nested for loops code example

Example 1: nested for loops javascript

// Basic Javascript Nested Loop / 2D Array

for (var x = 0; x < 10; x++) {
	for (var y = 0; y < 10; y++) {
    	console.log("x: " + x + ", y: " + y);
    }
}

Example 2: nested for loop in java

// outer loop
for (int i = 1; i <= 5; ++i) {
  // codes

  // inner loop
  for(int j = 1; j <=2; ++j) {
    // codes
  }
..
}

Example 3: nested loop

#include<stdio.h>

int main()
{
    int sum = 0, i, j;

    for(i = 0; i < 3; i++)
    {
        sum += i;
        for(j = 0; j < 3; j++)
        {
            sum += j;
            if(((i + j) % 2) == 1)
                break;
        }
    }

    printf("%d",sum);

    return 0;
}

Example 4: nested loop

int inner;
 string result = " "; 
 for (int outer = 0; outer < 3; outer++)
            {
                for (inner = 10; inner > 5; inner--)
                {
                    result += string.Format("Outer: {0} \tInner: {1} \n\n", outer,
                               inner);
                }
            } MessageBox.Show(result);
        }

Example 5: arrays with for loops

Account[] accounts;

// 1. allocate the array (initially all the pointers are null)
accounts = new Account[100];	

// 2. allocate 100 Account objects, and store their pointers in the array
for (int i=0; i<accounts.length; i++) {
  accounts[i] = new Account();
}

// 3. call a method on one of the accounts in the array
account[0].deposit(100);
