I have 102 Errors, may i know why it is this case? :O Any solution to this? Code: #include<stdio.h> #include<iostream> #define MAX 30 using namespace std; typedef struct pqueue { char str[MAX]; int priority; pqueue* next; }pqueue; int enqueuepriority(pqueue *&pq, char str[MAX], int priority) { if(priority>0) { pqueue *p=(pqueue*)malloc(sizeof(pqueue)); for(int i=0;i<MAX;i++) p->str[i]=str[i]; p->priority=priority; p->next=pq->next; pq->next=p; return 1; } else return 0; } char* dequeue(pqueue *&pq) { pqueue *p; if(pq->next!=NULL) { p=pq->next; pq->next=pq->next->next; return p->str; } else return ""; } int main() { cout<<"(1) Enqueue (single)"<<endl; cout<<"(2) Enqueue (multiple)"<<endl; cout<<"(3) Dequeue (single)"<<endl; cout<<"(4) Dequeue (all)"<<endl; cout<<"(5) Quit"<<endl; int re=0,t=1; static char* str=new char[MAX]; int priority=0; pqueue *pq=(pqueue*)malloc(sizeof(pqueue)); pq->next=NULL; while(re!=5) { cout<<"Choose an action:"; cin>>re; switch(re) { case 1: cout<<"Enter a name to save and its priority"<<endl; scanf("%s%d",str,&priority); if(enqueuepriority(pq,str,priority)) break; else { cout<<"INPUT ERROR!!"<<endl; break; } case 2: cout<<"Enter names to save and their priority. Enter “done” to quit"<<endl; do { scanf("%s",str); if(strcmp(str,"done")!=0) { scanf("%d",&priority); enqueuepriority(pq,str,priority); } else t=0; }while(t==1); break; case 3: str=dequeue(pq); if(str=="") cout<<"NULL"<<endl; else printf("%s\n",str); break; case 4: while(pq->next!=NULL) { printf("%s\n",dequeue(pq)); } break; case 5: break; default: cout<<"INPUT ERROR!!"<<endl; break; } } delete [] str; return 0; }
Re: I have 102 Errors, may i know why it is this case? Try this, its running Code: #include<stdio.h> #include<iostream.h> #include<stdlib.h> #include<string.h> #define MAX 30 typedef struct pqueue { char str[MAX]; int priority; pqueue* next; }pqueue; int enqueuepriority(pqueue *&pq, char str[MAX], int priority) { if(priority>0) { pqueue *p=(pqueue*)malloc(sizeof(pqueue)); for(int i=0;i<MAX;i++) p->str[i]=str[i]; p->priority=priority; p->next=pq->next; pq->next=p; return 1; } else return 0; } char* dequeue(pqueue *&pq) { pqueue *p; if(pq->next!=NULL) { p=pq->next; pq->next=pq->next->next; return p->str; } else return ""; } int main() { cout<<"(1) Enqueue (single)"<<endl; cout<<"(2) Enqueue (multiple)"<<endl; cout<<"(3) Dequeue (single)"<<endl; cout<<"(4) Dequeue (all)"<<endl; cout<<"(5) Quit"<<endl; int re=0,t=1; static char* str=new char[MAX]; int priority=0; pqueue *pq=(pqueue*)malloc(sizeof(pqueue)); pq->next=NULL; while(re!=5) { cout<<"Choose an action:"; cin>>re; switch(re) { case 1: cout<<"Enter a name to save and its priority"<<endl; scanf("%s%d",str,&priority); if(enqueuepriority(pq,str,priority)) break; else { cout<<"INPUT ERROR!!"<<endl; break; } case 2: cout<<"Enter names to save and their priority. Enter “done” to quit"<<endl; do { scanf("%s",str); if(strcmp(str,"done")!=0) { scanf("%d",&priority); enqueuepriority(pq,str,priority); } else t=0; }while(t==1); break; case 3: str=dequeue(pq); if(str=="") cout<<"NULL"<<endl; else printf("%s\n",str); break; case 4: while(pq->next!=NULL) { printf("%s\n",dequeue(pq)); } break; case 5: break; default: cout<<"INPUT ERROR!!"<<endl; break; } } delete [] str; return 0; }
Re: I have 102 Errors, may i know why it is this case? Try this, its running Hi expert, thanks for the amendment! Would like to ask i got the error is it because i did not specify #include<string.h>? However when i tried to preview your code, I got error like "Error 1 error C1083: Cannot open include file: 'iostream.h': No such file or directory"? & " 2 IntelliSense: cannot open source file "iostream.h"?
