design

Explanation:

Based on the information provided within the question it can be said that these are called design reviews. This is one of the most important parts of the development of a system. This focuses more on answering how something is going to be done in the system as opposed to answering what is going to be done for the system depending on the questions asked in the analysis phase.

Write a C program that reads two hexadecimal values from the keyboard and then stores the two values into two variables of type

sattari [20]

Solution :

#include $$$$

//Converts $\text{hex string}$ to binary string.

$\text{char}$ * hexadecimal $\text{To}$ Binary(char* hexdec)

{

long $\text{int i}$ = 0;

char *string = $(\text{char}^ *) \ \text{malloc}$ (sizeof(char) * 9);

while (hexdec[i]) {

//Simply assign binary string for each hex char.

switch (hexdec[i]) {

$\text{case '0'}:$

strcat(string, "0000");

break;

$\text{case '1'}:$

strcat(string, "0001");

break;

$\text{case '2'}:$

strcat(string, "0010");

break;

$\text{case '3'}:$

strcat(string, "0011");

break;

$\text{case '4'}:$

strcat(string, "0100");

break;

$\text{case '5'}:$

strcat(string, "0101");

break;

$\text{case '6'}:$

strcat(string, "0110");

break;

$\text{case '7'}:$

strcat(string, "0111");

break;

$\text{case '8'}:$

strcat(string, "1000");

break;

$\text{case '9'}:$

strcat(string, "1001");

break;

case 'A':

case 'a':

strcat(string, "1010");

break;

case 'B':

case 'b':

strcat(string, "1011");

break;

case 'C':

case 'c':

strcat(string, "1100");

break;

case 'D':

case 'd':

strcat(string, "1101");

break;

case 'E':

case 'e':

strcat(string, "1110");

break;

case 'F':

case 'f':

strcat(string, "1111");

break;

default:

printf("\nInvalid hexadecimal digit %c",

hexdec[i]);

string="-1" ;

}

i++;

}

return string;

}

int main()

{ //Take 2 strings

char *str1 =hexadecimalToBinary("FA") ;

char *str2 =hexadecimalToBinary("12") ;

//Input 2 numbers p and n.

int p,n;

scanf("%d",&p);

scanf("%d",&n);

//keep j as length of str2

int j=strlen(str2),i;

//Now replace n digits after p of str1

for(i=0;i<n;i++){

str1[p+i]=str2[j-1-i];

}

//Now, i have used c library strtol

long ans = strtol(str1, NULL, 2);

//print result.

printf("%lx",ans);

return 0;

Create the following matrix M: 1 7 13 19 25 ?-3 9 15 21 27 5 11 17 2329By writing one command and using the colon to address ran

zimovet [89]

Answer:

Matlab code is:

>> $M=reshape(1:2:29, 3,5)$

>> $\% (a)$

>> $Va=M(3,:)$

>> $\% (b)$

>> $Vb=M(:,4)$

>> $\% (c)$

>> $Vc=[M(2,:) M(:,3)']$

Explanation:

>> $\% \ Making\ the\ Matrix\ With\ required\ terms\ 1\ to\ 29\ with\ spaces\ of\ 5\ in\ three\ rows$

>> $M=reshape(1:2:29, 3,5)$

$M =$

1 7 13 19 25

3 9 15 21 27

5 11 17 23 29

>> $\% (a)$

>> $\%\ Slicing\ M\ \ from\ third\ row\ till\ end$

>> $Va=M(3,:)$

$Va =\\\ 5\ 11\ 17\ 23\ 29$

>> $\% (b)$

>> $\% \ Slicing\ the\4th\ column\ of\ M\ matrix\$

>> $Vb=M(:,4)$

$Vb =\\ 19\\ 21\\ 23\\$

>> $\% (c)$

>> $\% \ slicing\ the\ 2nd\ row\ and\ 3rd\ column\ of\ M\ Matrix\ and\ combining\ them\ to\ make\ a\ row\ matrix$

>> $Vc=[M(2,:) M(:,3)']$

$Vc =\\ 3\ 9\ 15\ 21\ 27\ 13\ 15\ 17$

The code is tested and is correct. If you put a semi colon ' ; ' at the end of every statement then your answer will be calculated but matlab doesn't show it until you ask i.e. typing the variable (Va, Vb, Vc )and press enter.
