Write a function that converts a string into an int. Assume the int is between 10 and 99. Do not use the atoi() or the stoi() fu

Liula [17]

Answer:

Written in C++

#include <iostream>

#include <sstream>

using namespace std;

int main() {

string num;

cout<<"Enter a number: ";

cin>>num;

stringstream sstream(num);

int convertnum = 0;

sstream >> convertnum;

cout << "Output: " << convertnum;

}

Explanation:

Without using atoi() or stoi(), we can make use of a string stream and this is explained as follows:

This line declares a string variable num

string num;

This line prompts user for input

cout<<"Enter a number: ";

This line gets user input

cin>>num;

This line declares a string stream variable, sstream

stringstream sstream(num);

This line declares and initializes the output variable, convertnum to 0

int convertnum = 0;

The stream is passed into the output variable, convertnum

sstream >> convertnum;

This line displays the output

cout << "Output: " << convertnum;

Note that: if user enters a non integer character such as (alphabet, etc), only the integer part will be convert.

For instance,

40a will be outputted as 40

Basically, if for every row, the absolute value of the entry along the main diagonal is larger than the sum of the absolute valu

Elza [17]

Answer:

Check the explanation

Explanation:

MATLAB code:

%----------------------

function result = dominant(A)

% matrix dimensions

d = size(A);

% for loop over rows

for i = 1:d

% sum of row elements except diagonal element

sum_row =0;

% for loop over columns

for j = 1:d

% adding each elements to sum variable

sum_row = sum_row+ abs(A(i,j));

end

%subratcting diagonal element

sum_row = sum_row-abs(A(i,i));

%checking dominant condition

% failed once means matrix is not diagonal dominant

if abs(A(i,i))< sum_row

result = 'false';

return;

end

% dominant condition not failed

result = 'true';

end

% matrix A

A = [ 3 -2 1; 1 -3 2; 1 2 6]

% result

result = dominant(A)

% matrix A

A = [ -2 1 2; 1 3 2; 1 -2 0]

% result

result = dominant(A)
