下面是道改错题，答案是把for( i = strlen( t ); i!=0; i-- ) 改为
for( i = strlen( t )-1; i!=0; i-- )
但书上说strlen()的长度不是不包含\0吗，为什么还要减一？？
#include <stdio.h>
void fun( char t[] )
{
char c;
int i, j;
/**********found***********/
for( i = strlen( t ); i!=0; i-- )
for( j = 0; j < i; j++ )
if( t[j] > t[ j + 1 ] )
{
c = t[j];
t[j] = t[ j + 1 ];
t[j + 1 ] = c;
}
}
main()
{
char s[81];
printf( "\nPlease enter a character string: " );
gets( s );
printf( "\n\nBefore sorting:\n \"%s\"", s );
fun( s );
printf( "\nAfter sorting decendingly:\n \"%s\"", s );
}
