Reading a file in c with .csv as extension. The file consisting of both integer and float type data values. Is there any way to read the csv file. Any help is appreciated.

I'm traying to read from a file two things :
1- a list of integers(on the top of the file) in to an array of integers inputs[]
2- 3 matrixes 5x5 etch into an array of array of array boards[][][]
the firs part works properly but when the 2 part finished some how the inputs[] change values
The code :
void loadfile(const char* filepath,int *inputs ,int boards [nboards][size][size]){
FILE *inp=fopen(filepath,"r");
//loading the marked numbers
for(int i=0;i<4;i++){
fscanf(inp,"%d",inputs+i);
//to show that inputs reseve the the right values at the start
printf("%d ",*(inputs+i));
fseek(inp,ftell(inp)+1,SEEK_SET);
}
printf("\n");
//loaing the boards
for(int n=1;n<=nboards;n++){
for(int i=0;i<size;i++)
for(int j=0;j<size;j++){
fscanf(inp,"%d",&boards[n][i][j]);
printf("%d ",boards[n][i][j]);
}
printf("\n");
}
fclose(inp);
}
int main(){
int inputs[4]={};
int boards[nboards][size][size]={};
loadfile("inputs.txt",inputs,boards);
for(int i=0;i<4;i++)
printf("%d ",*(inputs+i));
}
The file :

I want to export the results of a discriminant analysis by using asdoc in stata.
I want to show as follows.
three Three Decimal Digits.
compress the table to fit into a page of the word.
However, the format of the results is horrible. I use dec(3) but not working. I read the "help asdoc" in Stata, but it all about regression.
Does anyone know how to export the total results of discriminant analysis to Word with nice format?
Thank you in advance.
The following is the sample code and asdoc code that I use.

Your segmentation fault is because you're trying to read a nonexistent index in the argument vector of main. If you want to avoid that, you should rewrite it to match something like this:
int main (int argc, const char *argv[]) {
if (argc > 1 && (number_threads = atoi(argv[1]))) {
max_nodes = 0;
readAdjMatrix();
}
return 0;
}
This ensures that you have an argument to convert to begin with, and also that it is a nonzero number. I believe atoi has undefined behavior if it isn't a valid string though, so you should harden against that. You also do some other unnecessary things. For one, this block here:
for(int i = 0 ; i < MAX_VERTICES ; i++){
for(int j = 0 ; j < MAX_VERTICES ; j++){
global_adj_matrix[i][j] = 0;
}
}
is pointless because if you initialize a 2D array as an external/global variable then it is automatically zeroed upon initialization. Only local/automatic variables will be filled with garbage data. Therefore, you can omit it.
Finally, I would also change your while loop to look more or less like this (Credit: Chux for better loop guard).
while(fscanf(file_pointer, "%d %d %d", &source, &destination, &edge_weight) == 3) {
global_adj_matrix[source][destination] = global_adj_matrix[destination][source] = edge_weight;
if(edge_weight > max_weight)
max_weight = edge_weight;
if(destination > max_nodes)
max_nodes = destination;
}
This ensures you correctly scanned the amount of variables necessary per line. And the extended assignment just saves a bit of room.
Hope this fixed the problem you were having.
I am posting my answer by neglecting the bigger code which you have not mentioned in your question. I have trimmed down the unnecessary code. The code is given below.
#include <stdio.h>
#include <unistd.h>
#include <ctype.h>
#include <string.h>
#include <stdlib.h>
#include <math.h>
#include <limits.h>
#define MAX_VERTICES 1024
int global_adj_matrix[MAX_VERTICES][MAX_VERTICES];
int global_weight,max_nodes,random_node,max_weight;
void readAdjMatrix();
int main()
{
int i,j;
max_nodes = 0;
readAdjMatrix();
return 0;
}
void readAdjMatrix()
{
int source, destination, edge_weight,i,j;
max_nodes = INT_MIN;
max_weight = INT_MIN;
FILE *file_pointer = fopen("graph.txt", "r");
while(!feof(file_pointer))
{
fscanf(file_pointer, "%d", &source);
fscanf(file_pointer, "%d", &destination);
fscanf(file_pointer, "%d", &edge_weight);
global_adj_matrix[source][destination] = global_adj_matrix[destination][source] =edge_weight;
if(destination > max_nodes)
max_nodes = destination;
}
printf( "%d\n", max_nodes);
for( i = 0 ; i <= max_nodes ; i++){
for( j = 0 ; j <= max_nodes ; j++){
printf("%d\t", global_adj_matrix[i][j]);
}
printf("\n");
}
fclose(file_pointer);
}
PS : Simply execute this code with ./a.out with no command line argument. In case you are using the command line argument (as given in your question), please use the following syntax to execute your code :
./a.out "your desired number which works with the bigger code"
I have two 4-by-4 arrays:
a1 = [ 1 2 3 4; 5 6 7 8; 9 10 11 12; 13 14 15 16 ]
a2 = [ 17 18 19 20; 21 22 23 24; 25 26 27 28; 29 30 31 32 ]
I need to create 16-by-8 array C:
1 2 3 4 17 18 19 20
1 2 3 4 21 22 23 24
1 2 3 4 25 26 27 28
1 2 3 4 29 30 31 32
5 6 7 8 17 18 19 20
5 6 7 8 21 22 23 24
5 6 7 8 25 26 27 28
5 6 7 8 29 30 31 32
9 10 11 12 17 18 19 20
9 10 11 12 21 22 23 24
9 10 11 12 25 26 27 28
9 10 11 12 29 30 31 32
13 14 15 16 17 18 19 20
13 14 15 16 21 22 23 24
13 14 15 16 25 26 27 28
13 14 15 16 29 30 31 32
The left half (from 1st to 4th column) of the result array C should repeat 4 times i-th row of the array a1, the right half (from 5th to 8th column) should repeat 4 times the array a2.
Below is my code.
p=4
n=4
for i=1:n
b=n*i;
a=n*(i-1)+1;
for j=1:p
for k=a:b
C(k,j)=a1(i,j);
end;
end;
end;
for i=1:n
b=n*i;
a=n*(i-1)+1;
for j=p+1:2*p
l=1;
for k=a:b
C(k,j)=a2(l,j-p);
l=l+1;
end;
end;
end;
C;
size_C=size(C)
Question. Is it possible to create result array C without for-loop? Which functions can I use?
Yes it's possible.
One way of doing it is by using kron and repmat
C = [ kron(a1, ones(4,1)) repmat(a2, 4, 1)]
Perhaps the 4 should be derived from the size of one of the matrixes
You can use ndgrid to generate the row indices and then concatenate:
[ii, jj] = ndgrid(1:size(a2,1), 1:size(a1,1));
C = [a1(jj,:) a2(ii,:)];
With focus on performance, here's one using reshape and repmat -
% Store sizes
M = size(a1,1);
N = size(a2,1);
% Get the replicated version for a1 and a2 separately
parte1 = reshape(repmat(reshape(a1,1,M,[]),[N,1,1]),M*N,[])
parte2 = repmat(a2,[M,1]);
% Do columnar concatenatation for final output
out = [parte1 parte2]
Sample run on a generic case -
a1 = % 3 x 4 array
5 2 6 9
7 4 7 6
9 8 6 1
a2 = % 2 x 5 array
7 7 1 9 2

I want write a SQL Query to get results in C12WR column.
And I want on row of C12WR Column use a static value which is in “SC_12” (In the shown table the value is “510.4”) and in the SC_12 Column it should calculate the below formula after 13th row number and it continue it till the end of the table records
After 13th Row in C12WR Column = (the value of above row*11 + Current row value from C_P Column) /12
The final output should be similar to below
S_NO_ T_P O_P H_P L_P C_P SC_12 c12-WWR

I don't know what you mean by a static value which is in “SC_12” But if you have that value in the table then use this:
select T_P, O_P, H_P, L_P, C_P, SC_12
case when t1.S_NO_ > 12
then cast ((t2.SC_12 * 11 + t1.C_P)/12 as varchar(50))
else ''
end as [c12-WWR]
from t as t1
inner join t as t2 on t2.S_NO_ = t1.S_NO_ -1
order by t1.S_NO_
