Simple C Program: Input a list of numbers. Trying to output the number of occurrences in three categories. 1) >= 70; 2) 50-69 ; 3) < 50

I simply need a count for each one, so say I had the input 45 60 83 92 93 0 the output would be:

>=70 = 3

50-69= 1

< 50 = 1

Note Input ends with 0 and is not counted as an input integer
