Write a C program to implement the strlen() function.

The prototype of the strlen() function is...


size_t strlen(const char *string);


Here is some C code which implements the strlen() function....


int my_strlen(char *string)
{
int length;
for (length = 0; *string != '\0', string++)
{
length++;
}
return(length);
}




Also, see another example


int my_strlen(char *s)
{
char *p=s;

while(*p!='\0')
p++;

return(p-s);
}
