C 程序未接收到所有输入

Question

我目前正在编写一个程序，该程序应该接收来自文本文件的输入并输出有关文本的统计信息，例如字母数量、单词大小、它们出现的频率以及每个单词出现的次数。但是，每次我运行该程序时，它都不会读取所有文本。它只读前几个字。这是一些示例文本:

1
你好，我叫鲍勃
我住在加拿大

它只会显示“你好，我的名字是”。好像把最后一个字给截断了。我使用编译器中文本文件的输入重定向从文件导入文本(我必须这样做)。

数字表示应该读取多少行。我应该怎么做才能纠正我的问题？我对编程很陌生，所以我确信它是基础知识。

int wordLengthAnalysis(char [][MAX_LINE_LENGTH], int lineTotal, int wordLength);
void wordAnalysis(char [][MAX_LINE_LENGTH], int lineTotal);


int main (void){

    int lineTotal = 0;
    int wordSize = 0;
    char text[lineTotal][MAX_LINE_LENGTH];
    char n[1] = {0};

    fgets(n, 800, stdin);
    lineTotal = n[0] - '0';


    for(int i = 0; i < lineTotal; i++){}
        fgets(text[i], MAX_WORD_LENGTH, stdin);
    }

    printf("\n***Letter count analysis***\n");
    letterAnalysis(text, lineTotal);

    printf("\n***Word length analysis***\n");

Answer 1

for(int i = 0; i < lineTotal; i++){}
    fgets(text[i], MAX_WORD_LENGTH, stdin);
}

这应该是 MAX_LINE_LENGTH。
