将文本文件的每一行转换为数组c

Question

I'm trying to take input from a text file, and then reverse each line, and output back into a different text file. For some reason, the program only dos this for the first line, and does not move onto the second line. I don't get this because it should keep going until it hits EOF.

Answer 1

If the file doesn't end with a newline, you'll never print the last line, because you only call reverse(array) when you read the newline character.

You can solve this by calling it again after the while loop is done.

int  main() {
    char temp;
    char  array[80] = "";
    int count = 0;
    temp = getchar();  //Start on first Character
    while (temp != EOF) {   //loop through the entire file
        if (temp == '\n') {  //If it is the end of a line
            reverse(array);   //Print out the reversed line
            memset(array,0,80);  //clear the array
            count = 0;  //reset count
            temp = getchar(); //Advance getchar
        }
        else {  //If it is not the end of the line
            array[count] = temp;  //Store the char in the array
            count++;   //advance count
            temp = getchar();   //advance getchar
        }
    }
    if (count > 0) {
        reverse(array);
    }
    return 0;
}
