/* STRING LENGTH - STRLEN*/
 
#include<stdio.h>

int main()

 char str[100];

 printf("Please enter a string: ");

 // gets(str); 
 // fgets is a better option over gets to read multiword string .

 fgets(str, 100, stdin);

 // Following can be added for extra precaution for '\n' character
 // if(str[length(str)-1] == '\n') str[strlen(str)-1]=NULL;

    printf("Length of string is: %d",--i);

    1. No need to decrement the i, because it starts at 0.
