Answer:
Both high and low level computer languages are used to communicate directly with a computer, so the answer is D.
Explanation:
Answer:
The old cathode Ray tube technology was replaced by the less bulkier and more modern liquid crystal display and LED technology.
Explanation:
The old cathode ray tube uses the principle of electrical discharge in gas. Electrons moving through the gas, and deflected by magnetic fields, strike the screen, producing images and a small amount of X-rays. The tube required more space, and consumed more electricity, and was very bulky. The modern technologies are more compact and consume less power, and can been designed to be sleek and less bulky.
The program is an illustration of loops.
Loops are used to perform repetitive and iterative operations.
The program in C++ where comments are used to explain each line is as follows:
#include <iostream>
using namespace std;
int main(){
//This declares and initializes all variables
string star = "*", blank = " ", temp;
//The following iteration is repeated 8 times
for (int i = 1; i <= 8; i++) {
//The following iteration is repeated 8 times
for (int j = 1; j <= 8; j++) {
//This prints stars
if (j % 2 != 0) {
cout << star;
}
//This prints blanks
else if (j % 2 == 0) {
cout << blank;
}
}
//This swaps the stars and the blanks
temp = star;
star = blank;
blank = temp;
//This prints a new line
cout << endl;
}
}
