Lesson 11 Array Part 2

Example 1 Printing two dimensional array

#include<stdio.h>
#include<conio.h>
int i, j;
int row = 3;
int col = 3;
int main() {	
	int a[3][3] = { {1,2,3}, {4,5,6}, {7,8,9}};

	for (i = 0; i < row; i++) {
		for (j = 0; j < col; j++)
		{
			printf_s("%3d", a[i][j]);
		}
		printf_s("\n");
	}
	_getch();
	return 0;
}

Example 2

#include<stdio.h>
#include<conio.h>
int main() {
	int i, j;
	int a[3][2] = { { 1, 4 }, 
			{ 5, 2 },
			{ 6, 5 } };

	for (i = 0; i < 3; i++) { 
		for (j = 0; j < 2; j++) { 
			printf("%d ", a[i][j]);
		}
		printf("\n");
	}
	_getch();
	return 0;
}

Example 3

#include<stdio.h>
#include<conio.h>
int main() {
	int i, j;
	int a[3][2] = { { 1 },
				  { 5, 2 },
				  { 6 } };

	for (i = 0; i < 3; i++) {
		for (j = 0; j < 2; j++) {
			printf("%d ", a[i][j]);
		}
		printf("\n");
	}
	_getch();
	return 0;
}

Example 4 Accessing Array

#include<stdio.h>
#include<conio.h>
int main() {
	int arr[] = {10,11,12,13,14,15 };
	int i;
	for (i = 0; i <= 5; i++) {
		printf("\n%d %d %d %d %d", arr,arr[i], *(i + arr), 
									*(arr + i), i[arr]);
	}
	_getch();
	return 0;
}
