Why is it colliding

[Deanmon]

i made a program and i cant find root of problem. Code is

#include<iostream>
#include <cstdlib>  
#include<conio.h>
using namespace std;
int main(){
	int r = 5, c = 5;;
	char player = 'P';
	char choice = 0;
	int dr = 1, dc = 1;//diamond in row //dimond in column
	int dr2 = 4, dc2 = 4;
	int br = 2, bc = 2;
	int br2 = 4, bc2 = 1;
	int pr = 0, pc = 0;
	int score = 0;
	char d = 'D';
	char d1 = 'D';
	char b = 'B';
	char b1 = 'B';
	int p = 0;
	


	while (score != 25){
		if (pc == dc && pr == dr) {
			score = score + 1;
			int newdc = rand() % 5;
			int newdr = rand() % 5;
			while (newdc == dc || newdc == bc || newdc == br) newdc = rand() % 5;
			while (newdr == dr || newdr == bc || newdr == br) newdr = rand() % 5;

			dc = newdc;
			dr = newdr;


			int newbc = rand() % 5;
			int newbr = rand() % 5;
			while (newbc == bc || newbc == dc || newbc == dr || newbc == dr2 || newbc == dc2) newbc = rand() % 5;
			while (newbr == br || newbr == dc || newbr == dr || newbr == dc2 || newbr == dr2)newbr = rand() % 5;
			br = newbr;
			bc = newbc;

			


		}
		if (pc == dc2&& pr == dr2) {
			score = score + 1;
			int newdc2 = rand() % 5;
			int newdr2 = rand() % 5;
			while (newdc2 == dc2 || newdc2 == bc || newdc2 == br) newdc2 = rand() % 5;
			while (newdr2 == dr2 || newdr2 == bc || newdr2 == br) newdr2 = rand() % 5;
			dc2 = newdc2;
			dr2 = newdr2;

			int newbc = rand() % 5;
			int newbr = rand() % 5;
			while (newbc == bc || newbc == dc || newbc == dr || newbc == dr2 || newbc == dc2) newbc = rand() % 5;

			br = newbr;
			bc = newbc;

		for (int i = 0; i < r; i = i + 1){



			for (int j = 0; j < c; j = j + 1){

}

when i move the player to 4x4 diamond the one in the last row. it collides and game gets over. i cant figure out why. i dried run it and i cant find the problem. And second problem i am facing is when i pick a diamond it randmoize 1st bomb.it should also happen with second bomb. When i add the same random fucntion as i did for bomb1 the program just dont run. it hangs. I will be really thankful for your help.

I think what's happen is that when you take the diamond the bomb happens to be moved right were the player is so you lose then right away.
