我想知道是否可以寻求帮助。我正在用 C 编写一个程序,它写出字符串中的字符、单词和元音的数量(添加了一些打印语句)。我试图弄清楚如何编写一个循环遍历字符串并计算包含至少 3 个元音的单词的数量的代码。我觉得这是一个非常容易编写的代码,但它似乎总是让我难以理解的最简单的事情。有什么帮助吗?
另外:作为 C 的新手,如何在使用函数int vowel_count(char my_sen[])
而不是在我的 main 中使用代码时获得相同的结果?
如果这有点令人困惑,我的意思是因为我的 main 已经包含计算输入中元音数量的代码,我怎样才能将所述代码转移到这个函数中并仍然在 main 中调用它?
#include <stdio.h>
#include <string.h>
#include <ctype.h>
#define SENTENCE 256
int main(void){
char my_sen[SENTENCE], *s; //String that containts at most 256 as well as a pointer
int words = 1, count = 0,vowel_word = 0; //Integer variables being defined
int i,vowel = 0, length; //More definitions
printf("Enter a sentence: ");//Input sentence
gets(my_sen);//Receives and processes input
length = strlen(my_sen); //Stores the length of the input within length
for(i=0;my_sen[i] != '\0'; i++){
if(my_sen[i]=='a' || my_sen[i]=='e' || my_sen[i]=='i' || my_sen[i]=='o' || my_sen[i]=='u' || //Loop that states if the input contains any of the following
my_sen[i]=='A' || my_sen[i]=='E' || my_sen[i]=='I' || my_sen[i]=='O' || my_sen[i]=='U') //characters(in this case, vowels), then it shall be
{ //stored to be later printed
vowel++;
}
if(my_sen[i]==' ' || my_sen[i]=='!' || my_sen[i]=='.' || my_sen[i]==',' || my_sen[i]==';' || //Similar to the vowel loop, but this time
my_sen[i]=='?') //if the following characters are scanned within the input
{ //then the length of the characters within the input is
length--; //subtracted
}
}
for(s = my_sen; *s != '\0'; s++){ //Loop that stores the number of words typed after
if(*s == ' '){ //each following space
count++;
}
}
printf("The sentence entered is %u characters long.\n", length); //Simply prints the number of characters within the input
printf("Number of words in the sentence: %d\n", count + 1); // Adding 1 to t[he count to keep track of the last word
printf("Average length of a word in the input: %d\n", length/count);//Prints the average length of words in the input
printf("Total Number of Vowels: %d\n", vowel);//Prints the number of vowels in the input
printf("Average number of vowels: %d\n", vowel/count);//Prints the average number of vowels within the input
printf("Number of words that contain at least 3 vowels: %d\n", vowel_word);//Prints number of words that contain at least 3 vowels
return 0;
}
