In this article, we will write a C program to find the length of the string using Pointer.

Write a C program to find the length of the string using Pointer

#include <stdio.h>
#include <conio.h>

int string_ln(char*);

void main()
{
	char str[20];
	int length;
	clrscr();

	printf("\nEnter any string : ");
	gets(str);

	length = string_ln(str);
	printf("The length of the given string %s is : %d", str, length);
	getch();
}

int string_ln(char *p) /*p=&str[0] */
{
	int count = 0;
	while (*p != '\0')
	{
		count++;
		p++;
	}
	return count;
}

Input:

Enter the String : sourcecode

Output:

Length of the given string pritesh is : 10
