# 2-23c# Base Loop Statements

The loop statement must have four elements: initial conditions. Cycle conditions. Loop body. State change

for (initial condition; cyclic condition; state change)
{
Loop body
}

Simple example

for (int i=1;i<=10;i++)//start loop from 1 until the i=10 end loop is satisfied

Console.WriteLine ("I");//cycle record (i) final output (i)

Problem of the day

Seeking prime numbers

` intsum =0; //Loop 2-100 between all the numbers             for(intj =2; J <= -; J + +)            {                intCount =0; //in this loop view the number of current loops can be divisible several times                 for(inti =1; I <= J; i++)                {                    if(j% i = =0) {Count++; }                }                //if it is divisible 2 times, the description is prime                if(Count = =2) {sum+=J;                Console.WriteLine (j); }} Console.WriteLine (sum);`

The use of prime numbers can only be divisible by itself and 1 in defining a variable full count=2 is prime

Find odd even and output separately

Nothing difficult to do when it was not thought how to separate output

`intsum =0; //Loop 2-100 between all the numbers             for(intj =2; J <= -; J + +)            {                intCount =0; //in this loop view the number of current loops can be divisible several times                 for(inti =1; I <= J; i++)                {                    if(j% i = =0) {Count++; }                }                //if it is divisible 2 times, the description is prime                if(Count = =2) {sum+=J;                Console.WriteLine (j); }            }`
