h>
int main( void )
{
int num;
char str[80];
FILE *fPTR;

[Code]...

How do I fix this behavior??

C/C++ :: Program That Complete Binary Number Using Recursion

So Im trying to make a program that completes a binary number and I have to use Recursion. Heres an example:

0110

2] ./binary_string.out xx

#include <string.h>
char* convertString(char *c,int len);
int main(int argc,char *argv[]) {
int i,length;

C/C++ :: Program That Read A Number From Keyboard And Print Separated Digits To Screen

Feb 18, 2015

Basically this is what i need to do. Write a program that reads a number from the keyboard, separates it into its individual digits and prints the digits to screen, each on its own line followed by the same number of stars as itself.

For example, if the number is 2339 the program should print

9 *********
3 ***
3 ***
2 **

So far i have managed to separate the number and have them on different lines, but how to implement the stars onto each line with the number!

My code so far:

int main() {
int n;
printf("number? ");
scanf("%d", &n);
while (n > 0) {
printf("
%d

C++ :: Print All 64-bit Binary Numbers

Jul 31, 2013

I have a program in c++ to print all the binary numbers that have 64 bits. But the problem is it works only for 30 bits. Beyond that the program does not work possibly because of insufficient space availability.

my code is as below:

// C++ program to generate n-bit binary numbers
#include <iostream>
#include <string>
#include <vector>
#include <fstream>
using namespace std;

// This function generates all n bit Gray codes and prints the generated codes
void generateSequence(int n)

C++ :: Print Hexadecimal Strings From Binary

Aug 19, 2013

How to search in C or C++ a hexadecimal patterns within a binary file.

For example:

String1:

Code: 0x44 0x65 0x07

Then, once found, extract those 3 bytes and the next 11 bytes (14 bytes in total).

Finally, from those 14 bytes, print without spaces "bytes 1 to 6", "bytes 6 to 12", and byte "13 to 14".

Then I would like to print last 2 bytes (13 to 14) joined in decimal format.

The output without any conversion would be:

Code:
446507c90688 888000800005 0015
4465072ec918 059173495269 002C
44650700cc01 01811bc90b00 00AB

But the output converting to decimal the last 2 bytes would be:

Code:
446507c90688 888000800005 21
4465072ec918 059173495269 44
44650700cc01 01811bc90b00 171

The sample file is attached, and looks like this:

Code:

06 00 00 80 00 00 00 80 09 3c c9 06 88 88 80 00
80 00 44 65 07 c9 06 88 88 80 00 80 00 05 00 15
37 06 01 00 00 01 00 65 00 00 00 02 00 00 02 00
18 00 00 00 03 00 00 03 00 17 00 00 00 04 00 00

C++ :: Convert List Of Binary Numbers From A File Into Decimal And Print To Screen

Sep 23, 2014

I am trying to make a program that will convert a list of binary numbers from a file into decimal and print the decimal to the screen. I have no problem doing the conversion, the problem comes up when our teacher wants the input file in a format as such:

3
10110101
11111111
10101010

The first number is supposed to tell the program how many different 8bit strings it is going to have to convert, and then the following lines are those binary numbers.

I am not very experienced with file inputs, and I know how to open files and read lines in.. The problem is, how to say "ok the first line says 3, so now I have to convert the next 3 lines" . I am assuming it is just a simple loop that I am missing....

C++ :: Count Number Of 0 In Binary Number

Apr 11, 2013

i am writing a program that accepts a decimal number from the user and convert it to binary numbers. After the conversion, i should count the number of 1's and 0's in the said binary number. I got upto converting and counting 1's using Brian Kernighan’s Algorithm. But, i can't seem to get it to count the number of 0's.

#include <iostream>
#include<bitset>
using namespace std;
int main() {
int num,count=0,Zero,count1 =0;
cout<<"Enter the number:";
cin>>num;
string binary;
