The fgets() function is a powerful and versatile tool for reading data in C. It is simple to use, safe, and adaptable. However, it is important to understand its limitations and use it carefully to avoid common errors. You can use fgets() effectively and write robust C programs by adher...
C语言fgets和fputs函数的用法详解(以字符串的形式读写文件) C语⾔fgets和fputs函数的⽤法详解(以字符串的形式读写⽂件) fgetc() 和 fputc() 函数每次只能读写⼀个字符,速度较慢;实际开发中往往是每次读写⼀个字符串或者⼀个数据块,这样能明显提⾼效 率。 读字符串函数 fgets fgets() 函数⽤来...
The fgets function reads a string from the input stream argument and stores it in str. fgets reads characters from the current stream position to and including the first newline character, to the end of the stream, or until the number of characters read is equal to numChars - 1, ...
In this case, the contents of str are indeterminate. They may not even be null terminated. Example: How fgets() function works #include <iostream> #include <cstdio> using namespace std; int main() { int count = 10; char str[10]; FILE *fp; fp = fopen("file.txt","w+"); fputs...

The fgets function reads a string from the input stream argument and stores it in str. fgets reads characters from the current stream position to and including the first newline character, to the end of the stream, or until the number of characters read is equal to n – 1, whichever ...
In this chapter we will learn all the functions used on strings in C - gets(), fgets(), getline(), getdelim(), getchar(), puts(), putchar(), strlen() in C language.
```c char *fgets(char *str, int n, FILE *stream); ``` 其中,str 是指向存储读取字符串的缓冲区的指针,n 是缓冲区的 大小,stream 是指向要读取的文件或标准输入流的指针。fgets 函数 的返回值是指向缓冲区的指针,如果读取失败或到达文件末尾,则 返回 NULL。 c语言中的fgets与fputs函数 路漫漫其修远兮...
