第一步：

建立数组，并打印出不同长度的单词数目：

#include<stdio.h>main(){int c, i;int length = 0;int pitLock = 1;int charLen[10];for (int i = 0; i < 10; i++)charLen[i] = 0;while ((c = getchar()) != EOF){if ((c >= 'a') && (c <= 'z') && (pitLock == 1)){length++;}else if (pitLock == 1){++charLen[length - 1];length = 0;}    else pitLock = 0;}for ( i = 0; i < 10; i++){printf("length = %d: %d\n", i + 1, charLen[i]);}}

第二步：

调用函数实现星号直方图打印

#include<stdio.h>void print_star(int);main(){int c, i;int length = 0;int pitLock = 1;int charLen[10];for (int i = 0; i < 10; i++)charLen[i] = 0;while ((c = getchar()) != EOF){if ((c >= 'a') && (c <= 'z') && (pitLock == 1)){length++;}else if (pitLock == 1){++charLen[length - 1];length = 0;}    else pitLock = 0;}for ( i = 0; i < 10; i++){printf("length = %2d: %4d |", i + 1, charLen[i]);print_star(charLen[i]);}return 0;}void print_star(int num){while (num) {printf("*");--num;}printf("\n");}
