Counting garlic -- String Length and String Length

Counting garlic -- String Length and String Length

Time Limit: 1000 ms memory limit: 65536 KB
On the right side, we provide a basically completed program, read a string, call a function called str_len to calculate the length of the string, and output it.

You should have discovered that the str_len function is not complete. Complete the str_len function without modifying the function prototype to implement the above functions.

Sample Input

Sample output

1 # include <stdio. h> 
2 # include <stdlib. h> 
3 int str_len (char * str); 
4 int main () {
5 char * str = (char *) malloc (100 * sizeof (char )); 
6 scanf ("% s", str); 
7 printf ("% d", str_len (str); 
8 free (str); 
9 return 0; 
10} 
11 int str_len (char * str) {
12 // complete your function 
13 int count = 0, I = 0 here; 
14 while (* (str + I )! = '\ 0') 
15 {
16 count ++; 
17 I ++; 
18} 
19 return count; 
20}
