编写一个 C 语言程序来利用 while 循环计算句子的平均单词长度
问题
在运行时输入一个句子,编写代码来计算句子中单词的平均长度
解决方案
算法
START Step 1: declare character, int and double variables Step 2: Enter any statement Step 3: while loop Check condition stmt[i]=getchar()) != '
' True then enter into loop Increment I and call the function at step 5 Step 4: Print the average length return by function From step 5 Step 5: called function calculatewordlength i. declare and initialize charcount=0 and wordcount=1 ii. while loop check condition (*stmt != '
') if it trues enter into loop 1. if(*stmt != ' ') 2. charcount++; 3. else if(*stmt == ' ') 4. wordcount++; 5. stmt++; iii. return (double)charcount/wordcount; STOP
