passing 2d array to function in c++ code example
Example 1: Passing a matrix in a function C
void ins (size_t rows, size_t columns, int matrix[rows][columns]);
Example 2: passing 2d array as parameter to function in c
#include <stdio.h>
void fun(int *arr, int m, int n)
{
int i, j;
for (i = 0; i < m; i++){
for (j = 0; j < n; j++)
printf("%d ", *((arr+i*n) + j));
printf("\n");
}
}
int main(void)
{
int arr[][4] = {{1, 2, 3,4}, {4, 5, 6,7}, {7, 8, 9,0}};
int m = 3, n = 4;
fun(&arr, m, n);
return 0;
}
Example 3: passing a 2d array cpp
#include <iostream>
#include <vector>
using namespace std;
typedef vector< vector<int> > Matrix;
void print(Matrix& m)
{
int M=m.size();
int N=m[0].size();
for(int i=0; i<M; i++) {
for(int j=0; j<N; j++)
cout << m[i][j] << " ";
cout << endl;
}
cout << endl;
}
int main()
{
Matrix m = { {1,2,3,4},
{5,6,7,8},
{9,1,2,3} };
print(m);
Matrix n( 3,vector<int>(4,0));
print(n);
return 0;
}
