i need to code a function that converts an array of 64 bits into a hexadecimal value, the one is tested gives me correct value except for the last hexadecimal letter.
#include<stdio.h>#define MAX 1000 int main(){ char binaryNumber[MAX],hexaDecimal[MAX]; long int i=0; printf("Enter any hexadecimal number: "); scanf("%s",hexaDecimal);
[Code]...
So this is my current code, is there anyway I can reduce the size and use a main function to ask for input and a call function to do all the conversion and return it? I am confused for the past few days trying to figure it out and finally ended up here. Anyway can I write it as a something like this
Code:
int main() { //ask for user input hexadecimal into here and call a let's say hex2binary() function }
int hex2binary(...) { //an array with dynamic memory, malloc? and convert it and return values }
I don't really need the full code, just a simple instruction on how and where to start.
The program is supposed to convert a two digit hexadecimal number to its binary representation. My code runs without any problems but I do not know how to limit the user's input to two digits only. For example the person can input "1ABC" and the program will give the binary representation and I need it to only accept two digit only like for example "1A".
#include<stdio.h> #define MAX 1000 int main(){ char binaryNumber[MAX],hexaDecimal[MAX]; long int i=0; printf("Enter a two digit hexadecimal number: ");
Write a program in c++ to accept a number and convert this number into binary or hexa decimal or octal number according to the user choice using the concept of array.
I have a problem who must print the sentences who have lenght more than 20 characters. I dont know why, but it prints just the first words. Look what i made.
#include<stdio.h> #include<conio.h> int main()
[Code]....
For instance :
Give the number of sentences : 3
First sentence : I like the website bytes.com Second sentence : I like more the website bytes.com Third sentence : bytes.com
After I compile the program it should print the first two sentences.
I am making a program that takes the user's family names, their ages, and where they live. At the end I will be eventually averaging out their age and also printing the names of anyone who lives in Kansas.
I can't seem to get the Kansas part to work properly though.. When I execute the code, everything else works perfectly, but the Kansas part doesn't even print. Is there something different I need to do when strings are involved rather than integers/floats?
Code:
#include <stdio.h> int main () { /* variable definition: */

This program is supposed to compare 2 strings and print out a 1 if the characters match and a 0 if they dont. It compiles but doesnt give me the correct output.
Code: #include <stdio.h> #include <string.h> void func(); int main () { func(); return 0;
I need access to the string using the int and the int using the string. Or just direct access to one or the other. . . It's just confusing that they're technically mapped to one another but I can't really access either of them.
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)
I'm trying to write a program that takes input from the user (thats a char) and outputs it to the monitor in hex form.The program is meant to continuously take input from the user then output to the monitor in hex form until an EOF is detected this triggers the program to close.The following code does this except that I get a lower case 'a' at the end of each output.
example:
input from user: ABC output to monitor: 41 42 43 a
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....
Just working up for the google coding contest to start soon and have been practising some of the test questions however i make correct algorithms but my output is rejected because of the fact that my strings are printed on a new line so i wish to know a method to print strings using a printf statement or any other function on the same line ...
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.
Write the function itob(n,s,b) that converts the integer n into a base b character representation in the string s . In particular, itob(n,s,16) formats n as a hexadecimal integer in s .
Note that it says the result is formatted into a hexadecimal integer in the string s. Here is the example provided:
Code:
void itob(int n, char s[], int b) { static char digits[] = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"; int i, sign; if ( b < 2 || b > 36 ) { fprintf(stderr, "EX3_5: Cannot support base %d
[Code] ....
Why does digits array hold the full alphabet when the maximum digit for a hex number is f?
