# 第七章第三题（计算数字的出现次数）(Count occurrence of numbers) – 编程练习题答案

Write a program that reads the integers between 1and 100 and counts the occurrences of each. Assume the input ends with 0.Note that if a number occurs more than one time, the plural word “times” is used

in the output.

``````Enter the integers between 1 and 100: 2 5 6 5 4 3 23 43 2 0
2 occurs 2 times
3 occurs 1 time
4 occurs 1 time
5 occurs 2 times
6 occurs 1 time
23 occurs 1 time
43 occurs 1 time``````
