通过与指针数组下循环 [英] C for loop through array with pointers

问题描述

我是新的C，但我在Java和Android体验。
我在for循环有问题。它永远不会结束，只是继续下去。

I'm new to C but I have experience in Java and Android. I have a problem in my for loop. It will never end and just go on and on.

char entered_string[50];
char *p_string = NULL;

gets( entered_string );

for( p_string = entered_string; p_string != '\0'; p_string++ ){
    //....
}

我知道，得到的是不安全，不建议去precated但根据我的规格我不得不使用它。我用指针要通过每个元素循环。

I know that gets is unsafe, not recommended and deprecated but according to my specs I have to use it. I want to loop through each element by using pointers.

推荐答案

您测试应该是 * p_string ='\\ 0';！

p_string 是一个指针，你的循环检查，如果指针！='\\ 0'。你有兴趣，如果该值！='\\ 0'，并用让你不得不取消对它的引用了指针的值* 。

p_string is a pointer, and your loop is checking if the pointer is != '\0'. You're interested in if the value is != '\0', and to get the value out of a pointer you have to dereference it with *.
