I am facing a problem while compiling a program where the gets() function is used. #include<stdio.h> /*example of multi char i/p function*/ void main() { char loki[10]; gets(loki); printf("puts(loki)"); } The error I am getting is: warning: 'implicit d...

linux系统下,警告:warning: implicit declaration of function ‘gets’ [-Wimplicit-function-declaration] 和 war 字符数组 的英文名字是 char [] gets()函数的基本用法为:char *gets(char *s); 该函数的参数是一个字符数组,该函数的返回值也是一个字符数组。 linux下的代码如下: 1 #include <stdio.h> 2 ...
These days, gets is not a standard C library function. To explain in more detail: in modern C, if you write int main() { f(); } int f() { return 0; } you will typically get a message like "implicit declaration of function 'f' is invalid in C99". Once upon a time, i...
函数声明不明确。 引起这个问题的原因: 1,没有包含该函数的头文件。 解决办法: 把函数对应头文件include。 查找函数所在头文件的方法: man <function name> 例如,查找printf函数:man printf 在手册中找到对应头文件。
