Question

How do I write a C program that finds how many times a word is used in a string and prints the result. The string is hardcoded. How do I also make it print the hashes?

For instance: String: " Dog Cat Owl Ferret Rabbit Cat Dolphin Penguin Cat"

Word 1: Owl

Word 2: Cat

Desired Output:

Owl- 1 time(s)

Cat: 3 time(s)

Owl- #

Cat-###

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

/* Function declaration */
int counting(char * s, char * w);

int main()
{
char str[500];
char substr[100];
int count;
/* Input string and word from user */
printf("Enter main string: ");
fgets(str,500, stdin);
  
/*do while loop to search for words continuously*/
while(1){
int k=0;
printf("Enter word to search: ");
/*scanf("%s",&substr);*/
gets(substr);
  
count = counting(str, substr);
printf("%s -",substr);
  
for(k=0;k<count;k++)
{
printf("#");
}
printf("\n");
}
  
  
return 0;
}
