for loop to sum up the integer

here is the question generate a random integer n in the range from 5 to 9 then loop n times to: -prompt the user for an integer between 1 to 10 -print the sum of the numbers entered so far

here what I got:

n = randi([5,9]);
totalsum = 0;
runsum = 0;
for i = n
    int = input('Enter an integer between 1 and 10 :');
    runsum = runsum + int;
    totalsum = runsum + totalsum;
end

I try to call up the loop, like, Enter an integer between 1 and 10 : 8 but it did not countinous to count up the sum

Can anyone have some suggestion for me?

try this:

n = randi([5,9]);
totalsum = 0;
runsum = 0;
for i=1:n
    int = input('Enter an integer between 1 and 10 :');
    runsum = runsum + int;
    totalsum = runsum + totalsum;
end
totalsum

good luck

You are executing your 'for' loop for only one value, n. Also, I think you probably want to remove your totalsum variable (it doesn't store the total sum... runsum will have the total sum at the end of the loop). Try this:

n = randi([5,9]);
runsum = 0;
for i = 1:n
    int = input('Enter an integer between 1 and 10 :');
    runsum = runsum + int;
    disp(['   Sum so far: ', num2str(runsum)]);
end

thanks for your answer

My answer is correct. The answer you accepted was submitted after mine and isn't correct (it doesn't output the correct number).

Prompt the user for two integersand write a programthat will calculate the summationand the product of all the integers between those inputs inclusively. what is the answer
