Fucking C

Why it doesn't show me strings like "  a"?
Why is the while loop in the trim function bugged (if I input 2 chars the next input length can't be less than 2)?

#include <stdio.h>

#define MAX 1001

int getLine(char s[], int length){ // returns 1 or 0

    int i, qttWord = 0; //qttWord = counter of letters for s[]
    int c; // c = getchar()

    /*Reads the input and puts it into s[], then, verifies if the input is just \n,
    * if so, returns 0(i), if not, puts '\0' at the end of the string.
    */
    for (i = 0; i < length-1 && (c = getchar()) != EOF && c != '\n'; ++i){
            s[i] = c;
            ++qttWord;

    }
    if (i == 0){
        return 0;
    } else if (c == '\n'){
        ++i;
        s[i] = '\0';

    }
    /*Verifies if the string is just ' ' or '\t'
    * if so, returns 0
    */
    char flag = '\0';
    for (i = 0; i < qttWord && flag != '1'; ++i){
        if (s[i] == ' ' || s[i] == '\t'){
            flag = '0';
        } else{
            flag = '1';
        }
    }
    if (flag == '0')
        return 0;

    return qttWord;
}
void trim(char s[], int length){

    char s2[MAX];
    int i, qttWord = 0;

    /*while (s[length] != '\0'){
        ++length;
    }
    printf("length:%d\n", length);*/
    for (i = 0; i < length; ++i){
        if (i < length-1){
            if (s[i] == ' ' && s[i+1] != ' '){
                s2[i] = s[i];
                ++qttWord;
                printf("1:%d\n", s2[i]);// if true prints "1" and the character(' ')
            }
        }
        if (s[i] != ' '){
            s2[i] = s[i];
            ++qttWord;
            printf("0:%d\n", s2[i]);//if true prints "0" and the character
        }
    }
    s[0] = '\0';
    s2[qttWord] = '\0';

    for (i = 0; i < qttWord; ++i){
        s[i] = s2[i];
    }
    s2[0] = '\0';
}

int main(){
    char line[MAX];
    int lgh = 0;

    while ((lgh = getLine(line, MAX)) != 0){
        trim(line, lgh);
        printf("%s\n", line);
        line[0] = '\0';
        lgh = 0;
    }
    return 0;
}

EAT SHIT AND DIE CRETIN.

The fact that you use it pejoratively is damning in its own way, besides, and an argument on itself, closet homophobe.
Conclusion does not follow from premises.  Prove to me that such behaviour actually hurts homosexuals.

And the hundreds of grown-up versions of you on the Internet.
FUCK OFF AND DIE.

And you still don't understand what free speech entails.
It entails that anyone may be criticized by anyone else, and that anyone may say discriminatory jokes to their heart's content.

Fuck off, and come back when you are further into puberty, ``please''.
FUCK OFF AND DIE YOU COCK SUCKING CRETIN I FUCKING HATE YOU.
