Question

用C程序编写一个函数，将一个字符串中的元音字母复制到另一个字符串，然后输出

Answer 1

#include <stdio.h>
#include <stdlib.h>

char vowel[]={'A','E','I','O','U','a','e','i','o','u'};

char IsGetVowel(char s)
{
int l;
for (l=0;l<sizeof(vowel);l++)
{
if(s==vowel[l])
{
break;
}
}
if(l<sizeof(vowel))
{
return s;
}
else
{
return '\0';
}
}

unsigned __int32 ScanVowel(char* Source,char* Target)
{
char *p,*s,tmp;
unsigned __int32 R=0;
p=Source;
s=Target;
while(*p!='\0')
{
tmp=IsGetVowel(*p++);
if(tmp!='\0')
{
R++;
*s++=tmp;
}
}
*s='\0';
return R;
}

int main(int argc, char* argv[])
{
char Str1[32],Str2[32];
scanf("%s",Str1);

ScanVowel(Str1,Str2);

printf("%s\n",Str2);
system("Pause");
return 0;
}
