Do you think posting with such big fonts will make big impact?

For the first, set a variable V to zero, loop over the string, and check each character to see if it's an 'a'. If it is, then increase V by 1.

The second one is even easier; you don't have to wait until the loop ends and can bail out at the first occurrence. Therefore you don't even need V.
