Finding String Length
Learn how to calculate the length of the string in this lesson.
We'll cover the following
To help programmers work with strings effectively, C library provides several functions, like strlen( )
, strcpy( )
, strcat( )
, strcmp( )
, etc. Without these library functions, we would need to develop parallel functions ourselves.
The strlen()
function
strlen( )
returns the length of the string, i.e., the number of characters present in the string, excluding the null terminating character.
The basic syntax of the strlen()
function is given below:
int strlen(const char *stringName);
Here, stringName
points to the string whose length is to be found.
