system ("pause"); /* execute M$-DOS' pause command */
return 0;
)
set up variables properly:
int k = 0;
int n = 0;
prompt the user:
cout << "type a freaking number --> ";
get the input
cin >> k;
multiply by three:
n = k*3;
then display the new result:
cout << endl << n;
o now i get it thanks yor trigering back my memory um but hey i have another question what does endl mean and what would happen if you put the values 4 to k and 5 to n
also i changed it now and there is still errors here is the program curently and its errors i cant figure out how to correct the errors ok here bye the way i have a dev c++ compiler
#include <stdlib.h>
using namespace std;
int main(int argc, char **argv)
{
int k,n;
k = 0;
n = 0;
cout<<"type a number";
cin>>k;
n=k*3;
cout<<endl<<n;
system ("pause"); /* execute M$-DOS' pause command */
return 0;
)
