-
Bint xstrlen(char s) { int length=0; while(*s!='\0') length++; s++; return (length); }
-
Cint xstrlen(char *s) { int length=0; while(*s!='\0') length++; return (length); }
-
Dint xstrlen(char *s) { int length=0; while(*s!='\0') s++; return (length); }
Answer
Correct Answer: int xstrlen(char *s) { int length=0; while(*s!='\0') { length++; s++; } return (length); }
Explanation
Option A is the correct function to find the length of given string.
Example:
#include<stdio.h>
int xstrlen(char *s)
{
int length=0;
while(*s!='\0')
{ length++; s++; }
return (length);
}
int main()

char d[] = "CuriousTab";
printf("Length = %d", xstrlen(d));
return 0;
}
Output: Length = 8
