how to print a 2d array in java
for (int row = 0; row < arr.length; row++)//Cycles through rows
{
for (int col = 0; col < arr[row].length; col++)//Cycles through columns
{
System.out.printf("%5d", arr[row][col]); //change the %5d to however much space you want
}
System.out.println(); //Makes a new row
}
//This allows you to print the array as matrixprint 2d array in java
int[][] array = new int[rows][columns];
System.out.println(Arrays.deepToString(array));print 2d array in c
// most of the time I forget that there should be matrix[i][j], not matrix[i]
#include <stdio.h>
// Abdullah Miraz
int main(){
int i, j;
int matrix[2][3] = {{2,3,4,5}, {7,8,9,1}};
for(i=0;i< 2 ; i++){
for(j=0;j<3;j++){
printf("%d ", matrix[i][j]);
}
}
}print 2d array c++
for( auto &row : arr) {
for(auto col : row)
cout << col << " ";
cout<<endl;
}C print 2D array
#include <stdio.h>
#define MAX 10
int main()
{
char grid[MAX][MAX];
int i,j,row,col;
printf("Please enter your grid size: ");
scanf("%d %d", &row, &col);
for (i = 0; i < row; i++) {
for (j = 0; j < col; j++) {
grid[i][j] = '.';
printf("%c ", grid[i][j]);
}
printf("\n");
}
return 0;
