c++ Array Problem Questions

You take a string and count the number of e.

Enter the string as scanf and save it to the array.

#define LEN 100
char line[LEN];
printf("Enter a string:");
scanf("%s", line);

If you have e, you can iterate the input array and count to +1.

short cnt = 0;
for(char  i = 0; i < LEN; i++){
    char c = line[i];
    if(c == 'e') cnt++;
}

If the count is greater than or equal to 1, output the count, and if it is 0, output bye.

if(cnt > 0) printf("%d.", cnt);
else printf("bye.");

It seems like homework, so I'm trying to ignore it, but I only add the key parts.
