This function is from thectype.hfile which needs to be included in the program. ctype.h - isalnum() function Example in C #include <stdio.h>#include <ctype.h>intmain(){// Defining the type of variables and initializing themchara='A';charb='@';// condition to prove that the value...
1.交互窗口处执行:这个时候由于python的强制缩进,因此想要结束函数的定义只需要按两下enter即可. 2.在.py文件中编写,结束函数只需要不再缩进即可调用函数方法相同,把函数名及参数写上就可以了,如果有返回值可以r=functiona(var1)附:测试代码(python3运行通过)#-*-coding:utf-8-*-#author:zfxcxdefpt():print(...
In this example, the character a is checked using the isalnum() function. Since a is an alphabetic letter, the function returns a non-zero value, indicating it is alphanumeric. Open Compiler #include <stdio.h> #include <ctype.h> int main() { char ch = 'a'; if (isalnum(ch)) { ...
