Write a program that reverses the words in a sentence.

Enter a sentence: you can cage a swallow can't you?
Reversal of sentence: you can't swallow a cage can you?

Hint: Use a loop to read the characters one by one and store them in a one-dimensional char array. Have the loop stop at a period,question mark,or exclamation point (the “terminating character “),which is saved in a separate char variable. Then use a second loop to search backward through the array for the beginning of the last word. Print the last word,then search backward for the next-to-last word. Repeat until the beginning of the array is reached. Finally,print the terminating character.

我一直在考虑将一个单词定义为空格之间的一系列字符.因此,当到达空间时,向后移动,打印每个字符,直到找到另一个空格.我的第一个版本的程序只打印了第一个单词.它的当前版本只打印其他单词.我已经坚持了两天,所以任何帮助都真的很感激.这是我的代码,以及输出示例.希望我已正确记录我的代码.提前致谢！

码

/* Include the standard I/O library */
#include<stdio.h>

/* Define main */
int main(void) {

    /**
     * Declare an array of characters storing the sentence,as well as
     * a character representing the current character under cursor and
     * the terminating character
     */
    char sentence[100] = { ' ' },c,tc;

    /**
     * Declare a loop counter already initialized at 0,an incremental
     * variable,as well as the size of the read sentence
     */
    int i = 0,j = 1,size = 0;

    /* Get the sentence */
    printf("Enter a sentence: \n");
    for(c = getchar(); (c != '.') && (c != '!') && 
        (c != '?') && (c != '\n'); c = getchar(),i++) {

        sentence[i] = c; /* Store the current character in the array */
        size++; /* Increase the sentence's size */
    }

    tc = c; /* Get the terminating character */

    /**
     * Go backward through the array,printing each sequence of characters
     * between spaces
     */
    for(i = 99; i >= 0; i--) {

        if(sentence[i] == ' ') {

            while(sentence[i + j] != ' ') {

                printf("%c",sentence[i + j]);
                j++;
            }

            j = 1; /* Reset the incremental variable */
            printf(" "); /* Print a tailing space */
        }
    }

    /**
     * Delete the tailing blank space and print the terminating character,* as well as a new line 
     */
    printf("\b%c\n",tc);

    return 0; /* Return 0 upon successful program execution */
}
