Question

for(i=0;i<=count;i++) plz explain what this instruction will do

Answer 1

Your for instructions are setting the initial value of 'i' to 0, then it is testing if 'i' is less than or equal to 'count', if it isn't, it will execute the code within the loop and then increment 'i' by one and repeat the process. This will continue until it is no longer less than or equal to count.
