Question

using c++ (NO STL libraries) create a program that will ask the user to enter two values (percent of free squares in the maze and the side dimensions of the maze) that will build a maze according to what the user enters. Along with asking the user these questions also ask the user the location they want to place the character inside the maze as well as the exit of the maze. In the maze free cells are blank. cells with obstacles are #. (You dont have to solve the maze)

Answer 1

#include <stdio.h>
#include <bits/stdc++.h>
using namespace std;
int main()
{

//declear all varible for maz dimenation, obstacles count and their position
int height,width;
int obsCount;
int x, y;
std::cout << "Please Enter height of maze " ;
cin>>height;
std::cout << "Please Enter width of maze " ;
cin>>width;
char **mat=new char*[width]; //declear maze
for( int i=0;i<height;i++){
mat[i]=new char[width]; //intialize maze
}
//intialize maze position at start with zero
for( int i=0;i<height;i++){
for(int j=0;j<width;j++){
mat[i][j]='0';
}
}
//ask user how many obstacles they want to put
std::cout << "At how many location you want to put obstacles " ;
cin>>obsCount;
if(obsCount>(width*height)){
cout<<"Too many position"; //if number of cells less than
return 0; //obstacles enteres exit
}
//take input for x,y position for each obstacles
for(int i=0;i<obsCount;i++){
std::cout << "Please enter x position of obstacles " ;
cin>>x;
if(x>height){
cout<<"x position is greater than width";
return 0;
}
std::cout << "Please enter y position of obstacles " ;
cin>>y;
if(y>width){
cout<<"y position is greater than width";
return 0;
}
mat[x-1][y-1]='#'; //put # at that position with one lower index
//as array index is zero based
}
int ex,ey;
cout<<"Please enter exit of the maze";
cin>>ex;
cin>>ey;
mat[ex-1][ey-1]='E';
//print maze
for( int i=0;i<height;i++){
for(int j=0;j<width;j++){
cout<<mat[i][j]<<" ";
}
cout<<"\n";
}
return 0;
}

output

Please Enter height of maze 4
Please Enter width of maze 5
At how many location you want to put obstacles 3
Please enter x position of obstacles 1
Please enter y position of obstacles 3
Please enter x position of obstacles 3
Please enter y position of obstacles 2
Please enter x position of obstacles 4 2
Please enter y position of obstacles 4
Please enter exit of the maze4 5
