How to do the Sum practice with the for loop

I am not understanding how to put this together. I have an idea on how it works but i cannot put the coding together with the knowledge level im at. It explains that it takes an input of 1 to 5 and you have to add them together and output the sum. But when you actually do the challenge, it puts the inputs as 100 and wants an outcome of 5050. I just don't understand how I suppose to put it together and i have looked at the comments and discussions but I cannot find the right answer for this. And I have to do this before it lets me go on to the next lesson.

Bigbling135 , to give you hints we need to see your code. > please put it in playground, save it and place a link to it here.

Bigbling135 this place is not for getting ready made code ,it will be better if you link your code , cuz it will help to understand you questions and get better solution by the community

int n; cin >> n; int p = 0; for(int o=5;o>=0;o--) { int sum = n + p; } cout << sum; } This is what I have and I know its wrong but I just cannot figure out on how to put it together where one variable would add 5 different numbers together and then display the total. I am only up to for loops because I have to finish this challenge/practice before I can move on. EDIT: I went looking for answers about it and found this one very simple one and I still don't understand how when 100 gets put into it and it becomes 5050. This is the code I found. int n; cin >> n; int sum=0; for(;n>0;n--) { sum+=n; } cout << sum; }

100 + 99 + 98 + 97..................+ 1 = 5050;

You can try this ! int i; int sum=0; For(i=1;i<=5;i++) { Sum=sum+1; } cout<<"the sum is"<<sum;

It took me a little bit to understand the code I found and thanks for the help. The main issue I am having issues with now is understanding how to get a variable to add itself multiple times. I can kinda see how sum+=n works but im just not understanding how this stores and adds itself together. Got a little bit of a learning disability so it just makes it harder for me.
