C Program to Find Length of String Using Library Function

#include<stdio.h>
#include<conio.h>
#include<string.h>
void main()
{
char str[100];
int len;

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

len = strlen(str);

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

Explanation of Program :

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

len = strlen(str);

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

#include<string.h>

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