Hi,
You have to use two for loops to display these kind of output.

the for loops can be:-

for( i=1; i<5; i++)
for( j=1; j<=i; j++)
print ( j )


and to search a integer in an 2D array u hve to use again two for loops.

karan is true i would help you about finding a integer from the 2D arrays
you shold write 2 for loops and a if state like that

int search;

for(int i;i<size;i++)
for(int j;j<size;j++)
if(array[i][j]==search)
return 0;

can be...

code of the your problem is very simple

#include <iostream.h>
#include <conio.h>
void main()
{
clrscr();
int search;
int arr[row][colom]={{here enter the element of array}};
cout<<"enter the element to be search";
cin>>search;
for(int i=0;i<=row;i++)
{
for(int j=0;j<=colom;j++)
{
if(arr[i][j]==search)
break;
}
}
cout<<"no can be found at the position of:" <<arr[i][j];
getch();
}

how can i make a program which can calculate factorial using C++

[D_C]

int factorial(int n)
{
  int result = 1;
  while(n > 1)
  {
    result *= n;
    n--;
  }
  return result;
}

hi khan,
this is in simple c++
if you want to use class or some other concepts than will send you



void fac(int num)
{
int fac=1;
for(i=num;i>=1;i--)
{
fac=fac*i;
}
cout<<"Factorial ="<<fac;
getch();
}

try this

A recursive factorial

int fact(int n)
{
if (n == 0)
return 1;

return ( n * fact( n-1 ) );
}
