Need help writing an algorithm for this program

[Crisis757]

{
int age;
cout <<"Enter Age"
<< end1;
cin >> age;
cout <<"The age you entered is" << age
return 0
}

An algorithm is a sequence of steps that describe what a program should do. It is normally written before the program. So, if you can describe step by step what this program does, that is the algorithm. It is not rocket science. Just tell us what you think this program does, in point form. Since this is a small program, you may have to be explicit.

For example.

Step 1 - Declare an integer variable int
Step 2 - Display "Enter age"
Step 3 -  ....

Here is the definition of algorithm...

hey all I am beginner in IT and want to over that , Please i have a problem with algorithm, can you give me tips on how to go about it. here is th problem am trying to solve:

Write the following program and run it.

#include
#include
#include

int GCD_Euclid(int x, int y);
int GCD_EuclidRec(int x, int y);
int GCD_Simple(int x, int y);
bool isPrime(int x);
bool isprime_Rec(int x,int z);
using namespace std;
void main(int argc)
{
int x,y;

for(int rep=1; rep<=5; rep++){
srand(time(NULL)*rep);
x= rand()%100;
y= rand()%100;

cout << "GCD of " << x << " and " << y << " is " << GCD_Euclid(x,y) << endl;
cout << "GCD of " << x << " and " << y << " is " << GCD_EuclidRec(x,y) << endl;
cout << "GCD of " << x << " and " << y << " is " << GCD_Simple(x,y) << endl;
cout<
