9.3 Length of String

The following is a sample program to obtain the length of the inputed string. Note that number

of bytes and number of characters are not distinguished.

/* length.c

*

* a sample program to obtain the length of the inputed string

* NOT INTERNATIONALIZED

*/

#include 

#include 

int main(int argc, char **argv)

{

int len;

if (argc < 2) {

printf("Usage: %s [string]\n", argv[0]);

return 0;

}

printf("Your string is: \"%s\".\n", argv[1]);

len = strlen(argv[1]);

printf("Length of your string is: %d bytes.\n", len);

printf("Length of your string is: %d characters.\n", len);

printf("Width of your string is: %d columns.\n", len);

return 0;

}

The following is a internationalized version of the program using wide characters.
