十进制转十六进制的两种方法 莫名其妙指针
#include<stdio.h>
int main()
{
int n;
scanf("%d",&n);
printf("%X\n",n);
return 0;
}
莫名其妙的指针方法
#include<stdio.h>
main()
{
int a[10];
int p;
p=a;
for(int i=0;i<10;i++)
{
scanf("%d",a+i);
}
for(int i=0;i<10;i++)
{
printf("%p ",(p+i));
}
return 0;
}
附加十进制转十六进制
#include <stdio.h>
#include <string.h>
#include <math.h>
int main()
{
char strHex[8];
int i = 0, len = 0, temp = 0;
__int64 nDec = 0;
gets(strHex); len = strlen(strHex); for (i = 0; strHex[i] != '\0'; ++i) { switch(strHex[i]) { case 'A': temp = 10; break; case 'B': temp = 11; break; case 'C': temp = 12; break; case 'D': temp = 13; break; case 'E': temp = 14; break; case 'F': temp = 15; break; default: temp = strHex[i]-'0'; break; } nDec += (temp*pow(16,len-1-i)); } printf("%I64d",nDec); return 0; }
