Answer:

Zero(0)

Explanation:

<u>Global Variables </u>

Variables which are declared outside any function. Any function can use these variables,they are automatically initialized to zero(0).They are generally declared before main() function.

Example- C program for showing global variable is 0.

#include <stdio.h>

int g; // declaring g as global variable

int main()

{

printf("%d",g); //printing global variable

return 0;

}

<u>Output</u>

When a single controller device communicates with multiple peripheral devices, what wires are simultaneously connected to all de

Tems11 [23]

The wires that are simultaneously connected to all devices in the network are;

SDA(Serial data line) and SCL

Integrated Circuits Communication

This involves I²C which is a form of communication based on integrated circuits.

Now, this I²C is a serial communication interface that has a bidirectional two-wire synchronous serial bus which usually comprises of two wires namely SDA (Serial data line) and SCL (Serial clock line).

mixer [17]

int main()

{

string str;

cout<<"Enter the string: ";

cin>>str;

for(int i=0;str[i]!='\0';i++){

if(str[i]=='e'){

str[i]='x';

}

}

cout<<"the string is: "<<str<<endl;

return 0;

}

Explanation:

First, include the library iostream for using the input/output instructions.

Create the main function and declare the variables.

Then, use the cout instruction and print the message on the screen.

cin store the string enter by the user into a variable.

After that, take a for loop and if-else statement for checking the condition if the string contains the 'e', then change that alphabet to 'x'.

This process continues until the string not empty.

Finally, print the updated string.

let m be a positive integer with n bit binary representation an-1 an-2 ... a1a0 with an-1=1 what are the smallest and largest va

Ahat [919]

Answer:

Explanation:

From the given information:

$a_{n-1} , a_{n-2}...a_o$ in binary is:

$a_{n-1}\times 2^{n-1} + a_{n-2}}\times 2^{n-2}+ ...+a_o$

So, the largest number posses all $a_{n-1} , a_{n-2}...a_o$ nonzero, however, the smallest number has $a_{n-2} , a_{n-3}...a_o$ all zero.

∴

The largest = 11111. . .1 in n times and the smallest = 1000. . .0 in n -1 times

i.e.

$(11111111...1)_2 = ( 1 \times 2^{n-1} + 1\times 2^{n-2} + ... + 1 )_{10}$

$= \dfrac{1(2^n-1)}{2-1}$

$\mathbf{=2^n -1}$

$(1000...0)_2 = (1 \times 2^{n-1} + 0 \times 2^{n-2} + 0 \times 2^{n-3} + ... + 0)_{10}$

$\mathbf {= 2 ^{n-1}}$

Hence, the smallest value is $\mathbf{2^{n-1}}$ and the largest value is $\mathbf{2^{n}-1}$
