Thanks for the quick response but what would be printed?
I just need someone to confirm that I'm using the precedence rules correctly.

printf("%d \n", 2 > !3 && 4 - 1 != 5 || 6);

2 > 0 && 3 !=...

Really quick: Can someone explain in the order in which to read this?

printf("%d \n", 2 > !3 && 4 - 1 != 5 || 6);

Thanks!

Yay fixed using:


for (k=0;k<4;k++) {
printf("a[&#37;d][] = %f %f %f %f\n",k+1,*A[k],*A[k]+1,*A[k]+2,*A[k]+3);
}


My problem now is that it prints values but it prints the wrong values:

Great catch Elysia!

This may be a stupid question but what kind of value is it if not a float?

I switched up my code a little bit but my understanding may be faulty here:

A = (double **)calloc(16, sizeof(double *));
Allocates enough memory for 16 doubles?


for(row=0;row<4;row++)
{...

I'm trying to make my matrix a 4x4 matrix. What's the indication that it's a 16x16 matrix?

I think my program is crapping out because of faulty memory allocation.

I want my code to read matrix.dat and store the numbers in a 4x4 matrix using pointer ........... Then I would like to print...

Not quite sure how this exactly works. Why am I not allocating anything at A[n] and why is there no memory to hold the sscanf data?

This is my altered code:



if ((Inf_1 == NULL))
{
printf("Error opening the file\n");
exit(1);
}

I want my code to read matrix.dat and store the numbers in a 4x4 matrix using pointers. Then I would like to print the matrix line by line. Although my program compiles, I get a core dump error...

this is my modified code (declared prototypes, tried to fix the factorial equation):


#include <stdio.h>
#include <math.h>

double Intgr(double m, int n, double A, double a, double b);...

I'm trying to call multiple functions to calculate an integral on the interval 0 < a < b.

My code compiles and it seems to call up the functions correctly but I get a weird number for an answer....

Problem solved! I defined the variables in the "ugly way" at first but I tried to find a more elegant solution. I tried putting sscanf in the k loop but I didn't know how to stop it from scanning the...

It seems the print only v[0] if I explicitly tell it to print v[0], v[1], v[2] etc



#include <stdio.h>
#include <math.h>
#include <stdlib.h>

int main(){
int k;

Those tips are great. Thank you very much.

My code is compiling but my vectors aren't being stored correctly. This is my output:

Hi I was wondering if it was possible to store a data file in an array:

The data file (vec_in.dat) would look like this :

1.2 -2.3 0.53 2.01 -1.5

I'm trying to store these 5 numbers in an...

... damn.

I'm trying to create a program that would first read a list from a data file containing names of people and their sales and then calculate the amount of commission each person makes. I'm trying to...

I changed the "case '1'" to a "case 1:" but the output still only prints "unrecognized operator". Any way to circumvent this problem?

Thanks for the indents Salem! I'm coding on putty so I gave up...

Thanks for the input so far guys.

I modified the printfs to include a \n at the end of each one.

Now the problem is that it won't recognize the operator. This is the output:

Enter -1<x<1:...

My switch statement embedded in my do loop doesn't seem to execute correctly:



#include <stdio.h>
#include <math.h>
int main()
{
double x, y, y2;
int n_term;

My program compiles fine in CC but incorrectly in GCC:




#include <stdio.h>
#include <math.h>
int main()
{
double x, i, S;

Thanks for the tip arpsmack!

Now I can compile my code but my output is like this:

Sphere ( 1) Radius = 0.0 Area = 0.000 Volume = 0.000
Sphere ( 2) Radius = 0.0 Area = 0.000...

Can anyone tell me why my C code can't compile:


#include <stdio.h>
#include <math.h>
#define PI = 3.1415926

int main()
{
int k;
