哈哈哈，我后台的和你前端的额一样，但是我写出来但是调试有问题  #include <stdio.h> int search(char *cpSource) { int iCount=0; while(*(cpSource+index)) { if(*cpSource =="\n") { return 0; } if(*cpSource == ".") { iCount++; } else{ if (iCount<2){ return 0; } else{ return iCount+ search(cpSource)-1; } } ++cpSource; } int main() { int a, b; char s[30000]; char restr; int count = 1; while(scanf("%d%d", &a,&b) != EOF){ for(i=0;i<a;i++) { gets(s);} for(int k=0;k<b;k++){ scanf("%d %s", &index, &restr); s[d+1]=restr; printf("%d", search(s)); return 0; } }
