How to display a number and all that is less than that number then sum them.

So Iā€™m working on a code to figure out how to have a user input a number like 5 and have it display 12345 then add them up to equal the sum so in this case It be 15. Iā€™ve tried lots of things and the result is always either just the single number that was input or the range of numbers. I have to use a for loop but I always get a warning that ā€œiā€ is used initialized Iā€™m the function ā€œfor( a=bla; 1 < i; i++) help overall would be very greatly appreciated

So you don't need to use loops here. Already exists a expression to calculate this. Here check my code: https://code.sololearn.com/cE4FK4CxiOQj In this case use looping is bad for efficiency time
