# Finding the Length of a String

### Procedure :

* Take character array / pointer as input
* Iterate through the array until null terminator (\0) is not encountered.
* Increment length in each iteration.
* Return length

```c
int findLength(char *a) {

    // Variable to track length
    int len = 0;
    
    // Iterate till null character is not found
    for (int i = 0; a[i] != '\0'; i++) {
       len++; 
    }
    
    return len;

}
```
