Explanation:
In the first result, e is in s2 so it stops counting after h.
In the second result, a is in s2.
In the third result, none of the characters of s1 are in s2 so all charac-
ters are counted.
Gets an internal error message.
<string.h>
char *strerror(int errcode);
errcode
Returns a pointer to an internal error message string corresponding to
the specified error code errcode.
The array pointed to by strerror may be overwritten by a subse-
quent call to this function.
#include <stdio.h>
#include <string.h> /* for strerror
#include <errno.h>
int main(void)
{
}
Output:
Cannot open samp.fil: file open error
Finds the length of a string.
<string.h>
size_t strlen(const char *s);
s
Returns the length of a string.
This function determines the length of the string, not including the ter-
minating null character.
FILE *myfile;
if ((myfile = fopen("samp.fil", "r+")) == NULL)
else
fclose(myfile);
printf("Cannot open samp.fil: %s\n",
printf("Success opening samp.fil\n");
