```c
#include <stdio.h>
int max(int a, int b) {
return a > b ? a : b;
}
int knapsack(int W, int wt[], int val[], int n) {
int i, w;
int K[n + 1][W + 1];
for (i = 0; i <= n; i++) {
for (w = 0; w <= W; w++) {
if (i == 0 || w == 0) {
K[i][w] = 0;
} else if (wt[i - 1] <= w) {
K[i][w] = max(val[i - 1] + K[i - 1][w - wt[i - 1]], K[i - 1][w]);
} else {
K[i][w] = K[i - 1][w];
}
}
}
return K[n][W];
}
int main() {
int val[] = {60, 100, 120};
int wt[] = {10, 20, 30};
int W = 50;
int n = sizeof(val) / sizeof(val[0]);
printf("Maximum value: %d", knapsack(W, wt, val, n));
return 0;
}
