Answer:
1GL: Machine language. Represented by a series of 1s and 0s.
2GL: Assembly language. An assembler converts 2GL into machine language.
3GL: High-level programming language. Uses a compiler to convert into machine language.
4GL: Specifically designed for creating database management programs.
5GL: Extremely advanced. Uses statements (scripts) rather than algorithms.
Explanation:
Programming languages started as a series of binary digits (i.e. 0's and 1'). This generation of language is referred to as the first generation.
However, the machine language were difficult to read by human, so mnemonics were created (i.e. assembly language). This language uses symbolic codes such as ADD for addition, etc. This is the second generation
The third generation are the high level languages that uses languages that can be easily understood by human, e.g. + means plus. However, the language must be translated; hence the need for a compiler or interpreter, as the case may be.
The fourth and fifth generations are extensions of the third generation languages. The fourth were created to connect to DBMS while the fifth are more advanced.
Answer:
#include <stdio.h>
int main() {
const float square_feet;
printf("Enter area in square feets: ");
// reads and stores input area
scanf("%f", &square_feet);
float acres= square_feet/43560;
// displays area in acres
printf("area in acres is: %.2f", acres);
return 0;
}
Explanation:
code is in C language.
double slashed '//' lines are not code but just comments to understand what it mean in code or for explanation purpose
Answer:See the suggestions on the Opportunities tab
Explanation: The improvement in the Google ad can be made by the taking a look at the Opportunities tab which will display the adequate opportunities.
The tab displays these opportunities on the basis of the campaign settings, account's history, performance, style, trends etc and thus will create the appropriate opportunities accordingly.Thus Marcos will have to see the suggestion displayed on Opportunities tab
Answer: Plastic, metal, rubber, wiring, electricity, technology, wifi,
Explanation: You need PLASTIC to make a frame for the computer. METAL
to make an exoskeleton under the plastic frame. RUBBER to hold those loose wires and to make sure the electricity doesn't escape and shock you. ELECTRICITY to charge and make the computer runs. Technology is used for you to log in and out of your computer and WIFI to make sure it doesn't lag.
Objective reporting is reporting that separates facts and opinion.
