This is a C Program to implement Bin packing algorithm. This is a sample program to illustrate the Bin-Packing algorithm using next fit heuristics. In the bin packing problem, objects of different volumes must be packed into a finite number of bins or containers each of volume V in a way that minimizes the number of bins used. In computational complexity theory, it is a combinatorial NP-hard problem.

There are many variations of this problem, such as 2D packing, linear packing, packing by weight, packing by cost, and so on. They have many applications, such as filling up containers, loading trucks with weight capacity constraints, creating file backups in media and technology mapping in Field-programmable gate array semiconductor chip design.

Here is source code of the C Program to Implement the Bin Packing Algorithm. The C program is successfully compiled and run on a Linux system. The program output is also shown below.

`#include<stdio.h>`

void binPacking(int *a, int size, int n) {

int binCount = 1, i;

int s = size;

for (i = 0; i < n; i++) {

if (s - *(a + i) > 0) {

s -= *(a + i);

continue;

} else {

`binCount++;`

s = size;

`i--;`

`}`

`}`

printf("Number of bins required: %d", binCount);

`}`

int main(int argc, char **argv) {

printf("Enter the number of items in Set: ");

int n;

int a[n], i;

int size;

scanf("%d", &n);

printf("Enter %d items:", n);

for (i = 0; i < n; i++)

scanf("%d", &a[i]);

printf("Enter the bin size: ");

scanf("%d", &size);

binPacking(a, size, n);

return 0;

`}`

Output:

$ gcc BinPacking.c $ ./a.out Enter the number of items in Set: 5 Enter 5 items:12 23 34 45 56 Enter the bin size: 70 Number of bins required: 3
