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
