Finding the Length of a String
Implementation for finding the length of a string without library functions.
- Take character array / pointer as input
- Iterate through the array until null terminator (\0) is not encountered.
- Increment length in each iteration.
- Return length
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;
}
