In C++

Define a function int length(char s[]) that returns the length of C-String s (not including the terminating null character).

For example

length("abc") will return 3

and length("") will return 0.

Driver code below.

#include

using namespace std;

int length (char s[]) ;

int main() {

char s[80];

cin.getline(s,80);

cout << "s = \"" << s << "\"" << endl;

cout << "length = " << length(s) << endl;

return 0;

}
