Answer:
c. double triple(float n) { return (3 * n); }
Explanation:
In option a print is used to print integer.While printf is used in C to print something.
In option b there is no * operator between s s s it should be s*s*s.So it will give error.
In option d there is also no multiply operator * in between 3.14 2 r it should be 3.14*2*r.
So we can say that option c is error free.

Encryption
Explanation:
Encryption is a term in the field of computer security (Cryptology) this is a process of encoding information in a way that hackers and eavesdroppers cannot read. The process of encryption involves a plain text (message) been converted into a scrambled text (cipher text) with an encryption algorithm (key) in this way, if the message is intercepted by a hacker he/she is unable to read the contents.

Answer:
See explaination
Explanation:
#include <iostream>
using namespace std;
int main()
{
double h, w;
int s, a, b;
cout<<"height in feet: ";
cin>>h;
cout<<"width in feet: " ;
cin>>w;
cout<<"tile size in inches:";
cin>>s;
int height = h*12;
if(height%s==0)
a = height/s;
else
a = height/s + 1;
int width = w*12;
if(width%s==0)
b = width/s;
else
b = width/s + 1;
cout<<"Number of tiles: "<<a*b;
}
