如何使用循环扫描字符串然后将这些字存储在数组中？

Posted 2023-02-03

#include <stdio.h>
#include <string.h>
#include <ctype.h>
#include <stdlib.h>

int main () 

 char word[100][21] ;

puts( "Enter Your Words" );

puts( "Enter STOP To Get Your Results" );

   while( strcmp( word, "STOP" ) ) 

   
    scanf( "%20s", word );

   

return 0;

在我扫描一个单词id之后将其存储到一个名为storing[][]的数组中，但我不知道如何实现它，而且我也不想存储终止的STOP字

答案

编码你想要的。

#include <stdio.h>
#include <string.h>
#include <ctype.h>
#include <stdlib.h>

#define WORD_MAX 100

int main (void)

    char storing[WORD_MAX][21]; /* you want the words stored into storing[][], not word */
    char buffer[21]; /* a buffer to store the word temporaly for not to store STOP to storing */
    int wordCount = 0; /* count how many words are stored */

    puts( "Enter Your Words" );

    puts( "Enter STOP To Get Your Results" );

    /* loop while there is room to store new word left in the array,
     * successfully read something and what is read is not the STOP word */
    while(wordCount < WORD_MAX && scanf("%20s", buffer) == 1 && strcmp(buffer, "STOP") != 0)
    
        /* store the word read and increment the count */
        strcpy(storing[wordCount++], buffer);
    

    /* sample code for testing: print what is read */
    
        int i;
        for (i = 0; i < wordCount; i++) printf("%03d : %s\n", i, storing[i]);
    

    return 0;
