Well you first start off by formatting your code.
Then you might as well update your code dump with an actual question or description of a problem.

It's been a long time since I've done C++ but I'm pretty sure if you have #include you need a file name to go along with it. You have 2 empty #includes.

For starters, you need a { after int main()

Read the question carefully.
Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.

A function definition is not a single statement - it always starts and ends with a curly bracket pair.
Then you have a spurious ")" in the "Array After Transpose" for loop.
Try:

C++

#include<stdio.h>
#include<conio.h>
int main()
    {
    int i,j,a[3][3];
    for(i=0;i<3;i++)
        {
        for(j=0;j<3;j++)
            {
            scanf("%d",&a[i][j]);
            }
        }
    //Array Without Transpose
    //Display
    for(i=0;i<3;i++)
        {
        for(j=0;j<3;j++)
            {
            printf("%d",a[i]);
            }
        printf("/n");
        }
    //Array After Transpose
    for(j=0;j<3;j++)
        {
        printf("%d",&a[j]);
        }
    getch();
    }

But do yourself a favour: one character variable names are easy to type, but they don;t tell you what they are used for. For a trivial example like this, it's not a major problem, but if your course starts to build on this, it can become very helpful if you use "proper names" that describe what the data is rather than "a" for example.

Quote:
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
printf("%d",a[i]);
}
printf("/n");
}
//Array After Transpose
for(j=0;j<3;j++))
{
printf("%d",&a[j]);
}

Should be instead:

C

for(i=0;i<3;i++)
   {
     for(j=0;j<3;j++)
     {
       printf("%d ",a[i][j]);
     }
     printf("/n");
   }
   //Array After Transpose
   for(i=0;i<3;i++)
   {
     for(j=0;j<3;j++)
     {
       printf("%d ",a[j][i]);
     }
     printf("/n");
   }
