C Program to Find Length of String Using Library Function

Find Length of String Using Library Function

#include<stdio.h>
#include<string.h>

int main() {
   char str[100];
   int len;

   printf("\nEnter the String : ");
   gets(str);

   len = strlen(str);

   printf("\nLength of Given String : %d", len);
   return(0);
}

#include<stdio.h>

#include<string.h>

int main() {

char str[100];

int len;

printf("\nEnter the String : ");

gets(str);

len = strlen(str);

printf("\nLength of Given String : %d", len);

return(0);

}

Explanation of Program :

We need to find the length of the string using library function provided by C Programming.

len = strlen(str);

1	len = strlen(str);

strlen() function will evaluate the length of the string and return the string length (i.e integer value).

#include<string.h>

1	#include<string.h>

We need to include string.h header file in order to use string manipulation functions in c program.
