Hello everyone!! I have a problem about memory allocation, i use calloc() to initialize all elements in array to be zero. This is my code: #include <stdio.h> #include <conio.h> #include <stdlib.h> #include <time.h> #define sizes 1200 main() { double** arr; int m[sizes]; int i,j,k; srand((unsigned)time(NULL)); arr= (double **) calloc(sizes,sizeof(double*)); for(k=0; …

Hello, everyone! I am trying to generate a random number with Java, but random with the fix number of reviewers per object.Example: I have 5 reviewers(r(i)) and 5 objects(o(j)), a[i][j] is the evaluation score that reviewer(r(i)) has evaluated object(o(j)), and my question is i want to labeled each object should …

i want to make random numbers for x[row][col] that row =10 and col =10, but my problem is: how i fix random numbers of n[col]=5; here is my code: public static void main(String[] args){ double[][] x= new double[10][10]; int row,col; int n[]={0,0,0,0,0,0,0,0,0,0}; for(row=0; row<10; row++ ){ for(col=0; col<10; col++){ if( …

Dear all sir, i'm a begining of java and i have a problem to write the equation in java code , i want to make it in for loop and i also want to count it by column.how do i do? please me!!! example: f[1][1]=5.4; f[2][1]=5.0; f[3][1]=1.5; k[1][1]=|f[1][1]-f[2][1]|+|f[1][1]-f[3][1]-|; k[2][1]=|f[2][1]-f[1][1]|+|f[2][1]-f[3][1]-|; k[3][1]=|f[3][1]-f[1][1]|+|f[3][1]-f[2][1]-|;

i have problem about the output in this code, my output so only the index 0. how can i fix this. [code] public class d_2D { static double[][] d =new double[6][4]; static double[][] e= {{}, {0.0,0.6,0.0,0.0}, {0.0,0.2,0.5,0.1}, {0.0,0.2,0.5,0.4}, {0.0,0.2,0.5,0.7}, {0.0,0.0,0.0,0.9}}; static double[] avg= new double[4]; static double[] sum= new double[4]; …
