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');

                          printf("%c", line[count][i-1]);            
    }while(temp != '\0');

change the line "char temp;" to "int temp;", this is because EOF value is '-1' and getchar() returns an unsigned int constant.
