simple Arduino code split string

Who can code in Arduino to split a string into multiple arrays and after that loop through array and split in N (nummer) and P (character) input string= 100g,40b,100g,1400f,100g,2200c,100g,1400e,100g,400i, output should be array(0)=100g array(1)=40b array(2)=40b etc after that I want to loop through arrays and split that value in n=number in the array value and p=character from the array value So the result will be N=100 and p=g N=40 and p=b I need to value P to choose which stepper motor needs to move to which position (N value)
