去掉fgets的换行符

要去掉fgets函数录入的字符串末尾的换行符'\n'，可以使用一个自定义的函数来实现。可以定义一个名为"removeNewline"的函数，接受一个字符串作为参数，然后遍历字符串找到末尾的换行符'\n'，将其替换为字符串结束符'\0'即可。这样就可以去掉fgets函数录入的换行符。代码示例如下：

void removeNewline(char *str) {
    int len = strlen(str);
    if (len > 0 && str[len-1 == '\n') {
        str[len-1 = '\0';
    }
}

使用这个函数可以快速去掉fgets函数录入字符串末尾的换行符'\n'。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
