What you are doing is printing the value in the array at spot [3][3], which is invalid for a 3by3 array, you need to loop over all the spots and print them.
for(int i = 0; i < 3; i++) {
for(int j = 0; j < 3; j++) {
printf("%d ", array[i][j]);
}
printf("\n");
}
This will print it in the following format
10 23 42
1 654 0
40652 22 0
if you want more exact formatting you'll have to change how the printf is formatted.

There is no .length property in C. The .length property can only be applied to arrays in object oriented programming (OOP) languages. The .length property is inherited from the object class; the class all other classes & objects inherit from in an OOP language. Also, one would use .length-1 to return the number of the last index in an array; using just the .length will return the total length of the array.
I would suggest something like this:
int index;
int jdex;
for( index = 0; index < (sizeof( my_array ) / sizeof( my_array[0] )); index++){
for( jdex = 0; jdex < (sizeof( my_array ) / sizeof( my_array[0] )); jdex++){
printf( "%d", my_array[index][jdex] );
printf( "\n" );
}
}
The line (sizeof( my_array ) / sizeof( my_array[0] )) will give you the size of the array in question. The sizeof property will return the length in bytes, so one must divide the total size of the array in bytes by how many bytes make up each element, each element takes up 4 bytes because each element is of type int, respectively. The array is of total size 16 bytes and each element is of 4 bytes so 16/4 yields 4 the total number of elements in your array because indexing starts at 0 and not 1.

I'm trying to print out an array with a set number of rows and variable columns. It can print one and two columns fine but any higher than three, it just shows three total cells.
#include<stdio.h>
int main(void)
{
int N = 0;
int i = 0;
int j = 0;
double container [6][N];
printf("Please enter the number of containers to be entered: ");
scanf("%d", &N);
for (i=0; i<6; i++){
for(j=0; j<N; j++){
container [i][j] = 0;
printf("%lf ", container[i][j]);
}
printf("\n");
}
return 0;
}With 2 as input:
Please enter the number of containers to be entered: 2 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000
When higher than 2:
Please enter the number of containers to be entered: 3 0.000000 0.000000 0.000000

I'm really surprised no one has said this yet, do not use VLAs (variable-length-arrays) in C. In order to achieve what you're doing, you need to allocate memory dynamically using malloc() or calloc() from the stdlib.h library. Here's some example code I put together really quickly. #include #include int main(void) { // six rows of unallocated int pointers (arrays in this case) int* container[6]; int n; printf("enter columns: "); scanf(" %d", &n); for (int i = 0; i < 6; ++i) { // this is where we allocate memory for the n columns container[i] = (int*)malloc(sizeof(int) * n); } for (int i = 0; i < 6; ++i) { for (int j = 0; j < n; ++j) { // assigning some random data here container[i][j] = (i + 1) * (j + 1); } } for (int i = 0; i < 6; ++i) { for (int j = 0; j < n; ++j) { // showing the dummy data printf("%d ", container[i][j]); } printf("\n"); } for (int i = 0; i < 6; ++i) { // freeing the allocated memory. free(container[i]); } return 0; }

How to Print Array Elements in a Given Order with or without a Function
February 16, 2023 - In this way, we can take each value from the user and store it in our array in a sequential way. Keep in mind that the array always starts from the 0 index (the first element is at index 0, the second is at index 1, and so on). Now it is time to print all the array elements (the value that each index of the array has) in the given order.

You have to print each element individually; C doesn't have a built-in way to print the entire array at once. An array in C is just a sequence of objects of a given type; there's no metadata to tell you the number of elements, their type, etc. Array expressions "decay" to a pointer to their first element, and that pointer doesn't give any of that information either. Operations on arrays are limited. Array expressions cannot be the target of an assignment; you can't write something like int arr[5]; arr = {0, 1, 2, 3, 4}; // NOT ALLOWED You would have to assign each element individually: for (int i = 0; i < 5; i++ ) arr[i] = i; or use the memcpy or strcpy (for strings) library functions: memcpy(arr, (int []){1, 2, 3, 4, 5}, sizeof arr); Array sizes are fixed; you can't add or remove elements at runtime. There's no "slicing" operation where you can easily grab a subset of the array. In short, they're not like lists at all.

That is the memory address of the array (because of array-to-pointer decaying).
To correctly print pointers though, you should use %p.

The "wierd" value you get from printing array is actually the memory address of the first element of the array.
In order to print an array, you need to use a for loop:
for (int i = 0; i < array_size; i++)
printf("%d\n", array[i]);

November 4, 2023 - This C program initializes an array with 5 integers and then prints each element sequentially. While the for loop is the most common method to traverse and print an array, you can achieve the same with while loops and do-while loops.
Top answer 1 of 5

you need to iterate through the array's elements
float foo[] = {1, 2, 3, 10};
int i;
for (i=0;i < (sizeof (foo) /sizeof (foo[0]));i++) {
printf("%lf\n",foo[i]);
}
or create a function that returns stacked sn printf and then prints it with
printf("%s\n",function_that_makes_pretty_output(foo))

You have to loop through the array and printf() each element:
for(int i=0;i<10;++i) {
printf("%.2f ", foo[i]);
}
printf("\n");
