can any one help me need urgently 2morow is TEST

[PINKA]

hey
can any one help me in
i want to make a program in "C" in which user can enter a row , column and matrix(2D ARRAY) based on that row and column. that matrix should be diplayed
but the condition is
both insertion and deletion must be perform in two seperate function let say "insert" and "disp" and that func must be call in main

actully my program is not working properly its not giving me the right output

#include<conio.h>
#include<stdio.h>

void main()
{
static int m1[100][100];
int row1,col1;
int i,j;

printf("\n Enter the no. of rows and colomns of matrix : \n");
scanf(" %d %d",&row1,&col1);
printf("\nEnter the matrix elements : \n");

for(i=0;i<row1;i++)
{
for(j=0;j<col1;j++)
scanf("%d",&m1[i][j]);
}

printf("\nThe matrix you entered is : \n");
disp(m1,&row1,&col1);
getch();
}
disp(int *mat, int *row, int *col)
{
int i, j, r, c;
r=*row;
c=*col;

for(i=0;i<r;i++)
{
for(j=0;j<c;j++)
printf("\n%d", *(mat+i*c+j) );
}
}

I'd start with getting rid of conio.h and getch(). They're useless and non-standard, so they won't port to any other systems that don't have your same version of conio.h (plus they dont' change the way your program operates, as far as I can see).

Then I'd match up your brackets - it looks like one of your functions is missing one.

Are you trying to declare a function disp(), or is that a call to stdio.h or ::shudder:: conio.h? I think that might be where you're missing your '}'

thanks sir
but the thing is this program is not working properly actully when i call the func"disp" in main at that time the outpit shows bye this function only first row of matrix all other rows elements are zero. but the actully i hadn't insert zero any where like if i inser row =2 column=2 and matrix elent as 1, 2, 3, 4,
than it shows 1, 2, 0, 0,


so plese tell me where is my mistake and it would be best if you tell my mistake and show me through source code

PLZZZZZZZZZZ HELP me

the simplest thing is to use array notation in function disp() rather than pointers, e.g.

#include<conio.h>
#include<stdio.h>
 
int main()
{
static int m1[100][100];
int row1,col1;
int i,j;
 
printf("\n Enter the no. of rows and colomns of matrix : \n");
scanf(" %d %d",&row1,&col1);
printf("\nEnter the matrix elements : \n");
 
for(i=0;i<row1;i++)
{
for(j=0;j<col1;j++)
scanf("%d",&m1[i][j]);
}
 
printf("\nThe matrix you entered is : \n");
disp(m1,&row1,&col1);
getch();
}
 
// specify number of elements in right most indicies
disp(int mat[][100], int *row, int *col)  
{
int i, j, r, c;
r=*row;
c=*col;
 
for(i=0;i<r;i++)
{
for(j=0;j<c;j++)
    printf("%d ", mat[i][j] );  // use array notation
printf("\n");
}
}
