i have the following sequence

a = b c d b c d e c c d b c b e e

i want to create a for loop to identify the number of b’s and c’s in the sequence?

help please

No loops needed:

a = 'b c d b c d e c c d b c b e e'
no_of_bs=sum(ismember(a,'b'))
no_of_cs=sum(ismember(a,'c'))

Thanks Guillaume , what was I thinking , you are absolutely right!

thanks for this, but ive just realised that I need a for loop because I am then going to use the loop to count a different character in the sequence.

i understand that i dont necessarily need one, but is there a way to create a for loop that loops through a and counts the numebr of b’s?

thanks so much
