Can somebody help me why is this infinity loop in C?

Question

I am actually solving a beginner questions from CodeForce(compitative programming)
Question link:
https://codeforces.com/problemset/problem/510/A
But below code outputs infinity loop.

My code:

#include <stdio.h>
#include <stdlib.h>

int main()
{
int n=5,m=3;//row,column

char board[n][m];
int i,j,side=0;//side is for in which side the hash(#) will be placed on the board

int dotIndex;//dotIndex is positional value on a board where the dot(.) will be placed

for(i=0;i<n;i+2)
{

for(j=0;j<m;j++)
{
board[i][j]='#';
printf("\ni = %d j = %d",i,j);
}
printf("\nStep 2");
if(side%2==0)
{
board[i+1][m-1]='#';
for(dotIndex=0;dotIndex<m-2;dotIndex++)
board[i+1][dotIndex]='.';
}
else{
board[i+1][0]='#';
for(dotIndex=1;dotIndex<m-1;dotIndex++)
board[i+1][dotIndex]='.';
}
printf("\nStep 4");
side++;

}

//Display board
printf("\n");
for(i=0;i<n;i++)
{
for(j=0;j<m;j++)
{
printf(" %c",board[i][j]);
}
printf("\n");
}
return 0;
}

Answer 1

It is a infinet loop because of line fifteen

for(i=0;i<n;i+2)

You forgot the equal sign it should be

for(i=0;i<n;i+=2)

Answer 2

Caleb in fact, that's the equal sign wich was forgotten by OP, not the plus ;P
