假设我有一个段落作为这样的输入

C is an imperative procedural language. It was designed to be compiled using a relatively straightforward compiler, to provide low-level access to memory, to provide language constructs that map efficiently to machine instructions, and to require minimal run-time support. Despite its low-level capabilities, the language was designed to encourage cross-platform programming

如何在不获取整个段落的情况下逐字获取输入？

Answer 1

当用户按下回车键时，输入流将保存整个输入 block 以及回车符。从那里，只需根据您的喜好阅读或格式化它即可。

就您而言，只要您不关心标点符号，strtok 就可以正常工作。

#include <stdio.h>
#include <string.h>

int main(void) {

    char Stream[1024] = {0};
    char* TokenPointer = 0;
    const char Token[] = " ";

    fgets(Stream,sizeof(Stream),stdin);
    TokenPointer = strtok(Stream, Token);
    while(TokenPointer != 0)
    {
        puts(TokenPointer);
        TokenPointer = strtok(0,Token);
    }
    return 0;
}
