3. int xstrlen(char *s) { int length=0; while(*s!='\0') length++; return (length); }

4. int xstrlen(char *s) { int length=0; while(*s!='\0') s++; return (length); }

Which of the following function is correct that finds the length of a string?1. int xstrlen(char *s) { int length=0; while(*s!='\0') { length++; s++; } return (length); }

Part-2Tell Yes or No

Will the program compile successfully?

#include<stdio.h>int main(){ char a[] = "India"; char *p = "BIX"; a = "BIX"; p = "India"; printf("%s %s\n", a, p); return 0;}

Yes or No

For the following statements will arr[3] and ptr[3] fetch the same character?char arr[] = "IndiaBIX";

Yes or No

Is there any difference between the two statements?char *ch = "IndiaBIX";

&char ch[] = "IndiaBIX";

Yes or No

Is there any difference between the two statements?char *ch = "IndiaBIX";

&char ch[] = "IndiaBIX";

Yes or No

Part-3Find Out the Output
