27. Write a function that will return the length of a character string. You are not allowed to use the strlen C library function. Note: Use "Pointers" concept

/* function to find string length */

# include<stdio.h>

# include<conio.h> main()

{

char str1[50]; char * c;

int len;

int lenstring(char *); clrscr();

printf("enter a string :"); scanf("%s",str1);

c = str1; len=lenstring(c);

printf("Length of the string is : %d\n",len); getch();

}

int lenstring(char *c1)

{

int count=0; while(*c1!=’\0’)

{ c1++;

count ++;

}

return count;

}
