请高手告诉我下面代码中的几行是什么意思(这是个完整的代码)
#include <stdio.h>#include <conio.h>void main(){ char ch,nch; int count; int k; printf("Please input a string with a # in the end.\n"); scanf("%c",&ch); [color=#FF0000]while(ch != '#') { if(ch >= '0' && ch <= '9') { count = ch-'0'+1; scanf("%c",&nch); for(k=0;k<count;k++) printf("%c",nch); } else printf("%c",ch); printf(" "); scanf("%c",&ch); }[/color] printf("#\n"); getch();}
