下面是一个类的定义,试将程序补充完整。class A{String s;____int a=66;A(String sl){s=sl;}static int geta(){return a;}}
考题
假定有以下函数过程: Function Fun(S As String) As String Dim sl As String For i=1 To Len(S) s1=UCase (Mid(S,i,1))+s1 Next i Fun=s1 End Function则Str2=Fun("abcdefg”)的输出结果为( )。A.abcdefgB.ABCDEFGC.gfedcbaD.GFEDCBA
考题
下列给定程序中函数fun()的功能是;先将在字符串s中的字符按逆序存放到t串中,然后把s中的字符按正序连接到t串的后面。例如:当s中的字符串为ABCDE时,则t中的字符串应为EDCBAABCDE。请改正程序中的错误,使它能得出正确的结果。注意:不要改动main函数,不得增行或删行,也不得更改程序的结构。试题程序:include <conio.h>include <stdio.h>include <string.h>void fun (char *s, char *t ){int i,sl;sl=strlen(s);for (i=0;i<sl;i++)t[i]=s[sl-1];for (i=0; i<sl; i++)/*************found**************t [sl+i]=s [i];t [2*sl]-'\0';}main ( ){ char s[100], t[100];clrscr();printf("\nPlease enter string s: ");scanf ("%s", s);fun (s,t);printf ("The result is: %s\n",t);}
