简单d的betterC示例

import core.stdc.stdio;
import core.stdc.string;
extern(C):
int main ()
{
    int v= 10;int *p;
    printf("hh:%p", p);//
    p= &v;
    printf("hh:%p,%d\n", p,*p);
    enum string s1="akb",s2 = "haha";
    enum string s11=s1~s2;//bianyishi
    char[]s4,s3,s6;char*s5,s7;
    s3=cast(char[])s1;s4=cast(char[])s2;
    printf("s3:  %s\n", s1.ptr);
    s5=strcat(s3.ptr,s4.ptr);
    printf("%s,%s\n", s4.ptr,s5);
    printf("(s1) :  %d\n", s1.length);
    //s7=strchr(s5,7);
    s7=strdup(s5);//fuzhi dizhi
    //s7=strcpy(s5);//fuzhi dizhi
    printf("(s6):%p,%s\n", s7,s11.ptr);
    return 0;
}

有串的话,用枚:

import core.stdc.stdio;
extern(C):
void main()
{
    string m="fool!";//如果有串的计算,用`枚`.
    printf("%s\n", m.ptr);
}
