    Question Binary,Hexadecimal to Text

    Hey,

    I am pretty new to C++ and have been known to be a bit of an idiot...anyway.

    I am trying to write a simple dos based program to convert normal text to hex or binary and visa versa.

    Basically I want to be able to input text and convert it to hex/bin or input hex/bin and convert it to text.

    However I am at a loss of an short way to do this without typing out the ASCII character code chart..

    I was thinking i would need to store the values in an array but i haven't yet mastered this either.

    So I guess I am asking is there a simple way to do this ? I am not asking you to write the program for me just give me some direction as to how to do it....

    Thanks heaps.

    (sorry if this has been posted a billion times before I searched but didn't find what I wanted.)

    yes... unregistered has been an idiot for more times than i can remember

    a string in c is simply an array of char followed by a 0
    PHP Code:
    #include <stdio.h> 
    #include <math.h>
    int main() {
    char *temp "the word";
    char x;
    while (
    x=*temp++) {
       
    printf("%x",x);
    for (
    int i=7;i>=0;i++)
         
    printf("%d",(x/(char)pow(2,i))%0);

      }

    this prints the hex part then the decimal right after. take what you need from this
