This is a code of to solve the prime numbers. But it has a problem,the print results is not prime numbers entirely.And it print many repeat numbers.The code as follows: #include"math.h"

At first i do not know why the b array output result is different for the two code as follows. No long after,i found that because the b array is out of bounds.The b array is only include five elements.So

After compiled and ran for this code.When i input 1 on control,then control output 2.At first i do not understand that why control output 2. No long after,i understand because that the program must carry

I want to write a code to print rhombus with use C program language.This code would used six for statements.The previous three for statements be used to print the upper five lines.After three for statements
