Using C++

You are asked to create a 1D terrain for a side-scrolling game. The 1D terrain consists of x blocks (think minecraft). Each block is assigned a random height between l feets and h feets. We assume that both l and h are greater than or equal to 0 and less than or equal to 64. l is always less than or equal to h.

Code

#include  #include  #include  

using namespace std;

const int x = 15; const int l = 2; const int h = 10; 

int main() {

// length i.e. total number of blocks // lowest height (in feet) of a block // highest height (in feet) of a block  

srand(time(NULL)); int height[x]; // 1D array to store the heights of

 // different blocks  

for (int i=0; i

}

 cout  
 pprint_height(height, x); } 
 
The code shown above stores block heights in a 1D array. It randomly assigns heights to different blocks. Function print_height can be used for debugging. It prints the contents of the 1D array. Functions get_max is used to find the highest point in the terrain. pprint_height displays the terrain in a graphical manner (see below). Function get_max returns an random integer between two values.
 
Part 1 - What to do?
 
You are asked to complete the following functions
 
int get_random(int l, int h) { } 
 
int get_max(int height[], int sz) { } 
 
void print_height(int height[], int sz) { } 
 
void pprint_height(int height[], int sz) { } 
 
Desired Output
 
When you compile and run the completed program, you will get the following output.
 
$ g++ terrain.cpp $ ./a.out Print raw: 933442285727645 Print max height: 9
 
Pretty print:
 
 
Part 2 - Reading and writing to a file
 
Now add the following two command line options:
 
 -s; and
 
 -l. When we execute the program as follows: $ ./a.out -s it saves the heights (all 10 of them) to a text file heights.txt. Similarly when we execute the program as follows: $ ./a.out -l it loads the block heights (all 10 of them) from a text file heights.txt.
 
Extra
 
Can you change the code such that the height of any two adjacent blocks do not vary more than (h-l)/4. Also that at least one block has height greater than 1-l/9.
