3. Write a user defined function which will return the length of the string declared locally in the main function.

 

#include<stdio.h>

#include<conio.h>

int length(char *);

void main()

{

    int len;

    char str[99];

    clrscr();

    printf("enter string: ");

    gets(str);

    len = length(str);

    printf("\n\nyour string length is: %d",len);

    getch();

}

int length(char *l)

{

    int i,k=0;

    for(i=0; l[i] != '\0'; i++)

    {

        k++;

    }

    return k;

}

/*  output:

enter string: vrushal pandav

your string length is: 14

*/
