Help: stdin to multi-dimensional array
I cant get out of this while loop at the beginning of my program. Just reading from stdin one char at a time and storing it into a multi-array. Need to fix it with in two hours.
Code:
#include <sys/wait.h>
#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <unistd.h>
#include <string.h>

int main(int argc, char* argv[]){
char character;
char temp;
int i = 0;
int c = 0;
int j = 1;
int y = 0;
char line[20][20];
int count=0;

printf("Please enter your exec file and its arguments and pres ENTER.\n");        

do{
    temp = getchar();
            
        if(temp == ' '){
            line[count][i] = '\0';
            i = 0;    
            count++;
      }
            else{
                 line[count][i] = temp;    
                 i++;
                        
            }    
                          printf("%c", line[count][i-1]);            
    }while(temp != '\0');

openssl_passwd

PASSWD(1)							      OpenSSL								 PASSWD(1)

NAME

       passwd - compute password hashes

LIBRARY

       libcrypto, -lcrypto

SYNOPSIS

       openssl passwd [-crypt] [-1] [-apr1] [-salt string] [-in file] [-stdin] [-noverify] [-quiet] [-table] {password}

DESCRIPTION

       The passwd command computes the hash of a password typed at run-time or the hash of each password in a list.  The password list is taken
       from the named file for option -in file, from stdin for option -stdin, or from the command line, or from the terminal otherwise.  The Unix
       standard algorithm crypt and the MD5-based BSD password algorithm 1 and its Apache variant apr1 are available.

OPTIONS

       -crypt
	   Use the crypt algorithm (default).

       -1  Use the MD5 based BSD password algorithm 1.

       -apr1
	   Use the apr1 algorithm (Apache variant of the BSD algorithm).

       -salt string
	   Use the specified salt.  When reading a password from the terminal, this implies -noverify.

       -in file
	   Read passwords from file.

       -stdin
	   Read passwords from stdin.

       -noverify
	   Don't verify when reading a password from the terminal.

       -quiet
	   Don't output warnings when passwords given at the command line are truncated.

       -table
	   In the output list, prepend the cleartext password and a TAB character to each password hash.

EXAMPLES

       openssl passwd -crypt -salt xx password prints xxj31ZMTZzkVA.

       openssl passwd -1 -salt xxxxxxxx password prints $1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a..

       openssl passwd -apr1 -salt xxxxxxxx password prints $apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0.
