Question

MATLAB

Task: Use a for loop to find how many numbers you have to add to get a sum greater than 1,000. The numbers in the problem are consecutive, so adding up 1+2+3+4+5+6+.... until you reach the user defined value 1000.

Method : must Make a variable equal to 1 then add 2, 3, 4...to it, until you reach 1000, then you break out the loop once the sum hits 1,000.

Answer 1

Following is the matlab script in which the code is implemented

MATLAB Code:

% sum is a global variable

sum = 1;

count = 1;

% for loop from 2 to 1000, we have taken upper limit as 1000 otherwise the sum exceedes 1000

for temp = 2:1000

sum = sum + temp;

count = count + 1;

% If sum exceeds 1000 then break

if (sum > 1000)

break;

end

end

% Display the output

fprintf('We need to add %d consecutive numbers to get a sum greater than 1000', count)

Proof:

1 + 2 + 3 +..................... + 44 = 990 < 1000

1 + 2 + 3 +............................ + 45 = 1035 > 1000
