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;
}

Why the fuck are you writing the function getLine? Don't you know the stdio.h library you've included contains dozens of options for you to do exactly what you did just not as retarded?

Also stop using camel case you nigger.
