for(outer=1;outer<=4;outer++)
{

for(b=0;b< inner;b++){ //for the spaces
printf("%d ",nPyramid);
nPyramid = nPyramid + 1; //Increase the pyramid value by 1
}

nPyramid = nPyramid - 1; //Remove this line and see the effect
printf("\n"); //Next line

inner = inner -1;

}
getch();

Where the code that you don't understand? Any question?

#include <iostream>


using namespace std;

int main()
{
int outer;
int inner = 4;
int nPyramid = 1;
int b;

for(outer=1;outer<=4;outer++)
{

for(b=0;b<inner;b++)
{                   //for the spaces
cout<<nPyramid;

nPyramid++;         //Increase the pyramid value by 1
}

nPyramid--; //Remove this line and see the effect
cout<<endl; //Next line

inner--;

}

}


The same program above.
I just changed some C thigns in C++.
