Answer:

True

Explanation:

A computer can be defined as an electronic device that is capable of receiving of data in its raw form as input and processes these data into information that could be used by an end user.

Generally, a computer is composed of five (5) main components and these include;

I. Input unit.

II. Output unit.

III. Central processing unit (CPU).

IV. Storage (memory) unit.

V. Power supply unit (PSU).

A power supply also referred to as power supply unit (PSU) can be defined as a hardware component of a computer that converts and step-down the domestic alternating current (AC) electrical power to a low-voltage regulated direct current (DC) power, so that the internal components of a computer can be supplied with power.

Hence, the power supply unit (PSU) serves as a rectifier by converting alternating current (AC) house current to direct current (DC) and as a transformer to step-down voltage from 220 Volts or 110 Volts to 50, 30, or 20 Volts depending on the requirements of a computer.

cin>>name; //input value

cout<<"Enter scores in following scoring items between 0 and 100:"<<"\n";//print message

cout<<"Enter class participation score: ";//print message

cin>>clspat;//input value

cout<<"Enter assignment score: ";//print message

cin>>asst;//input value

cout<<"Enter exam score: ";//print message

cin>>exam;//input value

cout<<"Enter practice score: ";//print message

cin>>practice;//input value

total=clspat+test+asst+exam+practice;//calculating total value

average=total/5;//calculating average value

cout<<endl<<"SCORE CARD OF "<<name<<"\n"<<"-----------------------"<<"\n";//print value with message

cout<<"Total score: "<<total<<"\n";//print message with value

cout<<"Average score: "<<average; //print message with value

}

Output:

please find the attached file.

Explanation:

In this code, the floating-point variable is declared, which is used for input value from the user-end and after input the floating-point value it uses the "total, average" variable to calculate its respective values and store its value with init, after storing the value into the variable it uses the print method to print its values.

Write a loop to store the letters “f” through “w” in an array named letters. Then, print the contents of the array to the screen
Luda [366]

Answer:

#include<iostream>

#include<conio.h>

using namespace std;

main()

{

 

char a[18];

 

int k=102;

for (int j=0; j<18; j++)

{

a[j]=k;  

k=k+1;

 

}

 

cout<<"The Array of characters between f and W is Given below"<<endl;

for (int l=0;l<18;l++)

{

 cout<<a[l]<<endl;

}

getch();  

}

Explanation:

In this program, list of characters has been printed between f and w using for loop as per requirement. An array has been taken with name a and size 18, as there are 18 elements from f to w. As we know that ASCII code of Small f is 102 in decimal, we store that in another variable k. Start loop  and assign ASCII code of each alphabet using 'k' variable to array a. After that array of assigned alphabets has been printed.
