Why is special code needed for <?

Are commonly used to control the number of times that a loop iterates?

pickupchik [31]

Hmm... I feel like this query is much broader than it should be. However, I will start my initial answer, then another potential solution.

My initial answer to your query was: A condition controlled loop is used to control the number of times a loop iterates.

The potential answer, my secondary one, is: A count controlled loop iterates a specific number of times.

Two results, but my initial answer is the solution I opted when understanding this.

Computer A has an overall CPI of 1.3 and can be run at a clock rate of 600 MHz. Computer B has a CPI of 2.5 and can be run at a

kirill115 [55]

Answer:

Check the explanation

Explanation:

CPI means Clock cycle per Instruction

given Clock rate 600 MHz then clock time is Cー 1.67nSec clockrate 600M

Execution time is given by following Formula.

Execution Time(CPU time) = CPI*Instruction Count * clock time = $\frac{CPI*Instruction Count}{ClockRate}$

a)

for system A CPU time is 1.3 * 100, 000 600 106

= 216.67 micro sec.

b)

for system B CPU time is $=\frac{2.5*100,000}{750*10^6}$

= 333.33 micro sec

c) Since the system B is slower than system A, So the system A executes the given program in less time

Hence take CPU execution time of system B as CPU time of System A.

therefore

216.67 micro = = $\frac{2.5*Instruction}{750*10^6}$

Instructions = 216.67*750/2.5

= 65001

hence 65001 instruction are needed for executing program By system B. to complete the program as fast as system A

Create a program in c/c++ which accepts user input of a decimal number in the range of 1 -100. Each binary bit of this number wi

kirill115 [55]

Answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

void switch_fun(int input)

{

//array to store binary of input number

int bin[7];

// convert the number into binary

for(int i=0; input>0; i++)

{

bin[i]=input%2;

input= input/2;

}

// print the switch number and their status

cout<<"Switch number:\t 1\t 2\t 3\t 4\t 5\t 6\t 7 \n";

cout<<"status: ";

for(int j=6;j>=0;j--)

{

// if bit is 1 print "ON" else print "OFF"

if(bin[j]==1)

cout<<"\t ON";

else

cout<<"\t OFF";

}

int main()

{

int n;

cout<<"enter the number between 1-100 only:");

// read a number in decimal

cin>>n

// validate the input

while(n<1 ||n>100)

{

cout<<"wrong input!! Input must be in between 1-100:"<<endl;

cout<<"enter the number again :";

cin>>n;

}

// call the function with input parameter

switch_fun(n);

return 0;

}

Explanation:

Read a decimal number from user. If the number is not between 1 to 100 the it will again ask user to enter the number until the input is in between 1-100.Then it will call the fun() with parameter n. First it will convert the decimal to binary array of size 7.Then print the status of switch.If bit is 1 then print "ON" else it will print "OFF".

Output:

enter the number between 1-100 only:-5

wrong input!! Input must be in between 1-100:

enter the number again :125

wrong input!! Input must be in between 1-100:

enter the number again :45

Switch number: 1 2 3 4 5 6 7

Status: OFF ON OFF ON ON OFF ON

What is the minimum number of bits you need to encode the 26 letters of the alphabet plus a space?Pace?

Andrei [34K]

Answer

5 bits

Explanation

A bit is the least or the smallest unit of data in a computer. They are the units of information in information theory, consisting of the amount of information required to specify one of two alternatives 0 and 1. This is because A bit has a single binary value, either 0 or 1

If you use roman alphabet A to Z lets use log 2(26)=4.7 bits. when you round off it will be 5 bits.
