First Class Test

Write a random four of 100 or less within 20 minutes

C + + program source code:

#include <iostream>

#include <ctime>

using namespace Std;

int main ()

{

int i,j,k;

Srand ((unsigned) time (NULL));

for (int a=0; a<30;a++)

{

I=rand ()%100;

J=rand ()%100;

K=rand ()%4;

if (k==1)

cout<<i<< "+" <<j<< "=" <<endl;

if (k==2)

cout<<i<< "-" <<j<< "=" <<endl;

if (k==3)

cout<<i<< "*" <<j<< "=" <<endl;

if (k==0)

cout<<i<< "/" <<j<< "=" <<endl;

}

return 0;

}

Not completed in 20 minutes because the rand () function is unskilled and does not have much practice.
