There can be many different ways to find the length of the string. Some of the popular methods are listed below:
The idea is to initializes a variable lengthto zero. Then iterates through the string character by character, checking each character until it encounters the null terminator (‘\0’), which signifies the end of the string. For each character encountered, increments the length counter. Once the loop completes then returns the length which will give th...
We can find the length of the string using the strlen() function. It is defined inside the strlib.h library.
We can use pointer subtraction technique to find the length of string. When we subtract the address of the first character from the address of the null terminator, the result tells us how many characters are in between, which equals the string’s length. Each character occupies one byte, so the difference directly represents the number of characters...

Calculate Length of String without Using strlen () Function. #include <stdio.h> int main () { char s [] = "Programming is fun"; int i; for (i = 0; s [i] != '\0'; ++i); printf ("Length of the string: %d", i); return 0; } Output. Length of the string: 18. Here, using a for loop, we have iterated over characters of the string from i = 0 to until ...
strcpy () strlen () C strlen () The strlen () function takes a string as an argument and returns its length. The returned value is of type size_t (an unsigned integer type). It is defined in the <string.h> header file.
Oct 9, 2023 · Approach 1: Iterative (using Loop) The most traditional method of finding the length of the string is by traversing each character through the loop. Using a counter, traverse each character of the string with the help of Loop. Update the counter for every character. When the string is terminated or a null character is identified, break the loop.
C library function - strlen () The C library strlen () function is used to calculates the length of the string. This function doesn't count the null character '\0'. In this function, we pass the pointer to the first character of the string whose length we want to determine and as a result it returns the length of the string.
