for (int j=0;j<800;j+100){

Error : not a statement

Answer 1

You have to use j+=100 `to incremental your index with 100 :

for (int j=0; j<800; j+=100){
   //body
}

Edit

any other methods to express +100

Here is another way:

for (int j = 0; j < 800; ) {
//----------------------^no parameter here
    //body
    j += 100;//this equivalent to j = j + 100;
}
