我有一个接受动态多维数组(初始化为 0)作为参数的函数,并且我试图在我的函数中修改数组中的某些值。
接受数组作为参数的函数应该模拟两个骰子的滚动并将频率分布输出到我创建的初始化为零的数组。
它的代码如下:
#include <iostream>
#include <cstdlib>
using namespace std;
int** rollDie(int numRolls, unsigned short seed, int** &rollarray)
{
srand(seed);
int side1, side2;
while (numRolls > 0)
{
side1 = 1 + rand() % 6;
side2 = 1 + rand() % 6;
rollarray[side1][side2]++;
numRolls--;
}
return rollarray;
}
int** initializeArray(void)
{
int i, j;
int** m = new int*[6];
for (i = 0; i < 6; i++)
m[i] = new int[6];
for (i = 0; i < 6; i++)
for (j = 0; j < 6; j++)
m[i][j] = 0;
return m;
}
int main()
{
int numRolls;
unsigned short seed;
int ** a = initializeArray();
cout << "rolls?\n";
cin >> numRolls;
cout << "seed?\n";
cin >> seed;
int ** b = rollDie(numRolls, seed, a);
int i,j;
for (i = 0; i < 6; i++) {
for (j = 0; j < 6; j++) {
cout << b[i][j];
}
cout << "\n";
}
}
