C计算字符串长度

Question

int strlength(const char *myStr){
    //variable used for str length counter
    int strlength = 0;
    //loop through string until end is reached. Each iteration adds one to the string length
        while (myStr[strlength] != '\0'){
            putchar(myStr[strlength]);
            strlength++;
        }

    return strlength;
}

为什么这不能按预期工作？我只想找到一个字符串的长度。

来自对另一个答案的评论:

I am using fgets to read in a string. and i have checked to make sure that the string that was typed was stored correclty

在这种情况下，存储了一个尾随换行符，因此您的函数会计算

strlength("hello\n")

代码是正确的，您只是没有将您认为应该传递的输入传递给它。
