need to read multiple inputs.

[childofthehorn]

Okay, so I can get this to read the first line of a txt document. I just can't figure out how to get it to read the next lines. I have to use "user_input " in a function. The wait function just waits until the user hits enter. The text document has 11 lines of code. I know this is a total newb question, but I am baffled. The function gets called at the begining of the file.

int file_run(void){
    char buffer[255];
    ifstream command_input_file;
    command_input_file.open("p3test.txt", ios::in);
    command_input_file.getline(buffer, 255);
    if(command_input_file == NULL){ return 0;};
    strcpy(user_input,buffer);
    wait();
    return 0;
 

HERE IS A PART OF MY CODE -SMALL PART:

int parse_command_line(void)
{                if(COMMANDS_FROM_FILE == 1){
                file_run();}
 
                if(COMMANDS_FROM_FILE ==0){
                cout << "Enter the Commmand: \n";
                cin.getline(user_input,' ');
                }
                // deliminates spaces and uses to separate tokens
                character_string = strtok(user_input," ");
                //compares the length of the string to allowable amount of characters.
                if( (strlen(user_input)) >= MAX_CMD_LINE_LENGTH){
                        cout << "Please Use " << MAX_CMD_LINE_LENGTH << " Characters or Less.\n";
                        return 0;}
                //cout << "Your Tokens Are: \n \n";
                j = 0;
                //This continues to process each character in the string until it reaches the end.
                while(character_string != NULL)
                { //Analyzises each character in the string, one at a time.
                    //character[j] = character_string;
                    strcpy(cStrings[j],character_string);
                    //error case if there are more than the 10 allowable tokens.
                    if(j > (MAX_TOKENS_ON_A_LINE)-1){
                        cout << "Please Enter " << MAX_TOKENS_ON_A_LINE << " Tokens or Less.\n";
                         return 0;
                    }
                    //cout << character[j] << endl;
                    j = j + 1;
                    character_string = strtok(NULL, " ");
                }  
 
if

you could have two seperate functions, one which opens the file and another which reads lines of text, e.g.

#include <fstream.h>
#include<iomanip.h>
ifstream command_input_file;
void file_open()
{
    command_input_file.open("p3test.txt", ios::in);
    if(! command_input_file)
      {
          cout << " error opeing file " << endl;
          exit(-1);
         }
}
 
int file_run(void){
    char buffer[255];
    command_input_file.getline(buffer, 255);
    if(command_input_file == NULL){ return 0;};
    strcpy(user_input,buffer);
    wait();
    return 1;  // return 1 for OK 0 for fail
}
 

you keep calling file_run() until it returns 0

Thank You very much it was very helpful!

Doing this fixed it all:

    if(COMMANDS_FROM_FILE == 1){
                    if(k == 1){ 
                        file_open();
                        k = k-1;
                    }
 
                file_run();}
 
    if(COMMANDS_FROM_FILE ==0){
            cout << "Enter the Commmand: \n";

I had been staring at this for a couple hours yet.....
