c中fgets与strlen fgets函数从文件读取'\n'并存储,在'\n'后再增加一个'\0'构成字符串。 但fgets函数需要指定读入的字符数,如果指定了n,则最多只能读取n-1个。fgets在读取了n-1个字符、读到了'\n'或遇到了EOF三种情况之一时都结束读取。 验证代码如下: #include <stdio.h> #include <string.h> #define...
fgets() function in C The standardClibrary also provides us with yet another function, thefgets()function. The function reads a text line or a string from the specified file or console. And then stores it to the respective string variable. Similar to thegets()function, fgets also terminates...
读入结束后,系统将自动在最后加'\0',并以str作为函数值返回。原型是char *fgets(char *s, int n, FILE *stream); 同时注意scanf函数和gets函数混用时的注意事项: 1、gets在scanf前调用,这种调用一般不会出现什么问题,可以正常输入。 2、scanf在gets前调用,这种情况就会出现问题,当输入完scanf中的变量时,运行...

The array str will contain the newline character too in case it is found. If no error occurs, a null character is written at the end of str. It is defined in <cstdio> header file. fgets() Parameters str: Pointer to an character array that stores the content of file. count: Maximum...
