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 =...
In many graphics applications, a deterministic random hash provides the best source of random numbers. We evaluate a range of existing hash functions for random number quality using the TestU01 test suite, and GPU execution speed through benchmarking. We analyze the hash functions on the Pareto f...
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,"...
