Help with Hexadecimal Conversion

[f4ichick02]

I am trying to create a program where when I enter a character, after the user presses enter it displays the hexadecimal of it. I am seeming to have problems finding how to do it. Any suggestions? Thanks

Something like this?

#include <stdio.h>

int main()
{
    char c = 10;
    printf("%x\n", c);
    return 0;
}

That's the easy way. If you want to write a function like toHex() that's a whole different ballgame.

edit: maybe you are having problems with the input as well?

char c;
scanf("%c", &c);

Is that what the %x does?? Converts it into a hexadecimal. Here is what I have so far..

#include <stdio.h>

main()
{       char c[5]; 
                           
puts("Enter Character:");
        while(gets(c) != NULL)   
        {        puts(c);        
                 printf("\n");     
        }
}

%x is just another format specifier like %d, %f etc.it is used for hexadecimal numbers.it gives the hexadecimal form of the corresponding argument.
for eg.

int i=15;
printf("%x",i);

will output F
Similarly %o is used for octal.
