الحل بلغة C

#include <stdio.h>
#include <string.h>
#include <stdbool.h>
#define MAX_SIZE 100

void printWordsOccurence(char * s) {
	
    if (s[0] == '\0')
    {
        printf("There is no text!");
    }
    
    char text[MAX_SIZE];
    char word[MAX_SIZE];
	int index;
	int beginOfNextWord = 0;
	int endOfNextWord = 0;
	int wordsCounter;
    
    // Create a copy from the original string
    for (int i = 0; i < strlen(s); i++)
    {
    	text[i] = s[i];
	}
	text[strlen(s)] = '\0';
	
	// walk through all charaters in the string
    for (int i = 0; i < strlen(text); i++)
    {
    	if (text[i] != ' ')
		{
			wordsCounter = 1;
			
			// store first occurence of the word, then remove it
			index = 0;
			int j = i;
    		for (; text[j] != ' ' && text[j] != '\0'; j++)
    		{
    			word[index] = text[j];
    			index++;
    			text[j] = ' ';
			}
			
			// remove the reset of copy of the same word
			for (; j < strlen(text); j++)
    		{
    			bool shouldClear = true;
    			
				for (int k = 0; k < strlen(word) && shouldClear == true; k++)
    			{
    				if (word[k] != text[j+k])
    				{
    					shouldClear = false;
					}
				}
				
				if (shouldClear)
				{
					for (int k = 0; k < strlen(word); k++)
    				{
						text[j+k] = ' ';
					}
    				wordsCounter++;
				}
			}
			
			word[index] = '\0';
			printf("[%d] %s\n", wordsCounter, word);
		}
	}
        
}


void main() {
    
    char * text = "I am happy. I am a doctor. I like chocolate.";
	
	printWordsOccurence(text);
	
}
		

سنحصل على النتيجة التالية عند التشغيل.

[3] I
[2] am
[1] happy.
[1] a
[1] doctor.
[1] like
[1] chocolate.
