ALLTRIM(STR(ASC(Z),2,1) java中str =str.subString(1, dim str as string*10,str=123,len(str)返回值为10,为什么?string*10是什么意思?为什么长度是10?还有,s=instr(3,aSsiAB,a,1)返回值为什么是5,不是不分大小写么,怎么不是2? char *p1=“abcd”,*p2=“ABCD”,str[50]=“xyz”；strcpy（str+2,strcat（p1+2,p2+1））；printf（“%s”,str）；请问输出结果? vb程序Dim a(1 To 20) As Integer,i As Integer,j As IntegerDim a(1 To 20) As Integer,i As Integer,j As IntegerPrivate Sub Command1_Click()Dim a(1 To 20) As IntegerFor j = 1 To 2For i = 1 To 10a(i) = Int(Rnd * 21) + 20Text1 = Text1 & Str(a(i))Next iTe IIF(LEN('$ '+allt(str(dJhj,12,2)))>9,LEFT(RIGH('$ '+allt(str(dJhj,12,2)),10),1), C++里的flag是什么意思?Status InputString(unsigned char *str) {int flag=0;unsigned char ch;str[0]=0;//接受输入while((ch=getchar())!=' ') {if(flag==1) {flag=2;break;}str[0]++;if(str[0]==255) flag=1;str[str[0]]=ch;}if(flag==2) {ErrorTip(Over str = str.replaceAll((.)\1+,$1);这一句代码什么意思? vf中的?str(t+1, 比如str(x=2) rockets是什么意思rockets 关于strcpy、strcat的用法原题：main(){char*p1,*p2,str[80]=onep1=two;p2=three;strcpy(str+2,strcat(p1+1,p2+2));printf(%s ,str);}onworee STR DB 21有这样一个定义,然后有一个CMP STR+1,2这样的比较具体的意义是什么? ROCKETS是什么意思? Rockets是什么 vf中+str(1,其结果是什么,
