Avoiding End-of-line (\n) after using Scanf.

[theprofoundgeek]

Hi,

I am writing a C code to add two matrices. I want to take input with a feel of real martice, some thing like

1 2 3
4 5 6
7 8 9

but the Scanf function automatically enter EOL and hence my input looks some thing like this,

1
2
3

4
5
6

7
8
9

any idea how to get this thing straight?

Here is the Code :

 
// Write a program to add two matrices.
 
#include <stdio.h>
#include <conio.h>
 
void main()
 
{
        int row,column,**ptrA,**ptrB,**ptrC,counter1,counter2;
        clrscr();
 
        printf("Enter the number of row of the matrices to be processed:");
        scanf("%d",&row);
 
        printf("\nEnter the number of columns of the matrices to be processed:");
        scanf("%d",&column);
 
        ptrA=(int**)(calloc(row,sizeof(int *)));
        ptrB=(int**)(calloc(row,sizeof(int *)));
        ptrC=(int**)(calloc(row,sizeof(int *)));
 
        for (counter1=0;counter1<row;counter1++)
        {
            *(ptrA+counter1)=(int*)(calloc(column,sizeof(int)));
            *(ptrB+counter1)=(int*)(calloc(column,sizeof(int)));
            *(ptrC+counter1)=(int*)(calloc(column,sizeof(int)));
        }
 
        printf("\n\n\nEnter the values for First Matrice:\n\n\n");
 
        for (counter1=0;counter1<row;counter1++)
        {
            for (counter2=0;counter2<column;counter2++)
            {
 
                   printf(" \t");
 
                   scanf("%d",**((ptrA+counter1)+counter2));
 
 
            }
            printf("\n");
        }

Replies would be greatly appreciated!

P.s : Not - so - profound after this problem

You want the input to look like ...

• a decimal number
• some whitespace
• a decimal number
• some whitespace
• a decimal number
• newline

You need the scanf format string to reflect this desired input format.

@donbock
Donbock, that is a feasible solution, but the problem is that the number of elements to be scanned is dynamic, so how can I decide the length of scanf format string. Any Idea?

[donbock]

Construct the scanf format string dynamically based on the entered number of columns.

Copy text from stdin to an array and then parse the array contents.
