C Program to find All Occurrence of a Character in a String using for loop

/* C Program to find All Occurrence of a Character in a String */
 
#include <stdio.h>
#include <string.h>
 
int main()
{
  	char str[100], ch;
  	int i, count = 0;
 
  	printf("\n Please Enter any String :  ");
  	gets(str);
  	
  	printf("\n Please Enter the Character that you want to Search for :  ");
  	scanf("%c", &ch);
  	
  	for(i = 0; i <= strlen(str); i++)
  	{
  		if(str[i] == ch)  
		{
  			printf("\n '%c' is Found at Position %d ", ch, i + 1);
  			count++;
 		}
	}
	printf("\n character '%c' occurs %d times \n ",ch,count);
  	return 0;
}

The output of the above c program; as follows:

Please Enter any String :  hello programer
Please Enter the Character that you want to Search for :  r
'r' is Found at Position 8 
 'r' is Found at Position 11 
 'r' is Found at Position 15 
 character 'r' occurs 3 times
