字符串删除某个字符

L1-011 A-B (20分)(C语言)

任宣辰: 我自己写了一段比较抽象的 #include <bits/stdc++.h> using namespace std; int main(){ string A,B; int ASC[256] = {0}; getline(cin, A); getline(cin, B); int AL = (int)(); int BL = (int)(); for(int i = 0; i < BL; i++) ASC[(int)(unsigned char)B[i]]++; for(int i = 0; i < AL; i++){ if(ASC[(int)(unsigned char)A[i]] == 0) cout << A[i]; else continue; } return 0; }
