下面是C实现,以显示在C中使用strndup()函数: // C program to demonstrate strndup()#include<stdio.h>#include<string.h>intmain(){charsource[] ="GeeksForGeeks";// 5 bytes of source are copied to a new memory// allocated dynamically and pointer to copied// memory is returned.char* target = strndup(source,5);printf("%...
definitions. Instead, we need to compile the code and then run themainmethod of specific objects. The next step is to runscalac(N.B. “scalac” with a “c”, not “scala”) onPersonApp.scala. The name scalac is short forScala compiler. Do the following steps in the/tmp/tutorial...
下面是一个简单的C程序,用于显示strtok_r()的用法: // C program to demonstrate working of strtok_r()// by splitting string based on space character.#include<stdio.h>#include<string.h>intmain(){charstr[] ="Geeks for Geeks";char* token;char* rest = str;while((token = strtok_r(rest,"...
