Please let me know how to get the following outputs using C++.



First one

come on!

Hey Jones21 .... what does it mean ... come on ...
you just placed the links of hosting websites.... i asked here for help.... regarding these loops...

I think you should try this code,

#include <iostream>
using namespace std;
int main (){
int i,j,k,a;
char mat[5][5];
for (i=0;i<5;i++){
for(j=0;j<5;j++){
k=(i-j);
do{
if (k>=0){
mat[i][j]='+';
cout<<mat[i][j];}
else {
cout<<" ";}}
while (a=0);}
cout<<"\n";}
system("PAUSE");
return 0;}

First one :

#include <iostream>
using namespace std;

int main()
{
int i,j,k;
for( i =1;i<=6;i++)
{

for(j=1;j<i;j++)
{
cout<<" "<<j;
}
for( k=j-2;k>0;k--)
{
cout<<" "<<k;
}
cout<<endl;
}

}

Second one :

#include <iostream>
using namespace std;

int main()
{
int i,j;

for(i=5;i>0;i--)
{
for(j=i;j<=5;j++)
{
cout<<" "<<j;
}
cout<<endl;
if(i==1)
goto xy;
}

xy:

for(i=6;i>0;i--)
{
for(j=1;i-j>0;j++)
{
cout<<" "<<j;
}
cout<<endl;
}
}

Third one:

#include <iostream>
using namespace std;

int main()
{
int i,j,k=1;

for(i=0;i<4;i++)
{
for(j=0;j<k;j++)
{
cout<<" "<<i;
}
k=k+2;
cout<<endl;
}
}


try it................
