Before starting with this tutorial we assume that you are best aware of the following C programming topics:

Operators in C Programming.
Basic Input and Output function in C Programming.
Basic C programming.

Concepts of for loop.
Using String functions of c language.

Find the Length of a String.

As we all know the String is a collection of character data types. In strings, only one variable is declared which can store multiple values. First will take the string from the user. Then will pass that string to a for loop for copying. The C programming language has many pre-defined functions for string manipulation. but in today’s tutorial, we will do it with the help of for loop.

With the help of this program, we can Find the Length of a String.

Algorithm:-

1. Declaring the variables required for the program.

2. Taking input string from the user.

3. Storing the input from the user.

4. Using for loop to find the length of input string.

5. rinting the length of the string

6. End

1. Declaring the variables required for the program.

2. Taking input string from the user.

3. Storing the input from the user.

4. Using for loop to find the length of input string.

5. rinting the length of the string

6. End

Program to Find the Length of a String:-

#include <stdio.h>
#include <string.h>
// C program to find the length of string
int main()
{
    //Declaring the variables required for the program
	char String[1000];
	int i;
	
    //Taking input string from the user 
	printf("Enter the String: ");
	
	//Storing the input from the user 
	scanf("%s", String);
	
    //using for loop to find the length of given string
	for (i = 0; String[i] != '\0'; ++i);
	
    //Printing the length of the string
	printf("Length of String is %d", i);

	return 0;
}

#include <stdio.h>

#include <string.h>

// C program to find the length of string

int main()

{

//Declaring the variables required for the program

char String[1000];

int i;

//Taking input string from the user

printf("Enter the String: ");

//Storing the input from the user

scanf("%s", String);

//using for loop to find the length of given string

for (i = 0; String[i] != '\0'; ++i);

//Printing the length of the string

printf("Length of String is %d", i);

return 0;

}

Output:-

In the above program, we have first initialized the required variable.

string1[100] = it will hold the string value.
string2[100] = it will hold the string value.

i = it will hold the integer value for the loop.

Taking input string from the user.

Reading the input string from the user/Storing the input from the user.

Find the length using for loop of a given string.

Printing the length of the string
