c - 将字符串拆分为单词

Question

我有以下问题:

// Basically I am reading from a file and storing in local array.

char myText[100] = "This is text of movie Jurassic Park";

// here I want to store each work in to dictionary

st.insert(&myText[0]); // should insert "This" not till end of sentence.

// similarly for next word "is", "text" and so on.

如何用 C 语言做到这一点？

Answer 1

为此，您可以使用 strtok function :

char myText[100] = "This is text of movie Jurassic Park";
char *p;
for (p = strtok(myText," "); p != NULL; p = strtok(NULL," ")) {
    st.insert(p);
}

请注意，此函数通过在分隔符所在的位置添加 NUL 字节来修改它正在解析的字符串。
