Q. C Program to find length of a given string.

Here you will find an algorithm and program in C programming language to find length of given string. First let us understand string in C.

Explanation : The string is defined as an array of characters. The difference between a character array and a string is the string ends with a special character '\0'.

For Example : If the string is "hello", then the output will be 5.

Algorithm to find length of string

Step 1:Length = 0
Step 2: Repeat step 3 while S1 [Length] ≠ '\0'
Step 3: Length = Length + 1
Step 4: Return Length

C Program to Find the Length of a String

#include <stdio.h>
#include <string.h>
int main()
char a[100]="Letsfindcourse";
int length;
for (int i = 0; a[i] != '\0'; i++)
lenght += 1;
printf("Length of the string = %d\n", length);
return 0;


Length of the string = 14
