read array

Posted Date Unknown Johnson Augustine 4 Comments

In C language i have a statement to read and print two dimen matrix using array .

for(i=0;i<2;i++)

{

for(j=0;j<2;j++)

{

// A is an integer array

//no is also decl as int

printf("Enter number");

int a[i][j]=scanf("%d",&no)

printf("%d",a[i][j]);

}

printf("ln");

}

and i given input to the program in two way first i given values seperated by space like 10 20 30 40 and get the output in a matrix form

in second case i given input by presssing enter each time

and got out put in

My doubt is that what process is happened in first case ? The compiler is using any stack or any data structure ?

Why the printf statement works only ones or not ? , the reason for getting matrix form in first case . ?

thanks in-advance

What value is returning for this expression?

int a[i][j]=scanf("%d",&no) ;
printf("%d",a[i][j]);

Can you explain what your intention here?

Hi,

Don't stick with the code , i just try to explain what i am try to do ,[Ignore syntax ]

I just try to know the difference between inputing values in to a program . in the following way

1) type value and press enter

2) Input all values separated by a space

How the compiler interrupt these values , thats only ,Matrix and somthing somthing is just for an example

Hi,

From my knowledge it is handled by a stream buffer , and interpreted by Language compiler

is it right?

Yes I think the implementation is also compiler dependent. I had observed different behavior for the same scenario like this for Turbo C++ and Visual C++ compilers..
