需要准备的材料分别有：电脑、C语言编译器。
1、首先，打开C语言编译器，新建一个初始.cpp文件，例如：test.cpp。
2、在test.cpp文件中，输入C语言代码：
char *pKey = "AA1F1905A8F3E4D3C3C536FE615C93BC";
for (int i = 0; i < strlen(pKey) - 1; i += 2) {
printf("0x%c%c
", pKey[i], pKey[i+1]);
}
3、编译器运行test.cpp文件，此时成功将字符串数组转为了16进制的形式进行了输出。
#include <stdio.h>
#include <string.h>
#include <malloc.h>
int main(void)
{
char *pKey = "AA1F1905A8F3E4D3C3C536FE615C93BC";
int n=strlen(pKey)/2,i;
char *Key=(char *)malloc(sizeof(char)*n);
for(i=0;i<n;++i)
{
sscanf(pKey+2*i,"%2X",Key+i);
}
for(i=0;i<n;++i)
{
printf("%#02hhX ",Key[i]);
}
return 0;
}
