Noob here. Would you suggest learning c++ directly or do c before c++?

You are given an integer N. You need to print the series of all prime numbers till N.
Input Format
The first and only line of the input contains a single integer N denoting the number till where you need to find the series of prime number.
Output Format
Print the desired output in single line separated by spaces.
Constraints
1<=N<=1000
Jhagrut
Input
9
Your Code's Output
10
Expected Correct Output
2 3 5 7
Compilation Log
Compiled successfully.

Ok
Stanislav
this code reminded me this https://github.com/AceLewis/my_first_calculator.py/blob/master/my_first_calculator.py
klimi
Idk the answer
First result https://www.tutorialspoint.com/c_standard_library/c_function_printf.htm
Hehehehe
please give c++ program file

Possible issue is my understanding level of how c memory works in case of int and float I think
Artöm
You dont need float

In the for loop the number gets divided by 10 till it becomes single digit ..And you're printing just that digit.

If it is 352 youll only get Three then

Yes but that's not happening

352 is being 3.52

Input_float= 3.52

Input is of int data types
Anonymous
Input = input_float

Means input becomes 3 right?
Anonymous
If so in switch output with be three

Now i am doing( input_float - input)*10
