Explanation / Answer

Ans a)

% Create sample data.
array = -5 : 6;
sumx2=0
k = 1;   
while k <= length(array) %While loop to access array
evens=mod(k,2)==0;
if evens==1
sumx2=sumx2+array(k);
end
k = k+1; % Increment Counter
end
sumx2

Ans b)

% Create sample data.
array = -5 : 6;
sumx2=0
k = 1;   
while k <= length(array) %While loop to access array
evens=mod(k,2)==0;
if evens==0
sumx2=sumx2+array(k);
end
k = k+1; % Increment Counter
end
sumx2

Ans c)

% Create sample data.
array = -5 : 6;
sumx2=0
k = 1;   
while k <= length(array) %While loop to access array
evens=mod(array(k),2)==0;
if evens==1
sumx2=sumx2+array(k);
end
k = k+1; % Increment Counter
end
sumx2

Ans d)

% Create sample data.
array = -5 : 6;
sumx2=0
k = 1;   
while k <= length(array) %While loop to access array
evens=(mod(array(k),2)==0&&array(k)>0);
if evens==1
sumx2=sumx2+array(k);
end
k = k+1; % Increment Counter
end
sumx2

Ans e)

% Create sample data.
array = -5 : 6;
sumx2=0
k = 1;   
while k <= length(array) %While loop to access array
evens=(mod(array(k),2)==0&&array(k)<0);
if evens==1
sumx2=sumx2+array(k);
end
k = k+1; % Increment Counter
end
sumx2

Ans f)

% Create sample data.
array = -5 : 6;
sumx2=0
k = 1;   
while k <= length(array) %While loop to access array
evens=(mod(array(k),2)==0);
if evens==0
sumx2=sumx2+array(k);
end
k = k+1; % Increment Counter
end
sumx2

Ans g)

% Create sample data.
array = -5 : 6;
sumx2=0
k = 1;   
while k <= length(array) %While loop to access array
evens=(mod(array(k),2)!=0&&array(k)>0);
if evens==1
sumx2=sumx2+array(k);
end
k = k+1; % Increment Counter
end
sumx2

Ans h)

% Create sample data.
array = -5 : 6;
sumx2=0
k = 1;   
while k <= length(array) %While loop to access array
evens=(mod(array(k),2)!=0&&array(k)<0);
if evens==1
sumx2=sumx2+array(k);
end
k = k+1; % Increment Counter
end
sumx2
