还有什么要注意的-蛮力字符串匹配#include<stdio.h> #include<string.h> int cmp(char a[],char b[],int k)//a[]是要匹配的字符串,b[]是原来字符串 { int n,m,j,i,num=0; m=strlen(a);n=k; for(i=0;i<=n-m;i++) { j=0; while(j<m&&a[j]==b[i+j]) j=j+1; if(j==m){num++;continue;} } return num; } struct dictionary { char dict[17]; long dollar; }d[1001]; void main() { long value=0; int i,k,n,m; int wordlenth[1000],num,j=0; char desc[5001]; scanf("%d %d",&m,&n); for(i=0;i<m;i++) { scanf("%s",d[i].dict); scanf("%d",&d[i].dollar); } while(n--) { i=0; while((desc[i]=getchar())!='.')// this while used to input the description i++; k=i; for(i=0;i<m;i++) { value+=cmp(d[i].dict,desc,k)*d[i].dollar; } printf("%d\n",value); value=0; } } Followed by: Post your reply here: |
