Wireless Signals, Radio & Network Protocols Explained
Antennas and Electromagnetic Waves
In many communication systems, it’s not necessary for the sender and receiver to be connected by a physical cable. This wireless communication is achieved using an antenna. Antennas are devices responsible for converting electromagnetic waves into electrical impulses (reception) and vice versa (transmission).
An electrical conductor, such as an antenna, can emit energy as electromagnetic waves if a variable electric current flows through it. These electromagnetic

Write a program with a function that takes an array as an argument and returns its sum to the main function.
(Note: The following code demonstrates passing array elements to a function, not summing an array as per the heading’s question.)
#include <stdio.h>
void display(int age1, int age2) {
printf("%d\n", age1);
printf("%d\n", age2);
}
int main() {
int ageArray[] = {2, 8, 4, 12};
// pass second and third elements to display()
display(ageArray[1], ageArray[2]);
return 0;
