Question

I have a C program that reads from a txt file. The text file contains a list of words, one word per line. What I want to do is get the words from the text file and print them as one sentence/paragraph, however, when I try to print them, they still print one word per line.
I am storing the words in a 2d char array as I read them from the file. What I think is happening is the array copies the newline char from the txt file, is that correct? and if so, how do I add the word into the array without the new line char?

    while(fgets(line,20,lineRead)!=NULL)
    {
        for(j = 0; j < 20;j++)
        {            
            message[k][j]= line[j];

        }
        printf("%s", message[k]);
    }

I tried a few while loops with no success:

while(line[j] != ' ')        
while(line[j] != NULL)       
while(line[j] != EOF)      
while(line[j] != ' \')

I’m learning C so please be specific in my error. I want to understand what I’m doing wrong, not just get an answer.

Thank you!

You could simply change your for loop to be:

for(j = 0; j < 20 && line[j] != '\n';j++)
{            
    message[k][j]= line[j];
}
if(j < 20)
    message[k][j] = '\0';
