C语言问题 read a line在代码中添加

该函数应该从指定的流中读取一行输入。更准确地说，它应该：从流中读取至多小于 size 的字符并将它们存储到 s 指向的缓冲区中。阅读在 EOF 或换行符后停止。如果读取换行符，则将其存储到缓冲区中。终止空字节（'\0'）存储在缓冲区中的最后一个字符之后。需要写主函数。

#include <stdio.h>

#include "get_string.h"

// print a line from stream using fgetc (only)
// reads  in at  most one less than size characters from stream and stores them into the
// buffer pointed to by s.  Reading stops after an EOF or a newline.  If a newline is read, it  is
// stored  into  the buffer.  A terminating null byte ('\0') is stored after the last character in the buffer.
void get_string(char *s, int size, FILE *stream) {

    // PUT YOUR CODE HERE

}


#include <stdio.h>
#include <ctype.h>
int main(void)
{
    char ch;

    ch = getchar();
    while (ch != '\0')
    {
        if (isalpha(ch))
            putchar(ch + 1);
        else
            putchar(ch);
        ch = getchar();
    }
    putchar(ch);    //打印换行字符
    return 0;
}

用这个玩

sprintf(s,"%.*s",len,szBuf);
这个函数也能赋值字符串
