Count Occurrences of a Word in a Sentence

C Program: Count Occurrences of a Word in a Sentence

C 
#include <stdio.h>


#include <string.h>


 


int main() {


    char str[200], word[50];


    char temp[200];


    int count = 0;


 


    printf("Enter a sentence: ");


    fgets(str, sizeof(str), stdin);


    str[strcspn(str, "\n")] = '\0'; // remove newline


 


    printf("Enter the word to find: ");


    scanf("%s", word);


 


    // Copy sentence to temp so strtok() won't modify the original string


    strcpy(temp, str);


 


    char *token = strtok(temp, " ");


    while (token != NULL) {


        if (strcmp(token, word) == 0) {


            count++;


        }


        token = strtok(NULL, " ");


    }


 


    printf("\nThe word '%s' occurs %d time(s) in the sentence.\n", word, count);


 


    return 0;


}

Output

 
OUTPUT :
Enter a sentence: This is a test and this is simple
Enter the word to find: is

The word 'is' occurs 2 time(s) in the sentence.

Explanation

  • Reads a sentence using fgets() and a target word using scanf().
  • Uses strtok() to split the sentence into words (separated by spaces).
  • Compares each word with the target word using strcmp().
  • Counts how many times the word appears.
