#include <stdio.h>

void reverse( const char *const sPtr );

int main( void )
{
char sentence[ 80 ];

printf( "Enter a line of text:        " );

gets( sentence );

printf( "\nThe line printed backward is:\n" );
reverse( sentence );

return 0;
}

void reverse( const char *const sPtr )
{
if( sPtr[0]=='\0' ){
return;
}
else {
reverse( &sPtr[ 1 ] );

putchar( sPtr[ 0 ] );
}
}

比如我输入We！输出的是 !eW,但过程理解不了，是否可以详细讲解下这个递归过程，谢谢
