纪念第一天令我头秃的一题。 In the main() function, after ModifyString(text) is called,
what’s the value of ‘text’?
int FindSubString( char* pch )
{
int count = 0;
char * p1 = pch;
while ( *p1 != '\0' )
{
if ( *p1 == p1[1] - 1 )
{
p1++;
count++;
}else {
break;
}
}
int count2 = count;
while ( *p1 != '\0' )
{
if ( *p1 == p1[1] + 1 )
{
p1++;
count2--;
}else {
break;
}
}
if ( count2 == 0 )
return(count);
return(0);
}
void ModifyString( char* pText )
{
char * p1 = pText;
char * p2 = p1;
while ( *p1 != '\0' )
{
int count = FindSubString( p1 );
if ( count > 0 )
{
*p2++ = *p1;
sprintf( p2, "%i", count );
while ( *p2 != '\0' )
{
p2++;
}
p1 += count + count + 1;
}else {
*p2++ = *p1++;
}
}
}
void main( void )
{
char text[32] = "XYBCDCBABABA";
ModifyString( text );
printf( text );
