Xin hướng dẫn cách sử dụng Dev-C++ , hix hix
Mình có viết 1 doạn :
Quote:
#include<conio.h>
#include<stdio.h>
#include<stdlib.h>
#include<math.h>
#include<iostream.h>
void main()
{
clrscr();
int p[5],q[5];
p[1]=p[2]=q[1]=q[3]=1;
p[3]=p[4]=q[2]=q[4]=0;
cout<<"P Q (P and Q) (P or Q) (P xor Q) (P -> Q) (P <-> Q) ";
for(int i=1;i<=4;i++)
cout<<"\n\n"<<p[i]<<" "<<q[i]<<" "<<(p[i]&&q[i])<<" "<<(p[i]||q[i])<<" "<<(!(p[i]==q[i]))<<" "<<((!(p[i]))||q[i])<<" "<<(p[i]==q[i]);
getch();
}
Viết trong TC thì khi nhấn CTRL + F9 thì chuơng trình chạy bình thường, hok có 1 lỗi nào , Nhưng khi vào trong Dev-C++ thì nó báo 1 đống lỗi
